摘　　要：随着中国电力市场化改革的不断推进,部分省市将在传统发电计划的基础上逐步引入市场化交易手段,在此背景下,如何构建计划电量与市场交易电量并存下的日发电计划模型是需要解决的问题。综合考虑了现有发电计划模式,构建计划电量分解与纳什均衡下市场交易电量分配相结合的日发电计划模型,研究不同市场化开放程度对日发电计划的影响,分别从经济性和安全性两个方面对所制定的日发电计划进行了评估。通过对中国华东地区某省级电网进行算例仿真,分析不同市场化交易电量对全系统发电成本和电力不足期望的影响,验证所提模型的有效性。With the continuous promotion of China’s electricity market-oriented reform, some provinces and cities will gradually introduce market-oriented trading means on the basis of traditional generation schedule. In this context, how to establish the daily generation schedule model considering planned and trading electricity is an urgent problem to be solved. In this paper, a model of daily generation schedule that combines planned electricity decomposition and Nash equilibrium of market trading electricity is established, in which the existing mode of generation schedule is taken into account. By means of solving the model, the daily generation plan was evaluated in two aspects of economy and security, by studying the impact of different market openness. An example simulation of a provincial power grid in East China is given to analyze the impacts of different market trading electricity proportion on the generation cost and power shortage expectation of the whole system, and verify rationality and effectiveness of the proposed model.
