可中断负荷(interruptible load,IL)作为用户参与电力市场的一种方式,最直接的影响是为供电公司提供另外一种可供选择的备用资源,在这种环境下,供电可靠性成本的内容也发生了变化,相应的可靠性电价计算模型也应有所调整。首先给出可中断负荷参与备用市场下可靠性电价定价流程,在此基础上量化了IL由于减少系统备用风险购电成本和电网投资改造风险成本而产生的经济效益,最后根据我国国情给出了可靠性电价的定价模型。算例分析表明,可中断负荷参与备用市场可为供电公司节约大量的可靠性投资成本,使其规避高购电电价和高投资的市场风险,进而降低用户支付的可靠性电价。
Interruptible load (IL), as a way for users to participate in the electricity market, has the most direct impact on providing power supply companies with an alternative backup resource. In this environment, the content of the reliability cost of power supply Also changed, the corresponding reliability of electricity price calculation model should be adjusted. First of all, we give the pricing process of interruptible load to participate in the reliability pricing of electricity in the reserve market. On the basis of this, I quantify the economic benefits that IL can generate due to the reduction of the cost of system backup risk and the risk of investment in transforming the power grid. Finally, according to our national conditions, Pricing Model of Reliability Price. The case study shows that interruptible load participation in the reserve market can save a great deal of reliability investment cost for power supply companies, avoid the market risk of high purchase price and high investment, and reduce the reliability price paid by users.
