Innovative energy management system for energy storage systems of multiple-type with cascade utilization battery

Abstract

The proposed system provides an energy management method for various types of an energy storage system including cascade utilization battery. The method is used to receive, store and manage the relevant operating data from the energy storage battery and also randomly determine the energy distribution coefficient of the energy storage battery. According to the adaptive energy distribution method, the power value of the total distributed energy storage power to the cascade utilization energy is calculated and also the energy distribution coefficient of the energy storage battery in real time is adjusted. Finally, the corrected command value of the energy storage battery power is obtained as an output. The system can not only prevent overcharging and over-discharging of the energy storage system, but also maintain the good performance of the energy storage system. To realize the coordinated control and energy management of the battery power plant, we use multiple types, including conventional battery and cascade utilization power battery control purpose. The performance metrics, namely, real-time energy management, computational time and operating cost are employed for the experimental purpose. The simulation results show the superior performance of the proposed energy management system over other state-of-the-art methods.
