摘　　要：Renewable energy is becoming more popular due to its benefits for both economic and environmental reasons.Therefore,having a fault free system will enhance efficiency and proper delivery of power.This paper presents the design,modelling and simulation of a Synchronverter,analyzing its fault and response of the system during integration.A synchronous frequency regulator for grid connection is proposed to improve quick recovery,power quality enhancement and good system performance after a fault occurrence.The swing equation provides the inertia and the damping for stability,swift system integration of photovoltaic energy to the grid and an overall effective performance.The effectiveness of the proposed model was simulated in MATLAB/Simulink to analyze the system’s response during and after a fault occurrence and photovoltaic integration comparing load change at different times.Simulation results and analysis are presented to validate proposed controller.
