Abstract

The unified power flow controller(UPFC) is one of the most effective devices in the FACTS family. This paper concerns about a filtering technique for reducing the computer calculation to determine the optimal location of UPFC in a power system. The sensitivities of the power generation cost for UPFC control parameters are evaluated. This technique requires that only one optimal power flow is run to get UPFC sensitivities for all possible transmission lines. To find out a optimal locating of a single UPFC in power system, an ideal transformer model which consists of a complex turns ratio and a variable shunt admittance was used. In this model, the UPFC control variables do not depend on UPFC input and output currents and voltages. The sensitivity method was tested on a 5-bus system derived from the IEEE 14-bus system and IEEE 14-bus system to establish its effectiveness.

일체형 조류제어기인 UPFC는 FACTS 기기중 가장 효과적인 기기 중 하나이다. 본 논문에서는 전력시스템에서 UPFC의 최적위치를 결정하는 데 필요한 컴퓨터의 계산을 줄이는 방법에 대하여 기술한다. 이를 위해 UPFC 제어 변수들과 관련된 발전 비용의 민감도가 평가되었다. 모든 송전선로의 UPFC 민감도를 얻기 위해 단지 한 번의 최적조류제어만으로 해결하였다. 전력시스템에서 UPFC의 최적 위치를 알아내기 위해 여러 권선비와 가변 션트 어드미턴스로 구성된 이상변압기 모델을 사용하였다. 이 모델에서 UPFC 제어 변수들은 UPFC 입 출력의 전류와 전압에 대해서 종속되지 않는다. 민감도 방법은 그의 효율성을 파악하기 위해 IEEE 14 모선에서 파생된 5 모선시스템과 IEEE 14 모선시스템을 대상으로 실험하였다.
