“…The study using the feeder model from Trinidad described earlier found that voltages dropped below acceptable limits at several feeder nodes when EV penetrations of as little as 5% were implemented [15]. Voltages were already very close to lower limits before any EVs were connected, a state which may be common in island and remote systems due to grid design and operation considerations.…”

Electric vehicles (EVs) represent an important socio-economic development opportunity for islands and remote locations because they can lead to reduced fuel imports, electricity storage, grid services, and environmental and health benefits. This paper presents an overview of opportunities, challenges, and examples of EVs in islands and remote power systems, and is meant to provide background to researchers, utilities, energy offices, and other stakeholders interested in the impacts of electrification of transportation. The impact of uncontrolled EV charging on the electric grid operation is discussed, as well as several mitigation strategies. Of particular importance in many islands and remote systems is taking advantage of local resources by combining renewable energy and EV charging. Policy and economic issues are presented, with emphasis on the need for an overarching energy policy to guide the strategies for EVs growth. The key conclusion of this paper is that an orderly transition to EVs, one that maximizes benefits while addressing the challenges, requires careful analysis and comprehensive planning.

“…KEPCO, Powertech Lab, and Yonsei Univ. jointly developed RTHS combining the RTS and TSA program because there are needs of testing replicas in the KEPCO advanced real-time simulation laboratory to investigate the future power system issues [2][3][4][5][6]. Figure 4 shows the configuration of RTHS.…”

“…In the Korean power system, three HVDCs and eleven FACTSs are in operation, four HVDCs are under construction, and two HVDCs and seven FACTSs are under planning [1]. Power electronics applications are located close to each other in the Korean power system, and concerns about interaction with adjacent network dynamics among the equipment have increased [1][2][3][4][5][6][7][8]. The hardware-in-the-loop tests of the power electronics equipment controller are required to demonstrate the equipment performance Real-time Hybrid Simulator (RTHS) is a co-simulation tool that synthesizes RTS with transient stability analysis (TSA) tool to perform detailed real-time simulation of a large power system [2][3][4][5].…”

This paper presents the hardware-in-the-loop simulation for dynamic performance test (HILS-DPT) of power electronic equipment replicas using a real-time hybrid simulator (RTHS). The authors developed the procedure of HILS-DPT, and as an actual case example, the results of HILS-DPT of Static VAR Compensator (SVC) replica using RTHS is presented. RTHS is a co-simulation tool that synthesizes real-time simulator (RTS) with transient stability program to perform real-time dynamic simulation of a large power system. As power electronics applications have been increasing, the electric utilities have performed HILS-DPT of the power electronics equipment to validate the performance and investigate interactions. Because inspection tests are limited in their ability to validate its impact on the power system during various contingencies, all power electronics equipment newly installed in the Korean power system should take HILS-DPT using large-scale RTS with replicas since 2018. Although large-scaled RTS offers an accuracy improvement, it requires lots of hardware resources, time, and effort to model and simulate the equipment and power systems. Therefore, the authors performed SVC HILS-DPT using RTHS, and the result of the first practical application of RTHS present feasibility comparing the result of HILS-DPT using large-scale RTS. The authors will discuss the test results and share lessons learned from the industrial experience of HILS-DPT using RTHS.
