Bilateral contract is one of the major trading schemes in electricity markets， and certainly could also be employed in generation-rights trading. Up to now， the centrally matchmaking trading mode has dominated the generation-rights trading in practice， but bilateral contract is surely another feasible mechanism for consideration. Based on the successful experience in electricity market practices， it is believed that the combination of the centrally matchmaking trading mode and bilateral contract mode， i.e. creating a hybrid market， could lead to a better market operation for generation-rights trading. However， the employment of a hybrid market for generation-rights trading could result in some new problems for system dispatch. In case of congestion， how to curtail equally and reasonably between these two kinds of trading is especially an important issue to be investigated. Given this background， efforts have been made to develop coordinated congestion dispatching models in a hybrid generation-rights trading market. With the enforcement of a coordinated constraint， the two kinds of trading could be treated in a non-discriminatory way. The feature of the developed models is demonstrated with case studies of the IEEE one-area RTS 96-bus system.
