Customer Nodal Cost Calculation using Voltage Sag Coordination Charts

전압 강하 협조 그래프(VSCC)를 이용한 수용가 모선 가격 계산

In this paper, supposed that can measure power quality of bus and can calculate this cost in case electric charges about customer are imposed by each bus. When reflected this in system planning, expected cost proposed following method through sample system. We calculated the nodal cost by OPF(optimal power flow) in system and the drop numbers that happen during year of loads utilizing VSCC. Also calculated BPQC using the disruption numbers. As a result, calculated bus total cost including power quality cost through case study.
