摘　　要：传统的风电接纳能力计算方法没有考虑实际电网的调度运行方式,缺乏普遍的实用性。在考虑电网调峰约束的前提下,对影响风电接纳能力的重要边界条件进行敏感性分析,依托D5000智能电网调度技术支持系统,读取电网短时开机方式的运行数据。提出省级电网风电接纳能力的计算原理与算法,求解出接纳能力指标值,进而构建协调电网调度计划制定与接纳风电能力的优化调度模型,实现了常规电源与风电的协调运行,降低风电功率对电网运行的冲击,使计算得出的结果能够更加准确地反映电网实际接纳风电能力。现场运行数据验证了所提出的风电接纳能力计算方法的有效性。Traditional calculation method of the ability to wind acceptance, without considering the scheduling operation mode of actual power grid, is lack of common practicability. Under the premise of considering peak regulation constraints, this paper makes sensitivity analysis on the important boundary conditions which affect the ability to wind acceptance, and relying on the D5000 technical support system, reads operation data of the generator mode in power grid. The theory and method are proposed, by which wind acceptance index of provincial grid can be calculated, and then the optimization scheduling model which coordinates power grid scheduling plan with acceptance ability of wind power is constructed, thus realizing the coordinated operation of the conventional power and wind power, reducing the impact of wind power to the grid, and making the calculated results more accurately reflect the actual acceptance of wind power. The run data proves the calculation method of the ability to wind acceptance is effective.
