Battery state of charge based algorithm for optimal wind farm power management

Abstract

Battery being an important prospect for energy storage for various applications, we need to use it economically taking battery health into consideration. Taking it in the context of wind farm power generation and management, whenever the forecasting power estimates are higher than the actual wind power, the deficit is supplied through the batteries. In the case of higher actual wind power than the forecasted power, we charge the batteries. This paper focuses on how we should charge and discharge the batteries so that we can decrease the number of storage elements required without harming their effective life. An economic study is presented on how to opt for a suitable methodology to balance the penalty with preferred wind forecasting schemes.
