Cyber Physical System Based Energy Storage Optimal Configuration Strategy for Serving Multitype Loads

Résumé fourni par la source

At present, multi-source data of power system are faced with challenges such as insufficient acquisition accuracy and weak real-time performance. Cyber physical system is widely used in power system because it can provide technical support for real-time acquisition and collaborative processing of various data. Based on this, this paper proposes a cyber physical system based energy storage optimal configuration strategy to solve the problems of increased load fluctuation and peak-valley difference caused by new energy grid connection. Firstly, relying on the smart meters and sensors of the cyber physical system to realize the real-time high-precision data fusion of multiple types of power loads. Secondly, adopting the analytic hierarchy process method to establish a multi-dimensional comprehensive evaluation index system to assess the suitability of deploying energy storage for typical users and the preferred scheme. Finally, integrating the optimization results into the optimal dispatch model before the day of the user’s side to quantitatively analyze the benefits of peak shaving and valley filling and the effect of electricity cost reduction. The results show that this method can support the optimal configuration and economically optimal decisions of energy storage system.
