LVDC 배전망의 PV와 BESS 모델링과 제어기 설계

Abstract

In this paper, the modeling and controller of PV and BESS, which are the core components of LVDC distribution network used for Gochang testbed, are designed and its performance is verified by simulation using PSCAD software. The simulation results show the modeling and dynamic behavior of PV and BESS system controllers. In LVDC distribution and DC microgrid, we think that this technology can be contributed not only based on customer practical use but also to the fault analysis, protection solution plan, and short circuit capacity calculation of DC circuit breaker.
