摘　　要：提出了一种基于机会约束规划的风电并网系统的有功优化潮流模型和算法。引入了表示风电场发电功率和母线负荷的随机变量,以概率的形式描述约束条件(如线路潮流、节点电压、旋转备用以及稳态频率偏移等)。开发了基于遗传算法和随机模拟技术的计算程序。在IEEE 30节点系统上的测试结果验证了文中所提方法的可行性。An algorithm for calculating optimal active power flow based on chance-constrained programming for wind power integrated system is proposed. The randomvariables are introduced to represent wind farm outputs and buses loads. Acco rdingly, the constraints like branch power flow, bus voltage, spinning reserve and steady frequencydeviation are expressed by means of probability. To solve the problem, a calculation program implementing geneticalgorithm and stochastic simulation are developed, the testresults on IEEE30 system demonstrate the feasibility of the proposed model and algorithm.
