Access-Oriented Energy Storage Configuration Method to StabilizeFluctuation of Pulsed Load

Abstract

It is necessary to minimize the negative influence caused by pulsed load on microgrid. By analyzing impulse load characteristic, access-oriented energy storage, especially super capacitor, turned out to be suitable energy storage to stabilize this huge fluctuation. This paper presents an optimal configuration method of energy storage system (ESS) in microgrid, which is based on the result of spectrum analysis of sample data of pulsed load. This method both takes into consideration the stability of system and energy storage cost at the same time. The effectiveness of this approach was verified by case analysis of a typical steel plant with pulsed load using MATLAB software.
