Abstract

Based on various system simulations, this paper discusses combining renewable energy systems (RES) and battery energy storage systems using DC grids. The concept comprises the mitigaton of effects induced by RES volatility and provide reliable power injection which allows the provision of system services. To demonstrate the technical potential and fields of application of these DC grids in short and long time frames,
a DC collector grid and an MVDC link are investigated in the RMS and EMT domain, respectively. The results show that the proposed DC grids are able to provide plannable power infeed into existing AC grid structures. Only slight deviations depending on the control strategy and the converter model detail occur during extrem RES power gradients. After the validation of the technical potential, different challenges of these DC grid applications are discussed.
