Load Frequency Control for Renewable Energy Sources for Isolated Power System

This paper proposes the load frequency control method using model predictive control for isolated power system without thermal generator. Two control approaches are presented for generation and demand sides to achieve the generation/load balance and hence damp frequency fluctuations. First, five model predictive controllers are designed for wind power generator, photovoltaic generator, storage battery, fuel cell, and seawater electrolyzer to control their output power. Moreover, real-time pricing scheme is utility modify the controllable loads according to the value of frequency error.
