Hybrid Renewable Energy System

What is it about?

This paper presents a standalone hybrid renewable energy system (SHRES) to supply alternating current (AC) loads. The interfacing configuration of SHRES sources to the AC bus is discussed. The control strategies based on voltage and frequency (Vf) with droop concept for the stable source and active and reactive (PQ) power control concept for the energy sources are proposed for the SHRES’s stability, power quality and load sharing. The SHRES and the control strategies have been modeled in PSCAD/EMTDC software. Simulation results show the proposed control strategy is shown to be able to regulate the voltage and frequency at the common AC bus.
