The Optimal Choice of Electrochemical Energy Storage Parameters

Abstract

The possibility of using energy storage in a power system is being highlighted increasingly often. Its operating mode or manner of use is called the “storage usage strategy”. One of them, program operation, was selected for this study. An algorithm of the supervisory control of storage for a chosen strategy is described. Simulation results are presented. The investor may face a dilemma of how to select parameters for the storage operated in a strategy. Based on the simulation results, technical and economic optimisation indicators were determined. A pattern of the selection of total storage capacity for the chosen strategy was developed, taking into account various types of electrochemical storage, with a fixed usable capacity. The considered optimisation problem is to establish a compromise between storage life and its effective use.
