Advanced Control Strategies for the Grid Integration of Wind Energy System Employed with Battery Units

Abstract

There is a global wide reception for the renewable energy sectors owing to the failure phase of conventional systems in the modern society. The concern may arise because of the growing demands and obviously the setbacks created by the conventional form of power generations. Among other form of non-conventional energy sources, wind technology receives a better acceptance next to the solar photovoltaic energy generation. Battery units (BUs) are considered to be the mains of the renewable power extraction due to the unreliability of resources and the similar design structure of the BUs are unsuitable for wide applications. This particular research certainly deals about the hybrid BU technology and enhancement of its relevant characteristics to be employed for grid integration of wind energy systems respectively. The bidirectional converter study is performed, alongside grid and source side converters with appropriate control strategies and their performances are analyzed in detail. Ultra capacitor studies are imposed to suppress the power fluctuations across the DC link and allowed momentary charging of BUs based on the requirements. The state of charging (SoC) of BUs is monitored and appropriate controllers are perhaps used to manage the generation and utilization. The idea pertaining to the discussions are executed through the PSCAD simulation platform and the results are validated.
