如何有效的消纳大规模风电已成为制约我国风电快速发展的瓶颈之一，通过对柔性负荷进行控制并参与调峰是解决电力系统消纳风电和灵活配置备用容量的有效方法。分析风水火耦合电力系统中柔性负荷、风电等包含的随机因素在时空维度的无二义性描述；利用纳什博弈理论，考虑柔性负荷、随机风电、备用容量之间动态耦合关系，构建考虑对柔性负荷进行控制的耦合电力系统不确定性经济调度模型；运用"异轨同效"不确定性分析方法，推求不确定性模型的多重最优调度轨迹解集，形成调度决策的轨迹区间；最终通过仿真模型，论证最优调度轨迹区间的合理性和有效性。预期研究成果：可中断负荷及需方发电等典型柔性负荷参与调峰的风水火耦合电力系统不确定性经济调度模型；不确定性经济调度模型的准多重调度轨迹解推求方法；最优经济调度轨迹区间估计方法。研究成果可为风水火耦合电力系统备用电源的灵活优化配置提供理论依据，也可为经济调度决策的实施提供新的参考。

How to effectively consume large-scaled wind power has become one of the main bottlenecks of its fast development in our country. By controlling the flexible loads and participating in the peak load regulation, it can be the effective method of solving the problems of consuming wind power and flexible spare capacity configuration, this project will research into the economic dispatching key problems of wind-hydro-thermo coupled power system considering the peak flexible load regulation. From the linked relevance of all kinds of wind-hydro-thermo coupled power system random factors in time, space and time-space, we will analyze unambiguous expressive methods of the random factors involved in flexible loads and wind-powered electricity generation; use Nash game theory and consider the dynamic relationships among flexible loads, random wind-powered electricity generation and spare capacity, to construct the uncertain economic dispatching model of wind-hydro-thermo coupled power system with flexible loads; use the uncertain analysis method of "equifinality for different tracks" to get the best multiple track solution sets of uncertain model; finally through the simulation model to demonstrate the rationality and validity of the best dispatching track interval. Expected research results include: the uncertain economic dispatching model of wind-hydro-thermo coupled power system with main flexible load (including the interruptible load and generation power from the demand side) participated in; the methods of obtaining the prepared multiple dispatching tracks of uncertain economic dispatching model; the estimation method of optimal economic dispatching track interval. The research results can offer theory basis for flexible configuration optimization of spare power in wind-hydro-thermo coupled power system, and also can be used for the implementation of economic operation decisions to provide new choices.
