| 摘 要： | 由风电预测不精确导致的随机性给安全约束机组组合和经济调度等带来新的挑战,尤其当考虑多风电场并网时,在确定性机组组合问题上表现良好的混合整数规划方法将陷入困境。文中通过引入发电机功率分布因子,并用基于极限场景集的场景法取代基于蒙特卡洛仿真的场景法,在计算时间和计算精度2个方面进行了改善。经过修改的IEEE118节点系统算例证明了在多风电场并网时,所述方法能更快地获得对风电随机性适应力更强的机组组合方案。

| Abstract: | Wind power generation brings new challenges to the security-constrained unit commitment(SCUC)and security-constrained economic dispatch due to its randomness.Especially when multiple wind farms are taken into consideration,mixed integer programming method which is good at dealing with deterministic SCUC problems doesn't work.This paper introduces generalized generation distribution factors and replaces the Monte Carlo simulation with extreme scenarios method,improving the calculation time and precision.The ... |
