  • Purpose of the electric power system planning and operation is to supply the electric energy to customers continuously and economically. With the mutual exclusive laws of nature between reliability and economic, finding the meeting point is very important but not easy. Commonly the probabilistic reliability indices of the electric power systems are represented with negatively. And the effectiveness of FACTS on the probabilistic reliability could not be reflected with common methods. In this paper, a method to evaluate the probabilistic arrival power at each load point is presented. With this new proposed method, probabilistic reserve margin at load points can be calculated and which can be used with positive reliability index also. Using the P-V analysis, the voltage stability is considered in reliability evaluation. It is expected that the proposed method will be useful expecially in reliability evaluation of electric power system which has voltage restriction.

  • 전력시장의 환경변화와 전력소비자들의 다양성 그리고 전력소비자들의 다양한 요구를 수용하기 위해서 확률론적 전력공급 신뢰도 평가에 대한 사회적 요구가 커지고 있다. 과거 전력계통의 신뢰도 평가는 발전계통만을 대상으로 하는 HLI에서의 신뢰도평가였으나 최근 송전망을 포함한 복합전력계통의 신뢰도 평가에 대한 관심과 연구가 진행되고 있다. 복합전력계통의 신뢰도 평가에서는 일반적으로 각 부하지점별 공급지장 가능성 등을 시뮬레이션을 통해 산정한다. 본 연구에서는 각 부하지점에서의 공급가능용량을 확률론적으로 평가하는 방법을 보인다.
