Application of a Battery Energy Storage System to Reduce Fluctuations in the Power Output of a Wind Farm Integrated into the Power System

This article focuses on the application of a battery storage system in order to reduce fluctuations in the power output of a wind farm integrated into the power system. The article shows the development of an algorithm that allows determining the power and capacity of the battery energy storage system to ensure a decrease in power output fluctuations, taking into account the limitations related to the peculiarities of the wind farm and energy storage operations. The developed algorithm was applied to a model of a real electrical network including wind farms. At the end of the article, a comparative analysis of the results obtained using the developed algorithm against the results obtained using the algorithm based on low frequencies was carried out.
