Opis:
Rozwój technologiczny implikuje ciągły wzrost popytu na energię, co stwarza potrzebę kontroli jej produkcji, dystrybucji i konsumpcji. Powstaje w tym zakresie wiele nowych rozwiązań, zarówno technologicznych, jak i systemowych. Mając powyższe na uwadze, zoptymalizowane zarządzanie energią promujące ekologiczne zachowania w różnych skalach jest niezwykle istotne. Zarządzanie energią to tematyka często podejmowana przez autorów literatury, jednakże brak w niej jednolitej nomenklatury podziału zagadnienia. Opracowania traktują jedynie o konkretnych zastosowaniach przedmiotu niniejszego artykułu. Autor podejmuje próbę stworzenia klasyfikacji podziału zarządzania energią w różnych wymiarach, opierając się na badaniach literatury przedmiotu. Ponadto artykuł zawiera odniesienie wielu płaszczyzn energetyki do funkcji zarządzania.
Technological development implies a constant increase in energy demand, which creates a need for an effective tool for control of its production, distribution and consumption. There are a variety of solutions that have come up recently in the technological and system approach to this cause. Having said this, optimized energy management which promotes eco-friendly behaviors in different scales seems to be essential. Energy management is a subject widely taken up by literature authors, yet it has not been summarized and its consistent nomenclature has not been created. Existing works only consist of specified solutions of the described subject. The author attempts to create a classification of division of energy management in its many dimensions on the basis of a related literature review. Moreover, this article refers many perspectives of energy to main management functions.

Opis:
Today, with the longing for smart and sustainable transportation, the elevator industry has undergone major metamorphism in the field of control algorithm, electric drive, and the motor. Amongst these, regenerative drive (RD) plays a pivotal role in making elevator technology more energy efficient. Rather than wasting the recovery energy from the machine as heat, RD recovers it as green energy. Conventional direct current (DC) motors ruled the elevator industry for many years and were adopted as standard type of elevator motors. But with the advancement in electric drive technology, alternating current (AC) motors, especially induction motors, flourished in the later part. Recently with the introduction of Permanent Magnet Synchronous Motors (PMSM) technology, the elevator revolution began in terms of power quality, ride quality, and green energy. Likewise, contrasted with different types of vertical transportation machines, PMSMs have better powerful execution, compact size, and higher system-level efficiency. Recently, with the rapid improvement in intensity hardware, utilization of rare earth magnetic materials, and indubitably advanced research, PMSM has rapidly changed systems globally. PMSM is a multivariable, nonlinear, and high-coupling framework. The torque and stator current present a unique capacity connection. Attractive fields can be decoupled to gain decent power outcomes. With the presentation of regenerative PMSM, electrical drives coupled to system integrated frameworks for recovery energy has enhanced savings in power consumptions.

The paper discusses the feasibility of installing renewable energy generation technologies on sea-going transport, taking into account the additional weight and power consumption. This study in based on the power management of a 26,198 tonne commercial chemical tanker. The management system would aim at reducing the number of generators as well as the power required from burning fossil fuels. After a process of elimination of potential technologies based on feasibility of the project and shipboard application, the work is focused towards photovoltaic and wind energy generation in combination with fossil fueled engines and Li-ion battery storage covering the higher energy density needs, and the intermittent nature of renewables. The network architecture is optimized in order to have the highest efficiency, and reduced system weight. The results show that successful management of the system can lead to reduction in generator requirement, and energy despite the weight of extra installations of photovoltaic and wind energy generation systems. By reducing the number of generators and allowing each remaining one to operate near their maximum power, the specific fuel consumption is improved, the efficiency is increased, resulting in significant fuel and cost saving, along with the mass of fuel to be carried on-board.

A bottleneck for the development of public transport vehicles is their electricity supply. Electric buses are almost exclusively equipped with electrochemical batteries, while nearly 40% of the energy is used in the processes of air conditioning. For this reason, we developed and built a demonstration system for storing thermal energy in public transport vehicles. The most important effects are: significant reduction of financial expenses and of the total weight of all batteries with the same amount of stored energy.

Opis:
In recent years, there has been a significant development in “green” and energy efficient propulsion systems, which fits into the general trend of environmentally friendly “green shipping”. The pursued goal is to construct a safe passenger ship that is low in energy demand and equipped with a highly energy efficient, emission-free propulsion system. The paper presents main problems encountered by designers of a small, hybrid-powered ferry powered lithium batteries. The conducted research allowed to create a design of an energy efficient hull shape, which decreases the demand for energy. Completed remote control model tests resulted in a proposal of an energy efficient and safe propulsion system with good manoeuvring capabilities. Measurements completed on an existing ferry permitted completing energy balance and forming an energy management policy. The paper contains the emission calculations computed for the existing ferry that are necessary for the environmental impact analysis. The soon to be constructed, newly designed vessel will provide a valuable contribution to hybrid-propulsion, energy management and unmanned technologies research.

The increase of renewable non-programmable production and the necessity to locally self-consume the produced energy led to utilize ever more storage systems. To correctly utilize storage systems, an opportune management method has to be utilized. This paper implements a multi-period management method for storage systems, using different management strategies. The method aims to minimize the total absorbed and supplied energy or the peak power exchanged with the grid. The results show the effectiveness of the method in diminishing the energy exchanged with the grid and also the possibility to optimize the performance of the storage systems.

Opis:
This present study contribute to provide a simple technology to early detect the phenomenon of spontaneous coal combustion. A new prototype is designated to detect the CO gas formation as a product of initial coal oxidation. Moreover, several parameters including coal quality, coal weight sample, ambient temperature, and air flow were employed to investigate the effects of each parameter to the CO formation time. The results show that the coal characterisation have a significant effect in the CO formation time where the coal having a higher fixed carbon and high grass calorific values provide the high liability of spontaneous coal combustion. However, these finding only occurred in low weight sample where in the high coal weight sample only fixed carbon plays the main role in determining the CO formation time. Furthermore, the prototype ambient temperature become the important parameter in the boosting of CO formation time where airflow only enhance the CO formation time in low temperature condition (below 29°C). Moreover, these findings opens a new sight in coal management, especially in Indonesia, where controlling the coal and atmosphere temperature could effectively prevent the spontaneous coal combustion especially in coal stockpile. Nevertheless, the other factor including airflow and coal weight sample also need perfect controlling because all of these factors potentially create a perfect environment to combust the coal spontaneously.

Opis:
The paper presents a circuit structure that can be used for powering an IoT (Internet of Things) sensor node and that can use energy just from its surroundings. The main advantage of the presented solution is its very low cost that allows mass applicability e.g. in the IoT smart grids and ubiquitous sensors. It is intended for energy sources that can provide enough voltage but that can provide only low currents such as piezoelectric transducers or small photovoltaic panels (PV) under indoor light conditions. The circuit is able to accumulate energy in a capacitor until a certain level and then to pass it to the load. The presented circuit exhibits similar functionality to a commercially available EH300 energy harvester (EH). The paper compares electrical properties of the presented circuit and the EH300 device, their form factors and costs. The EH circuit’s performance is tested together with an LTC3531 buck-boost DC/DC converter which can provide constant voltage for the following electronics. The paper provides guidelines for selecting an optimal capacity of the storage capacitor. The functionality of the solution presented is demonstrated in a sensor node that periodically transmits measured data to the base station using just the power from the PV panel or the piezoelectric generator. The presented harvester and powering circuit are compact part of the sensor node’s electronics but they can be also realized as an external powering module to be added to existing solutions.

The aim of the study is to show the impact of investments in photovoltaic installations carried out by local government units on the implementation of the objectives of the climate and energy package in the Rzeszów Functional Area (ROF). It has been shown that such an important problem as the need to increase the share of renewable energy sources (RES) in electricity production is also solved locally. The methods of in-depth interview, case study and desk research were used. The application of modern technologies in the field of energy production with the use of photovoltaic cells in the ROF area is to contribute in 2019-2035 to the reduction of CO2 emissions; to the increase in the production of electricity from RES, and to the reduction of the use of fossil fuels for the production of electricity. Diversification of energy sources, also at local and individual level, can be beneficial not only for the environment, but also for the budget of energy consumers.

Opis:
The development of electromobility is focused on the design and implementation of increasingly more effective electric drives. In such a system, apart from energy recovery, it is not possible to recharge the batteries while driving. Electric vehicles equipped with fuel cells and a battery (FCHEV – fuel cell hybrid electric vehicle) in a parallel configuration boast increased energy transfer capabilities. The article presents an energy flow analysis in a parallel hybrid drive system with fuel cells and a battery. The research was carried out on a 30 W vehicle made in 1:10 scale with a NiMH battery and a fuel cell with a proton exchange membrane (PEM). Increasing driving dynamics causes a 29% increase in energy consumption, 43.6% reduction of energy transfer from a fuel cell and a 23% increase of in the energy share intended for battery charging. Continuous operation of the system in full power mode ensures a much greater efficiency of energy transmission to the drive train (95%) compared to the system operating in dynamic driving conditions – 64–75%.

Opis:
One of the fundamental aspects of the organization management is determination of appropriate strategy for the adoption of development directions and organization areas that needs improvement in the context of existing opportunities and threats based on the organization strengths. The aim of the paper is analysis of the strengths and weakness of E-Guides of European universities in the context of its applying in Erasmus+ programme. Paper is a result of scientific international cooperation of Polish Erasmus coordinator with Turkish Erasmus student.
Zwiększenie udziału odnawialnych źródeł energii w produkcji energii elektrycznej ze względu na ich zależność od pogody, zmienne zapotrzebowanie na energię w czasie, a także ochrona środowiska wymusza zmianę podejścia do zarządzania systemem elektroenergetycznym i wprowadzanie nowych rozwiązań. W artykule przedstawiono możliwości zarządzania energią i jej efektywniejszego wykorzystanie poprzez zastosowanie magazynów energii. Omówiono kryteria magazynowania i wybrane formy magazynowania energii elektrycznej. Zwrócono uwagę na niektóre istotne wady i zalety wymienionych magazynów energii elektrycznej. Podkreślono, iż nie istnieje jedna, uniwersalna metoda magazynowania energii elektrycznej i równolegle należy rozwijać różne technologie magazynowania, by odpowiadały na zróżnicowane potrzeby.

Opis:
The aim of the article is to identify and analyze how to manage the energy supply chain as part of public-private partnership and to try to answer the question in what direction should the Polish industry go to compete on global markets in the face of many challenges of decarbonisation? Maybe by using green energy produced close to its recipients and supplied bypassing the transmission grid? Maybe through the diversification of installations processing energy from various sources (RES), which would constitute an additional regulatory value for the power system? Could solutions, e.g. based on a direct line system, help in such a difficult technological and regulatory time for the energy market? As a research problem, an attempt was made to answer the question to what extent, for example, a systemic approach based on the model of direct lines can help strategic industry organizations in managing the energy supply chain, especially in situations of energy crisis? What actions can be taken to keep a secure energy supply chain management system operational or how to deal with threats affecting the functioning of the energy supply chain? The essence is to emphasize the role of the energy supply chain management system, based on specific requirements or innovative solutions, e.g. a sharing system or direct lines, in maintaining an appropriate level of energy supply security, especially during an energy crisis. To what extent can the requirements of reference documents focusing on operational control and process control ensure the security of the energy supply chain? With regard to the research problems defined in this way, the working hypothesis was formulated as follows: Searching for innovative solutions in the energy sector, and in particular the implementation of direct systems, can effectively counteract or at least reduce the effects of the recent electricity crisis and increase economic attractiveness for the industry. The article uses theoretical and empirical research methods adapted to the problems posed and the purpose of the article. These include: analysis of the literature, normative and legal documents and internal system documentation of sample organizations, the audit method using direct interview and observation of processes and activities.

Opis:
The main objective of energy audit is to present any irregularities in work of energy facilities and show possibilities of increasing energy efficiency. There is possibility to perform different types of energy audits: basic energy audit (presents basic and cheap improvements), full energy audit (contains a lot of measurements and full economical analysis) or individual energy audit (analyzes selected part of the production process or energy installation). First part of article contains question, which management should discuss before decision on preparing energy audits. This issues helps choose type of report and processes to analyze. Additionally management can plan the amount of financed expenses related to energy modernization and connected profits. There is possibility to delegate person from company to prepare an energy audit. Is this a reasonable decision? Auditor has an experience and has worked with a lot of different energy problems. This means that proposed solutions will be more vary and economic analyzes will include more aspects. Furthermore auditor will evaluate objective with comparison to employees. Auditor needs a lot of data to prepare reliable report. Therefore cooperation between company staff and auditors should proceed properly. Article contains examples of questions, which can be included in the questionnaire, and steps of updating documents. Finished report is discussed on a final meeting, where management decides which improvement will be implementing. After modification it is recommended to prepare another energy audit.

Opis:
Recently, there has been a significant development of ecological propulsion systems, which is in line with the general trend of environmentally friendly “green shipping”. The main aim is to build a safe, low-energy passenger ship with a highly efficient, emission-free propulsion system. This can be achieved in a variety of ways. The article presents the main problems encountered by designers and constructors already at the stage of designing the unit. The research conducted made it possible to create a design with an effective shape of the hull, with the prospect of an energy-efficient and safe propulsion system with good manoeuvrability. The scope of the research included towing tank tests, recalculation of the results in full-scale objects and a prediction of the energy demand of the propulsion system. The results obtained were compared to indicate power supply variants depending on the hull shape.
