摘　　要：为了解决区域电力现货市场协调跨省区送受电优先计划和跨省区中长期交易体系等难题,使区域电力现货市场出清结果可真实反映事先核定的跨省区输电价格和网损率,提出了一种含跨省区输电网损偏差修正的区域电力现货市场出清模型。首先,以中国南方区域电力市场为例,分析了跨省区送受电交易主体和交易体系。其次,提出了一种同时考虑交易成分和物理潮流的网损偏差修正方法,并基于该方法构造了跨省区送受电物理潮流与交易成分相耦合的区域电力现货市场出清模型。最后,采用9节点系统和中国南方电网模拟系统开展仿真验证。仿真结果表明,采用所提的网损偏差修正方法和区域电力现货市场出清模型,可确保在满足系统安全运行约束的前提下,将跨省区输电价格和网损率反映在现货市场出清电价中,有效协调了跨省区送受电优先计划和跨省区中长期交易体系。In order to solve the problems of the regional electricity spot market to coordinate the priority plan of trans-provincial sending and receiving power and the trans-provincial medium-and long-term trading system,and to make sure that the clearing results of the regional electircity spot market can truly reflect the pre-authorized trans-provincial transmission price and the network loss rate,a clearing model for the regional electricity spot market with the deviation correction of network losses in the trans-provincial transmission grid is proposed.Firstly,taking the China southern regional electricity spot market as an example,the trans-provincial sending and receiving power trading entities and trading system are analyzed.Secondly,a deviation correction method of network losses considering both trading components and physical power flow is proposed,and based on this method,a clearing model for the regional electricity spot market with coupling of physical power flow and trading components is constructed.Finally,a 9-bus system and the China southern power grid simulation system are adopted to conduct simulation and verification.The simulation results show that the proposed deviation correction method and the clearing model for the regional electricity spot market can ensure that the trans-provincial transmission price and network loss rate can be reflected in the clearing price on the premise that the system safety operation constraints are satisfied.
