输电阻塞本质上是输电容量的不足。传统的短期边际成本输电定价方法使网公司的收入严重不足 ,相应电价也不能给出充分反映输电容量不足的信号 ,而输电当量电价却有独特优势。在输电当量电价模型基础上 ,采用用户上报支付意愿的方法 ,建立了直接阻塞管理模型。该模型还可以在仅仅用电价调控阻塞无能为力的情况下合理削减负荷 ,同时又可获得充足而又合理的电网扩建资金 ,有利于输电网的投资扩容 ,从根本上缓解阻塞问题 ;通过用户上报支付意愿 ,引导用户参与阻塞管理。算例中将输电当量电价法与传统短期边际成本方法做了比较 ,并讨论了与支付意愿有关的市场特性。结果表明 ,该方法更合理、更有效 Transmission congestion is inherently a lack of transmission capacity. The traditional method of short-term marginal cost transmission pricing causes the net income of the net company to be seriously insufficient, and the corresponding price can not give a signal that fully reflects the shortage of transmission capacity. However, the transmission equivalent price has unique advantages. Based on the transmission equivalence price model, a direct congestion management model is established based on the user’s willingness to pay. The model can also cut down the load under the condition of powerlessness control alone, at the same time, it can obtain enough and reasonable power grid expansion funds, which is conducive to investment expansion of transmission network and fundamentally alleviate the congestion problem. Will, guide users to participate in obstruction management. In the example, the transmission equivalence price method is compared with the traditional short-term marginal cost method, and the market characteristics related to the willingness to pay are discussed. The results show that this method is more reasonable and effective
