Opis:
Every solar panel has a maximum operating power. However, when solar panels are directly connected to a battery, the panels are usually forced to operate at the battery voltage. This is almost always below the maximum power point of the panels, thereby causing panel under-utilization. To overcome this problem, maximum power point trackers (MPPT) have been developed. In this thesis, a technical comparative analysis is done between two commonly implemented MPPT (Perturb & Observe and Incremental Conductance) algorithms to ensure efficient maximum power point tracking. This is done by modelling a maximum power point tracker (MPPT) and integrating it into a PV system in the MATLAB/SIMULINK environment. These two direct MPPT algorithms are then implemented under changing solar irradiation and load conditions. From the simulations, when starting from 0 second, the P&O algorithm reaches the Pmpp of 1969 W at 26ms, while INC reaches the Pmpp of 1965 W at 49ms. In addition, when there is a change in the AC loads connected to the PV system, it took exactly 35ms for both algorithms to reach the Pmpp of 2488 W. However, when both algorithms reached their Pmpp values, INC shows more stability than the P&O. The P&O shows ripples even at steady irradiance states, although the ripples are more evident when the irradiance is changing. From the results displayed, it can, therefore, be concluded that the P&O algorithm will be more suited to applications where attaining the Pmpp within a relatively short time is a necessity, while INC should be applied where performance is of great importance.

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.

Opis:
Photovoltaic panels have a non-linear current-voltage characteristics to produce the maximum power at only one point called the maximum power point. In the case of the uniform illumination a single solar panel shows only one maximum power, which is also the global maximum power point. In the case an irregularly illuminated photovoltaic panel many local maxima on the power-voltage curve can be observed and only one of them is the global maximum. The proposed algorithm detects whether a solar panel is in the uniform insolation conditions. Then an appropriate strategy of tracking the maximum power point is taken using a decision algorithm. The proposed method is simulated in the environment created by the authors, which allows to stimulate photovoltaic panels in real conditions of lighting, temperature and shading.

Opis:
The solar photovoltaic output power fluctuates according to solar irradiation, temperature, and load impedance variations. Due to the operating point fluctuations, extracting maximum power from the PV generator, already having a low power conversion ratio, becomes very complicated. To reach a maximum power operating point, a maximum power point tracking technique (MPPT) should be used. Under partial shading condition, the nonlinear PV output power curve contains multiple maximum power points with only one global maximum power point (GMPP). Consequently, identifying this global maximum power point is a difficult task and one of the biggest challenges of partially shaded PV systems. The conventional MPPT techniques can easily be trapped in a local maximum instead of detecting the global one. The artificial neural network techniques used to track the GMPP have a major drawback of using huge amount of data covering all operating points of PV system, including different uniform and non-uniform irradiance cases, different temperatures and load impedances. The biological intelligence techniques used to track GMPP, such as grey wolf algorithm and cuckoo search algorithm (CSA), have two main drawbacks; to be trapped in a local MPP if they have not been well tuned and the precision-transient tracking time complex paradox. To deal with these drawbacks, a Distributive Cuckoo Search Algorithm (DCSA) is developed, in this paper, as GMPP tracking technique. Simulation results of the system for different partial shading patterns demonstrated the high precision and rapidity, besides the good reliability of the proposed DCSA- GMPPT technique, compared to the conventional CSA-GMPPT.

Opis:
The major goal of electric power companies is to give the quantity of electricity claimed by each consumer. This does not function without posing problems because consumption increases with time and the production will not be adequate to cope with the need for electricity. Besides, we may face environmental issues such as the increase of CO2 in the world, the conditions of producing energy, the difficulty of easily, quickly and economically storing large quantities of electricity. One of the solutions that could restrict and solve the problems is the production of renewable energy. In this paper, we focus on photovoltaic products; we present the photovoltaic conversion chain such as modeling, adaptation and control systems, as well as photovoltaic characteristics and system analysis methodology and planning of a photovoltaic system based on the OOPP method (Objectives Oriented Project Planning).

Opis:
A single photovoltaic panel under uniform illumination has only one global maximum power point, but the same panel in irregularly illuminated conditions can have more maxima on its power-voltage curve. The irregularly illuminated conditions in most cases are results of partial shading. In the work a single short pulse of load is used to extract information about partial shading. This information can be useful and can help to make some improvements in existing MPPT algorithms. In the paper the intrinsic capacitance of a photovoltaic system is used to retrieve occurrence of partial shading.

Opis:
Analiza wybranych zagadnień równoległej pracy dwóch układów przesyłowych prądu stałego (HVDC) o odmiennych technologiach, tj. układu tyrystorowego (LCC – Line Commutated Converter) i tranzystorowego (VSC – Voltage Source Converter) jest przedmiotem niniejszego referatu. Pokazano, że równoległa praca układów jest możliwa w warunkach niskiej mocy zwarciowej tam, gdzie sam układ LCC o równoważnej mocy nie mógłby pracować stabilnie w trybie regulacji mocy. Warunkiem jest praca falownika łącza VSC HVDC w trybie regulacji napięcia AC. Z drugiej strony w określonych okolicznościach to właśnie ten tryb może być przyczyną pogorszenia warunków pracy układu LCC, co wskazuje na potrzebę dokładnej analizy takich przypadków celem właściwego doboru nastaw odpowiednich układów regulacji.
This paper describes the results of an analysis of selected problems in the parallel operation of two HVDC systems based on different technologies, namely Line Commutated Converter (LCC HVDC) and Voltage Source Converter (VSC HVDC). Using Maximum Power Curves (MPC) technique it is shown that the parallel operation of the two systems in low short circuit power conditions is possible where a single LCC HVDC scheme of equivalent rated power would fail to operate stably in constant power mode. However, the prerequisite for such operation is active AC voltage control offered by the VSC inverter. It is also shown that the positive influence of the VSC converter is noticeable if the two inverters are a considerable distance apart (e.g. 100 or 200 km). On the other hand, EMTP simulations reveal also adverse effects of the mutual influence, particularly apparent in low ESCR systems where the so-called voltage and power instability problem of the AC/DC systems is be more evident. This phenomenon is the basic cause of the undesirable interaction between the LCC HVDC and VSC HVDC resulting in more difficult return to nominal operating conditions after a commutation failure in the LCC system. The proposed and demonstrated solution is to tune down the PLL and voltage controller gains in order to make the overall system less stiff.

Opis:
The output characteristics of photovoltaic (PV) arrays are nonlinear and change with the solar irradiance and the cell's temperature. Therefore, a maximum power point tracking (MPPT) technique is needed to draw peak power from the solar array to maximize the produced energy. Among the hill climbing methods, the perturb and observe (P&O) method tracks the maximum power point (MPP) by repeatedly increasing or decreasing the output voltage at the MPP of the PV module. The implementation of the method is relatively simple, but it cannot track the MPP when the irradiance varies quickly with time. In addition, itmay cause system oscillation around the peak power points due to the effect of measurement noise. The incremental conductance (IncCond) method is also often used in PV systems. This method tracks the MPPs by comparing the incremental and instantaneous conductances of the solar array. This method requires longer conversion time, and a large amount of power loss results. In addition, extra hardware circuitry is required to implement the system. In this paper, it is shown that the negative effects associated with such a drawback can be greatly reduced if the intelligent method is used to improve P&O and IncCond algorithms. The perturbation step is continuously approximated by using fuzzy logic controller (FLC). By the digital simulation, the validity of the proposed control algorithm is proved.

Opis:
A solar photovoltaic (PV) system has been emerging out as one of the greatest potential renewable energy sources and is contributing significantly in the energy sector. The PV system depends upon the solar irradiation and any changes in the incoming solar irradiation will affect badly on the output of the PV system. The solar irradiation is location specific and also the atmospheric conditions in the surroundings of the PV system contribute significantly to its performance. This paper presents the cumulative assessment of the four MPPT techniques during the partial shading conditions (PSCs) for different configurations of the PV array. The partial shading configurations like series-parallel, bridge link, total cross tied and honeycomb structure for an 84 PV array has been simulated to compare the maximum power point tracking (MPPT) techniques. The MPPT techniques like perturb and observe, incremental conductance, extremum seeking control and a fuzzy logic controller were implemented for different shading patterns. The results related to the maximum power tracked, tracking efficiency of each of the MPPT techniques were presented in order to assess the best MPPT technique and the best configuration of the PV array for yielding the maximum power during the PSCs.

When the machine is at high speed, serious problems occur, such as high frequency loss, difficult thermal management, and the rotor structural strength insufficiency. In this paper, the performances of two high-speed permanent magnet generators (HSPMGs) with different rotational speeds and the same torque are compared and analyzed. The two-dimensional finite element model (FEM) of the 117 kW, 60 000 rpm HSPMG is established. By comparing a calculation result and test data, the accuracy of the model is verified. On this basis, the 40 kW, 20 000 rpm HSPMG is designed and the FEM is established. The relationship between the voltage regulation sensitivity and power factor of the two HSPMGs is determined. The influence mechanism of the voltage regulation sensitivity is further revealed. In addition, the air-gap flux density is decomposed by the Fourier transform principle, and the influence degree of different harmonic orders on the HSPMG performance is determined. The method to reduce the harmonic content is further proposed. Finally, the method to improve the HSPMG overload capacity is obtained by studying the maximum power. The research showed that the HSPMG at low speed (20 000 rpm) has high sensitivity of the voltage regulation, while the HSPMG at high speed (60 000 rpm) is superior to the HSPMG at low speed in reducing the harmonic content and increasing the overload capacity.

Opis:
This paper proposes a system design and control technique for a newly developed brushless and permanent magnetless synchronous generator-based variable-speed wind energy generation system, transferring power to a constant voltage dc grid via a three-level Vienna rectifier (VR). The recently established generator named Brushless Induction excited Synchronous Generator (BINSYG) is a wound field synchronous generator (WFSG), whose excitation is developed by controlling an Induction Machine fitted to the same machine structure and sharing the same magnetic core. A new controller is proposed that ensures the stable operation of BINSYG for a wide variation of shaft speeds. VR achieves sinusoidal input current and can control the power factor at its input, which is particularly suitable for wind energy applications. The top and bottom capacitor voltages of the VR are balanced using redundant switching combinations. The system with its proposed control algorithm is modelled in MATLAB/Simulink for a 5 kW rated BINSYG feeding power to a 750 V dc grid. The steady-state and dynamic state simulation results are presented and the controller performance is verified for a wide range of wind speeds. Further, real-time results using the OPAL-RT testbed are presented for the same system to verify the effectiveness of the overall control strategy.
