基于交易曲线的电量分割模型及电价方案设计

当前国内跨省区中长期电力市场主要采用固定电价的结算机制,但是无法发挥电力市场的调节作用。为解决固定电价机制的弊端,根据合约电量曲线的实际执行情况,提出了以交易曲线为依据的电量分割方法。按照曲线外电量的发生时段和电量规模,提出了高峰及低谷曲线外电量的3种不同定价机制。通过算例按照该机制进行曲线外价格及交易费用的测算,定量说明了不同定价模式下偏差电量规模对结算价格的影响,从而达到了引导市场主体自觉按照交易约定曲线履行合约的目的。

Power Quantity Division Model and Electricity Price Scheme Design Based on Transaction Curve

The fixed electricity price mechanism has been adopted in the medium-long trans-provincial electricity market in China,but it is unable to play the regulation role of the electricity market.To solve the shortcomings of the fixed price mechanism,the principle of electricity-dividing according to the trading agreement curve and the execution curve are proposed,and the mechanism of time-sharing price settlement is analyzed.According to the occurrence period of the external power of the curve and the power scale,three different pricing mechanisms for the external power of the peak and valley curves are proposed.Finally,the calculation cases of the extra-curve price and transaction cost of the mechanism are carried out,which quantitatively explain the influence of the deviation power scale on the settlement price under different pricing modes,and achieve the purpose of guiding the market entity to consciously perform the contract according to the curve of the transaction agreement.
