This paper presents a novel method of congestion adaptability management in electricity power markets based on risk theory. Probability distribution of ambient conditions around transmission line is taken into account. Impact of overload of transmission line is also included. Instead of the traditional deterministic current or power constraint, the risk constraint is used for transmission line thermal security. An optimal power flow model is built based on the risk constraint. Primal-Dual Interior Point Method is adopted to solve the problem. The results provide a useful decision-making assistance for the independent system operator to relief transmission congestion. A test power system is used to illustrate the efficiency of the proposed method.
