| 摘 要： | 分析了储能系统对含风电的机组组合问题的影响,为提高电力系统运行的灵活性和降低风电波动性对机组组合问题的影响,在含风电的机组组合问题中引入储能系统.将含风电和储能系统的机组组合问题描述为混合整数凸规划形式,采用分支定界结合内点法进行求解.采用最优优先搜索和深度优先搜索相结合的搜索策略提高分支定界的搜索效率.通过10机系统算例分析,表明储能系统的引入可明显地降低风电波动性对机组组合问题的不利影响.

| Abstract: | This paper presents a simulation method that can assess the impact of energy storage system(ESS) on the unit commitment(UC) problem with volatile wind power.In order to achieve the higher system flexibility and reduce the impact of volatility of wind power,ESS is incorporated into the UC problem with wind power.The UC problem with wind power and ESS is formulated as the mixed-integer convex program,which is optimized by branch and bound combined with interior point method.During the branch and bound process... |
