Inverter Control Strategy for PMSG Based WECS with Battery for a Standalone System

Abstract

In a standalone wind energy conversion system, variation in load affects the power quality (voltage and frequency
at PCC) due to the presence of power electronic devices which introduces harmonics in the system. Moreover,
wind speed variation is also one of the reason for voltage fluctuation. In this paper the proposed inverter control
strategy is able to mitigate the harmonics in the system and improves the power quality. The proposed system
contains a battery with a controller which helps the system to integrate it with other renewable energy system such
as solar PV system, Fuel cell system, etc. The system is modelled in MATLAB Simulink and the simulation
results supports the system for further integration with other renewable energy system.
