Penetration of Hybrid Energy Systems in Power Grid with State-of-the-Art Control

Abstract

The Grid-Connected Hybrid System has more sophisticated and state-of-the-art control than stand-alone systems and show minimum fluctuation as compared to subsystem connected individually. This paper mainly emphasizes detailed simulation based on hybrid system PV-BESS-WECS by solving bottleneck problems such as power quality concern for the higher power system and control challenges associated with it. The control strategies and coordination schemes used for dc-dc boost converter rely on a local controller such as incremental conductance algorithm with maximum power point tracker, battery storage system with bidirectional converter control, and wind turbine based upon Type-III wind generator was implemented to meet the load demand while keeping into consideration stringent grid-code requirements. Moreover, static synchronous compensator was interconnected during normal grid operation at point of common coupling to reduce voltage flicker and harmonic currents. A hybrid energy system has been performed in the MATLAB/Simulink framework which verifies the performance and feasibility of the proposed scheme.
