Fault Ride Protection of the Motor-Generator Pair System for Renewable Energy Systems

Abstract

Nowadays, the world has reached a point when the integration of renewable energy sources like wind energy, solar energy, etc., with the country's electricity grid, will have a greater role when the global warming rate has reached a distressing rate in the world. Also, there will be problems while implementing the connection of wind turbines and any other renewable energy sources with the grid. One of the problems related to this is called ‘Fault ride through disturbances’ this work proposed asynchronous Motor and Generator Pair (MGP) system as a probable solution for the integration of renewable energy to recover inertia and improve network stability. This work analyses the Fault Ride briefly Through the scenario of wind energy conversion system (WECS) and solar system. This work establishes the Dynamic Voltage Restorer (DVR) configuration or management strategy. To compensate for power for each phase disjointedly, a closed-loop PI manage law is proposed in the d-q reference frame. The proposed technique provides fast response and effectual case recompense functions and runs a MATLAB/SIMULINK simulation of such type of Low Voltage Fault Ride through Scenario, as well as analyzing the results
