边际成本理论在输电网络电价中的应用

Application of Marginal Cost Theory to Transmission System Pricing

应用边际成本理论提出了一种新的输电网络电价方法。该方法将电价分成电力电价及电量电价两部分，并通过一个统一的运行模拟模型进行求解。该法不仅能为电网有效运行及良性发展提供正确的经济激励信号，而且具有计算及实施方便的优点。文中通过一个简单算例说明了所提方法的可行性。

A novel comprehensive price method for transmission system is presented.The proposed price is composed of two parts:power price and energy price,both are solved with a unified operation simulation model.This method can not only offer the correct economical incentives for transmission system operation and expansion,but also has advantages in computation and completing convenience.A simple example is given to demonstrate the validity of proposed method.
