摘　　要：为了评估电力系统中各发用电主体的成本及效益,需要对经济调度问题的博弈论均衡点开展研究与分析。随着新能源机组的大量接入以及用户绿色用电意识逐步提升,电力系统的发、用双侧均呈现新特征。首先,新能源机组的低边际成本特征、系统运行风险防控需求和用户侧的绿电需求都将对经济调度问题的数学形式产生影响。同时,传统解析方式在求解非线性均衡问题时也面临变量多和求解难等问题。为解决上述难题,首先提出了考虑绿电生产与消纳的电力系统风险防控经济调度数学模型,然后提出了基于最优响应法的博弈论均衡求解算法。通过算例分析,评估了可再生能源产消情况下的经济调度问题博弈论均衡情况,并对电力系统发电侧的投资规划提出了相关建议。To evaluate the costs and benefits of each power generation and consumption entity in the power system,it is necessary to analyze the game theory equilibrium point of the economic dispatch problem.With the massive integration of renewable energy units and the gradual improvement of users'awareness of green power consumption,both the generation and consumption sides of the power system are showing new characteristics.First of all,the low marginal cost characteristics of renewable energy units,the need for risk prevention and control of system operation,and users'demand for green power will all have an impact on the mathematical form of the economic dispatch problem.At the same time,traditional analytical methods also face problems such as numerous variables and difficulty in solving nonlinear equilibrium problems.In order to solve these problems,this paper first proposes an economic dispatch mathematical model for risk prevention and control of the power system considering green power generation and consumption and then puts forward a game theory equilibrium solution algorithm based on the optimal response method.Through case analysis,the game theory equilibrium situation of the economic dispatch problem under the generation and consumption of renewable energy is evaluated,and relevant suggestions are put forward for investment planning on the power generation side of the power system.
