Abstract

Nash equilibrium is usually used to investigate a generator's strategic bidding in electricity markets. Some literatures show that the transmission constraints may induce no pure strategy equilibrium and make it hard to find the equilibrium. Using an analytical approach to find a mixed strategy Nash equilibrium in electricity market with transmission constraints, we analyze the influence of transmission capacity on the mixed strategy Nash equilibrium. Finally, a simple numerical example is provided to support the claims of this paper.

경쟁적 전력시장에서 발전회사의 전략적 행위를 분석하기 위해서 일반적으로 내쉬균형(Nash equilibrium) 이론이 널리 사용되고 있다. 기존 연구에 의하면 송전제약이 있는 전력시장에서는 최적반응의 불연속으로 인해 순수전략내 쉬균형이 존재하지 않게 되고, 이때는 혼합전략 내쉬균형이 전력시장의 균형이 된다. 본 논문에서는 송전제약이 있는 2-지역 전력시장에서 혼합전략 내쉬균형을 유도하고, 송전용량이 혼합전략 내쉬균형에 미치는 영향을 해석하였다.
