Abstract—This paper presents a real – time simulation of distribution system with distributed generation – DGs, Step voltage regulation (SVR) and battery energy storage systems (BESSs) using Real Time Digital Simulation (RTDS). The simulation models of a DG and a Nickel – Metal Hydride battery are developed as RSCAD user defined model. The control schemes of DGs and BESSs to show the impacts of DGs to local voltages and BESS to accommodate the variation of DG power output are proposed and implemented as a function block in the RSCAD platform. Difficulties of the system implementation in RTDS are also discussed and solutions are provided. Finally, the simulation results are given out to verify the correctness of the control schemes.
Index Terms—RTDS, distributed energy resource, battery energy resource, voltage control, user defined model.
