Power Quality Enhancement in Photovoltaic Solar Power Plant

Modern Power systems are equipped with green and renewable energy resources, one among them is Photovoltaic solar generating plants. This article is focused on developing the Solar Power plant model equipped with dc-dc boost converter controlled with MPPT algorithm with MATLAB code inbuilt in the Simulink Model and the Power Quality analysis of Solar plant connected to the AC Grid with DSTATCOM. MPPT algorithm is developed in order to obtain optimal power from PV cell at all loading conditions. Fast Fourier Transformation (FFT) analysis has been done for the entire system at each stage of the conversion. This book focused on the implementation of the DSTATCOM to minimize the harmonics in the proposed system. Pulse Width modulation is implemented for controlling three phase DSTATCOM and Simulink models have been developed for the case study with Solar generating plant connected to boost converter to increase the dc voltage to a higher level, and is given to DSTATCOM to obtained AC Power and it is connected to the grid through coupling transformer for feeding the loads. The FFT analysis have been performed and presented in the article, the results have been proven the fact that the power quality of the solar plant output voltage and current waveforms, improved enormously. This work focuses on implementation of the active filter to minimize the harmonics introduced by the 3-ph VSC into the system. The isolated PV solar system is feeding R and RL loads and injecting the harmonics into the system and passive filters have been designed and connected to the system and harmonics have been mitigated. Further the PV solar system is tied to the grid. THD is to be minimized using proper design of passive filters. Pulse Width modulation is implemented for controlling three phase five level H bridge inverter. Simulink models have been developed for isolated PV solar plants feeding both loads and Interconnected PV system with grid have been developed. FFT analysis has been performed to obtain THD, further the system is designed and simulated with power quality compensators in the system to minimize the harmonics.
