Abstract Transmission congestion management becomes a major issue in power system operation in the electricity market environment. In the widely employed hybrid electricity markets with pool and bilateral-contract trade included, tight coupling exists between these two kinds of trade as both of them are implemented in the same system. Therefore, how to effectively coordinate the congestion dispatch between them is a very important problem. Given this background, a generalized model for determining the uniform market clearing price and a new coordinated congestion dispatching model based on efficacy coefficient are presented. In addition, the curtailed generation of bilateral contracts is allowed to be re-dispatched in the pool market in the proposed dispatching model, which would be helpful for decreasing the purchasing cost of the pool demands. Results of case studies of IEEE One-Area RTS-96 system demonstrate the main features of the proposed model and method.

Key words： Electricity markets pool markets bilateral contracts congestion management efficacy coefficient
