Congestion Management of Generation Rights Trade Based on Energy Conservation

At present,in the research on generation right trade model based on energy conservation the attention is mainly paid to the variation of coal consumption before and after the trade,and the influence of generation right trade on network loss in power system is not adequately considered.When congestion occurs in power system due to generation right trade therefore the number of trade pairs should be reduced,in general the congestion management is adopted and the influence of network loss is less considered,thus the energy conservation effects of generation right trade pairs cannot be overall judged.A generation right conservation model,in which the energy conservation is taken as the object,is built,and in the built model the network loss of power system and coal consumption are synthetically considered to effectively guide the implement of generation right trade and ensure optimal energy conservation of power system after the completion of the trade.When some transmission lines are congested due to the generation right trade,using the proposed model for congestion management can achieve better energy conservation effect.The effectiveness of the proposed model in the selection of trade pairs and management of congestion is verified by simulation results of IEEE 14-bus system.
