A review of frequency control of hybrid renewable energy system with hybrid control model

Abstract

This paper presents a review of a frequency control of hybrid renewable energy system (HRES) with hybrid control model. Stand alone and grid-connected hybrid renewable energy system (HRES) to supply AC masses. The configuration of the frequency control based HRESs and interfacing power converters for connecting the energy sources to the AC bus is lengthily elaborated. In this paper, the summary of the control concepts in an HRES and the application of the appropriate control schemes for system stabilization, effective injection of high-quality power and proper load sharing are discussed. The different approaches for HRES design and control strategies for power converters in the recently published literature are also briefly addressed. This paper specially addressed various control strategy in the hybrid renewable energy system.
