Abstract

The growth of renewable energy sources such as photovoltaic and wind power generation requires more reserve capacity to maintain supply-demand balance. This paper proposes a novel battery utilization method for assist of Load Frequency Control (LFC) by compensating the lack of generation rate for LFC served by thermal power plants. In the proposed method, the battery output is driven by excess component of LFC signal over the generation rate. In order to check the performance of proposed method, a comparison study has been done with a conventional method. When the generation rate is high, frequency fluctuation is not suppressed in proposed method since LFC units respond to LFC signal quickly and the battery hardly supplies reserve capacity. On the other hand, when the generation rate is low, frequency fluctuation is suppressed in proposed method. This is because LFC signal exceeds the generation rate and the battery provides with reserve capacity which is not served by thermal power plants. As a conclusion, the proposed method is adaptable for the total generation rate of LFC units and useful for suppressing the deterioration of frequency stability when the total generation rate of power system is relatively reduced by large penetration of renewable energy sources.
