摘　　要：合理制定分时电价和补偿价格,根据电量电价弹性系数建立了一种电力需求响应模型。该模型利用价格信号将负荷高峰时段的部分用电量转移到负荷低谷时段,实现了削峰填谷。根据该模型,提出了一种新的阻塞管理方法。该方法利用节点边际电价选取参与阻塞管理的负荷节点,被选取负荷节点根据多时段下的电力需求响应模型进行负荷转移,同时调节发电机出力,实现从发电侧和需求侧同时进行阻塞管理。IEEE 30节点系统仿真计算结果表明,该方法能够有效缓解阻塞、平抑电价、减少运行费用,具有更好的经济性。To draft rational time-of-use （TOU） power price and the price to compensate consumers, based on the elastic coefficient of electric quantity vs. electricity price a power demand response model is built. Using price signal, this model transfers a part of electricity consumption in peak period to valley period to implement peak load shifting. Based on the proposed model, a new congestion management method is proposed： by use of nodal marginal price, the load buses participating congestion management are chosen, and according to power demand response model for multi time intervals the load transferring is performed at chosen buses, and the generation unit output is adjusted to implement congestion management at generation-side and demand-side simultaneously. Simulation show that the proposed results of IEEE 30-bus system method can effectively mitigate congestion, keep prices stable and reduce operating cost
