Optimal Design of MPPT Controllers for Grid Connected Photovoltaic Array System

Abstract Integrating photovoltaic (PV) plants into electric power system exhibits challenges to power system dynamic performance. These challenges stem primarily from the natural characteristics of PV plants, which differ in some respects from the conventional plants. The most significant challenge is how to extract and regulate the maximum power from the sun. This paper presents the optimal design for the most commonly used Maximum Power Point Tracking (MPPT) techniques based on Proportional Integral tuned by Particle Swarm Optimization (PI-PSO). These suggested techniques are, (1) the incremental conductance, (2) perturb and observe, (3) fractional short circuit current and (4) fractional open circuit voltage techniques. This research work provides a comprehensive comparative study with the energy availability ratio from photovoltaic panels. The simulation results proved that the proposed controllers have an impressive tracking response. The system dynamic performance improved greatly using the proposed controllers.

This proposal is aimed to overcome the problem that arises when diverse regulation devices and controlling strategies are involved in electric power systems regulation design. When new devices are included in electric power system after the topology and regulation goals were defined, a new design stage is generally needed to obtain the desired outputs. Moreover, if the initial design is based on a linearized model around an equilibrium point, the new conditions might degrade the whole performance of the system. Our proposal demonstrates that the power system performance can be guaranteed with one design stage when an adequate adaptive scheme is updating some critic controllers’ gains. For large-scale power systems, this feature is illustrated with the use of time domain simulations, showing the dynamic behavior of the significant variables. The transient response is enhanced in terms of maximum overshoot and settling time. This is demonstrated using the deviation between the behavior of some important variables with StatCom, but without or with PSS. A B-Spline neural networks algorithm is used to define the best controllers’ gains to efficiently attenuate low frequency oscillations when a short circuit event is presented. This strategy avoids the parameters and power system model dependency; only a dataset of typical variable measurements is required to achieve the expected behavior. The inclusion of PSS and StatCom with positive interaction, enhances the dynamic performance of the system while illustrating the ability of the strategy in adding different controllers in only one design stage.

In this work, a survey is carried out on six MPPT algorithms which include conventional and artificial intelligence based approaches. Maximum Power Point Tracking (MPPT) algorithms are used in PV systems to extract the maximum power in varying climatic conditions. The following most popular MPPT techniques are being reviewed and studied: Hill Climbing (HC), Perturb and Observe (P&O), Incremental Conductance (INC), Open-Circuit Voltage (OCV), Short Circuit Current (SCC), and Fuzzy Logic Control (FLC). The algorithms are evaluated, analyzed, and interpreted using a Matlab-Simulink environment to show the performance and limitations of each algorithm

Voltage instability analysis in electric power system is one of the most important factors in order to maintain the equilibrium of the power system. A power system is said to be unstable if the system is not able to maintain the voltage at all buses in the system remain unchanged after the system is being subjected to a disturbance.The research work presented in this paper is about the analysis of voltage instability of electric power system by using voltage stability margin (VSM), load real power (P) margin, reactive power (Q) margin, reactive power-voltage (QV) and real power-voltage (PV) modal analysis. IEEE 30-bus system has been chosen as the power system. The load flow analysis are simulated by using Power World Simulator software version 16.

Fabrication And Characterization

Purpose The purpose of this research work is to harvest energy using the piezoelectric properties of ZnO nanowires (NW). Fabrication and characterization of the piezoelectric nanogenerator (NG), based on Al/ZnO/Au structure without using hosting layer, were done to harvest energy. The proposed method has full potential to harvest the cost-effective energy. Design/methodology/approach ZnO NW were fabricated between the thin layers of Al- and Au-coated substrates for the development of piezoelectric NG. To grow ZnO NW, ZnO seed layer was prepared on the Al-coated substrate, and then ZnO NW were grown by aqueous chemical growth method. Finally, Au top electrode was used to conclude the Al/ZnO/Au NG structure. The Al and Au electrodes were used to establish the ohmic and Schottky contacts with ZnO NW, respectively. Findings Surface morphology of the fabricated device was done by using scanning electron microscopy, and electrical characterization of the sample was performed with digital oscilloscope, picoammeter and voltmeter. The energy harvesting experiment was performed to excite the presented device. The fabricated piezoelectric-sensitive device revealed the maximum open circuit voltage up to 5 V and maximum short circuit current up to 30 nA, with a maximum power of 150 nW. Consequently, it was also shown that the output of the fabricated device was increased by applying the stress. The presented work will help for the openings to capture the mechanical energy from the surroundings to power up the nano/micro-devices. This research work shows that NGs have the competency to build the self-powered nanosystems. It has potential applications in biosensing and personal electronics. Originality/value The fabrication of simple and cost-effective piezoelectric NG is done with a structure of Al/ZnO/Au without using hosting layer. The presented method elucidates an efficient and cost-effective approach to harvest the mechanical energy from the native environment.
