Abstract

Transmission congestion is one of the key factors to local market power in competitive electricity markets. Financial transmission rights provide the financia] protection to their holders by paying back the congestion rent. A variety researches have shown that the existing trading mechanisms on transmission right can exacerbate market power. This paper proposes an alternative methodology in mitigating the local market power using the Contingent Transmission Rights on the locational marginal pricing scheme. The proposed methodology was demonstrated with the Optimal Power Flow.

경쟁적 전력시장에서, 송전혼잡은 지역적 시장지배력의 핵심 요인들 중 하나이다. 재무적 송전권을 구매한 시장 참여자는 그들이 지불한 혼잡 세를 돌려받음으로써 재무적 보호를 받을 수 있다. 하지만 많은 연구에서, 이러한 송전권이 오히려 시장지배력을 강화시킴을 보였다. 따라서 본 논문은 새로운 개념의 송전권인 Contingent Transmission Rights을 이용해 지역적 시장지배력을 완화시키는 것이 목적이다. 본 논문은 각 모선의 한계가격 (Locational Marginal Pricing LMP)을 기반으로 한 모선별 가격제도(Nodal Pricing)와 최적조류계산(Optimal Power Flow)를 이용해 사례연구를 수행하였다.
