A Coordinated Approach for Frequency Control of Zero Emission Based Smart PV-Wind-Battery Power System

Power demand of isolated communities or islands primarily relies on heavy oil based diesel generator systems where these fossil fuel based power generators are not only costly but also create adverse effect on the environment. Photovoltaic generator system (PV system), wind energy conversion system (WECS) and battery energy storage system (BESS) are clean sources of alternative energy. These energy sources can be the alternative of diesel generator based power system for an isolated communities such as islands. However, both PV systems and WECSs are uncertain and fluctuating sources of energy causing power fluctuations and frequency deviations. This paper proposes a coordinated approach of the frequency control for a zero emission based small power system with renewable energy penetration. PV system, WECS and BESS have been utilized to control frequency of the proposed zero emission based power system. Efficacy of the proposed frequency control system is shown with simulations results.
