Control Design and Stability Analysis of an Energy Storage System in a DC Link for Industrial Pulsed Power Applications
Abstract
This paper analyzes an energy storage system (ESS) in a direct current (DC) link to mitigate the high power ratio. Furthermore, it examines how the ESS control architecture can be modelled to coordinate the interaction among the prosumers in the DC link so that the peak shaving target is achieved. First, the paper presents a simulation model of the ESS connected to the DC link. Then, the DC link supply of passive rectifier and active infeed converter are discussed separately with measured data. The inverter control system is simplified and integrated in the software framework. Peak shaving can be achieved by droop control or power control. After that, the paper presents a system configuration with communication via OPC UA for a potential forecast control strategy and energy management. The simulation shows the potential for optimized load management with a mid-sized ESS.
