摘要
应用边际成本理论提出了一种新的输电定价方法。该方法在目标函数中考虑了电网的固定成本，形成了以系统发、输电费用最小为优化条件的二次规划模型。通过求解这个模型，可求得每条支路的电价。文中又提出采用潮流跟踪法确定用户对电网的使用程度，从而完成了输电费用在用户之间的分配。该方法既保留了边际成本定价中的经济信息，又有利于电网的年收支平衡。通过算例说明了该方法的可行性。
A novel transmission pricing method based on marginal cost theory is presented. This method includes fixed cost in generation and transmission cost optimization function and a quadratic programming model is proposed. Price of every line can be obtained by solving this model. The electricity-tracing method is proposed to calculate line power flow that each custom should share in, then transmission cost allocation is finished. This method keeps economic information in marginal cost method and benefits to make both ends meet. An example is given to demonstrate the validity of proposed method.
