Voltage Regulation in Microcontroller fed Bidirectional Converter Based on Genetic Algorithm using PV

Abstract

The grid connected Bi-directional Converter based on Photo-Voltaic (PV) uses a genetic algorithm (GA) to reduce the settling time of DC link voltage, and to increase voltage gain. The BDC meets load demand and regulates the energy flow from various sources. Problems in the existing system have Total Harmonic Distortion (THD), DC link voltage and its settling time is high. This paper presents a microcontroller based voltage regulation in bidirectional converter using solar power generation. The solar, battery and grid has used to generate the power, to improve output power quality, a Sliding Mode Controller (SMC) in the inverter is used. To improve the voltage regulation operation using genetic algorithm based PID controller. The bidirectional converter and inverter utilize solar, battery and grid power generation hybrid. The battery functions as a charge based on two-way converter operation and electricity generation modes. The power quality improvement in bidirectional converter has power factor correction, harmonics elimination and voltage regulation at AC mains. This paper proposes the analysis of genetic based PID control a process that effectively reduces the bidirectional converter harmonics; this aim is attained and shown in both MATLAB/Simulink and experimental results.
