Opis:
A sliding mode controller for the photovoltaic pumping system has been proposed in this paper. This system is composed of a?photovoltaic generator supplying a?three-phase permanent magnet synchronous motor coupled to a?centrifugal pump through a?three-phase voltage inverter. The objective of this study is to minimise the number of regulators and apply the sliding mode control by exploiting the specification of the field oriented control scheme (FOC). The first regulator is used to force the photovoltaic generator to operate at the maximum power point, while the second is used to provide the field oriented control to improve the system performance.The whole system is analysed and its mathematical model is done. Matlab is used to validate the performance and robustness of the proposed control strategy.

Opis:
Research related to photovoltaic panels comprises different topics starting with modelling solar cells, finding new maximum power point tracking (MPPT) algorithms, testing existing ones or designing of DC/DC converters for MPPT systems and microgrids that incorporate photovoltaic energy sources. In each of the examples above a deep knowledge of photovoltaic panels is required, as well as a reliable measurement system that can deliver continuous, stable light with enough power to meet standard test conditions (STC) and that can ensure repeatable results. Therefore this paper presents a low-cost solar simulator with a microcontroller-based measurement system, that can be used for various measurements of low-power photovoltaic panels.

Opis:
Photovoltaic (PV) system generates renewable energy from sunlight, which has low efficiency due to the variance in nature of temperature and irradiance in a fast changing environment condition. Different researchers have proposed different maximum power point tracking MPPT techniques to improve the efficiency. However, still there are many open issues. Thus, to address this, a non-linear back-stepping-based higher order sliding mode controller (BHOSMC) is proposed to harvest maximum power from PV system. The PV module and load is interfaced by a non-inverted buck-boost converter (NIBBC). A linear interpolation method is used for voltage generation and Lyapunov stability is used to verify the control system equation. MATLAB/Simulink software is used for testing the proposed controller performance. The experimental result verified that the proposed BHOSMC is robust, accurate and fast tracking, faultless and less chattering as compared to perturb and observe (P&O), back-stepping control (BSC) and back-stepping-based sliding mode control under rapidly varying meteorological condition.

Opis:
Energy efficiency is one of most critical parameters in photovoltaic (PV) systems. Overall PV system efficiency improvement may be achieved by such means as topological changes, new generations of transistor switches and/or planar magnetic components use. But on the other hand whole system must follow the wheather changes such as solar energy delivery variation due to cloud shading as well as temperature fluctuations. In such conditions a driver should dynamically track maximum power point (MPPT) of a PV array. For the purposes of better understanding PV array performance the paper shows MatLab simulation of 3.2 kWp PV array. The driver discussed works with a range of different step up DC-DC converter topologies such as bridge based topologies as well as interleaved ones. The ASCII protocol which can be implemented in PC application is responsible for working parameters settings carrying and output data logging as well as current software status check. The paper presents practical implementation of the driver as a part of larger PV system where the interleaved DC-DC converter works with 3.2 kWp PV array of ten PV modules connected in parallel. Described MPPT algorithm takes advantage of modified Perturb and Observe (P&O) method. Presented are microcontroller hardware resources utilization, functional software architecture and developped MPPT algorithm which performance is shown on the plot.

Opis:
W kształceniu inżynierów na kierunku energetyka realizowanym na Wydziale Elektrotechniki i Informatyki Politechniki Rzeszowskiej szczególną wagę przykłada się do znajomości odnawial-nych nośników energii. W niniejszym artykule przeanalizowano różne techniki MPPT omawiane w ramach przedmiotu „niekonwencjonalne źródła energii”. Wykorzystanie OZE wymaga zasto-sowania przekształtników energoelektronicznych. Moc generowana przez moduły fotowoltaiczne czy też generatory wiatrowe jest zależna od tego, w jakim punkcie charakterystyki prądowo- -napięciowej pracują. Za kontrolę optymalnych wartości napięcia i natężenia prądu, dla których moc generowana przez moduł PV jest najwyższa, odpowiada algorytm śledzenia punktu mocy maksymalnej (MPPT).
In education in the majoring of Energetics at the Faculty of Electrical and Computer Engineer-ing of Rzeszow University of Technology, special attention is paid to the knowledge of renewable energy carriers. This article explores various MPPT techniques lectured in “Unconventional ener-gy sources”. The use of renewable energy resources requires the use of energy converters. The power generated by photovoltaic modules or wind generators is dependent on the point at which the current-voltage characteristics work. For control of the optimum voltage and current values for which the power produced by the PV module is highest, the MPPT algorithm is the equivalent of the maximum power point tracking (MPPT) algorithm.

Opis:
Non-uniform conditions on the modules of the PV array, especially, partial shading reduces the output of the PV array to a large extent. The shaded module in a string limits the current of the entire string and hence, the output power of the string. The output power under such conditions is reported to be higher for total-cross-tied (TCT) configuration. This paper describes two different approaches, one based on current compensation (current equalization) and another based on voltage equalization, to extract higher power from the partially shaded total-cross-tied photovoltaic array. The TCT configuration is considered to minimize the number of converters, sensors, cost and complexity involved. The additional converters in the two distinct approaches evaluated here operate only when the partial shading occurs and are controlled to minimize the current and voltage miss-matches. The analysis and the control algorithm are presented. Simulation results obtained in MATLAB/Simulink are included to demonstrate the effectiveness of both methods and the relative merits and demerits of these approaches are highlighted.

A Novel Intelligent control of a Unified Power Quality Conditioner (UPQC) coupled with Photovoltaic (PV) system is proposed in this work. The utilization of a Re-lift Luo converter in conjunction with a Cascaded Artificial Neural Network (ANN) Maximum Power Point Tracking (MPPT) method facilitates the optimization of power extraction from PV sources. UPQC is made up of a series and shunt Active Power Filter (APF), where the former compensates source side voltage quality issues and the latter compensates the load side current quality issues. The PV along with a series and shunt APFs of the UPQC are linked to a common dc-bus and for regulating a dc-bus voltage a fuzzy tuned Adaptive PI controller is employed. Moreover, a harmonics free reference current is generated with the aid of CNN assisted dq theory in case of the shunt APF. The results obtained from MATLAB simulation.

This paper attempts to validate the performance of a power injection control block for Photovoltaic Generation Systems (PVGS). This device uses a control module based on detecting the power injected into the supply by the inverter, instead of measuring the power generated by the PVGS. The performance is evaluated using the concept of Maximum Energy Curve that takes into account both transient and permanent control performance. The paper presents a basic and simple procedure to obtain a model from the manufacturer characteristic curves of the photovoltaic cells. MATLAB Simulink is used as simulation tool to obtain the response of the proposed system to changes in temperature and irradiance.

Opis:
The wind energy conversion systems (WECS) suffer from an intermittent nature of source (wind) and the resulting disparity between power generation and electricity demand. Thus, WECS are required to be operated at maximum power point (MPP). This research paper addresses a sophisticated MPP tracking (MPPT) strategy to ensure optimum (maximum) power out of the WECS despite environmental (wind) variations. This study considers a WECS (fixed pitch, 3KW, variable speed) coupled with a permanent magnet synchronous generator (PMSG) and proposes three sliding mode control (SMC) based MPPT schemes, a conventional first order SMC (FOSMC), an integral back-stepping-based SMC (IBSMC) and a super-twisting reachability-based SMC, for maximizing the power output. However, the efficacy of MPPT/control schemes rely on availability of system parameters especially, uncertain/nonlinear dynamics and aerodynamic terms, which are not commonly accessible in practice. As a remedy, an off-line artificial function-fitting neural network (ANN) based on Levenberg-Marquardt algorithm is employed to enhance the performance and robustness of MPPT/control scheme by effectively imitating the uncertain/nonlinear drift terms in the control input pathways. Furthermore, the speed and missing derivative of a generator shaft are determined using a high-gain observer (HGO). Finally, a comparison is made among the stated strategies subjected to stochastic and deterministic wind speed profiles. Extensive MATLAB/Simulink simulations assess the effectiveness of the suggested approaches.

Opis:
This paper presents a comparative study between the conventional PI (Proportional Integral) and backstepping controllers applied to the DFIG (Doubly Fed Induction Generator) used in WECS (Wind Energy Conversion System). These two different control strategies proposed in this work are developed to control the active and reactive power of the DFIG on the one hand, and to maintain the DC-link voltage constant for the inverting function on the other hand. This is ensured by generating control signals for two power electronic converters, RSC (Rotor Side Converter) and GSC (Grid Side Converter). In order to optimise the power production in the WT (Wind Turbine), an MPPT (Maximum Power Point Tracking) algorithm is applied along with each control technique. To simulate the effectiveness of the proposed controllers, MATLAB/Simulink Software is used, and the obtained results are analysed and discussed to compare PI and backstepping controllers in terms of robustness against wind speed variations and tracking performance in dynamic and steady states.

Opis:
When it comes to reducing emissions caused by the generation of electricity, among different renewable energy sources, the solar energy gains prominence, due to its geographical availability, simplicity of implementation, and absence of physical moving parts. However, the performance of photovoltaic systems is dependent on environmental conditions. Depending on temperature and solar irradiation, the photovoltaic (PV) system has an operating point where maximum power can be generated. The techniques that are implemented to find this operating point are the so-called maximum power point tracking (MPPT) algorithms. Since weather conditions are variable in nature, the output voltage of the PV system needs to be regulated to remain equal to the reference. Most of the existing studies focus either on MPPT or on voltage regulation of the PV system. In this paper, the two-stage PV system is implemented so that both MPPT and voltage regulation are achieved simultaneously. Additionally, an improved version of the perturb and observe (P&O) algorithm based on artificial potential fields (APF), called APF-P&O, is presented. According to the results of the simulations carried out in MATLAB/Simulink software, the APF-P&O method is more efficient than the conventional method.

Opis:
Photovoltaic (PV) cells are very costly because of the silicon element which is not cheaply available. Usually, PV cells are preferred to be used at maximum efficiency. Therefore, PV plants are emphasized to extract maximum power from PV cells. When inertia free PV plants are integrated into the grid in large numbers, the problem of maintaining system stability subjected to load perturbation is quite difficult. In response to this, a control topology is being an approach to make available the PV cells in maintaining system stability by utilizing the system frequency deviation as feedback to the controller. To implement this, the PVs are operated at Maximum Power Point Tracking (MPPT). This allows the PV to operate at Pseudo Maximum Power Point tracking (PMPPT) which makes it possible to run the PV with reserve power capacity without employing a battery for storage. The control strategy has been implemented over a two-stage power conversion model of the PV system. The simulation results showed that the proposed control PMPPT topology is effective in frequency regulation capability as compared to the MPPT technique.

W artykule zaprezentowano strukturę przekształtnika pełniącego funkcję sprzęgu między siecią energetyczną prądu przemiennego a źródłem energii odnawialnej – panelami fotowoltaicznymi (PV). Opisywane rozwiązanie odznacza się wysokim współczynnikiem sprawności, przy jednoczesnym zachowaniu bardzo dobrych parametrów jakościowych przekształcanej energii. W wyniku zastosowania falownika sieciowego pracującego w regulacji nadążnej prądu osiągnięto prąd sieciowy o małej zawartości niepożądanych harmonicznych i teoretycznie zerowej mocy biernej. Ze względu na sposób funkcjonowania ogniw fotowoltaicznych, których wydajność zależy nie tylko od panujących warunków atmosferycznych, ale również i od sposobu obciążenia, szczególną uwagę zwrócono na zaimplementowany algorytm MPPT. Jego zadaniem jest zapewnienie takiego punktu pracy ogniwa PV, aby podążać za punktem mocy maksymalnej zależnie od warunków pracy systemu. Przedstawiono również wybrane wyniki badań.
