摘要
提出了一种在现有电网条件和电源结构下提高接纳风电能力的优化调度方法。该方法根据风电功率预测数据、电网负荷预测数据和省间联络线计划,协调优化安排常规机组,预留风电出力空间,然后计及电网安全稳定等约束条件,计算并网风电场有功出力的安全区域,根据不同风电场有功出力对区域电网安全影响的敏感性高低,安排风电场发电计划,尽可能多地接纳风电。现场运行数据验证了所提出的风电优化调度方法的有效性。
In this paper,an optimized wind power dispatching method is proposed to improve the power grid’s acceptable wind power capacity based on the current network structure and power source construction. In the method proposed,the normal generator sets are arranged based on the wind power prediction,the load forecast and the interconnection tie plan,so the space for the wind power is reserved in advance. The secure area for the wind power plant’s active power is determined considering security constraints of the power grid. Then the safety area sequence of wind power plants is decided by the area stability sensibility v.s. the active power. Thus,the wind power can be accepted as more as possible.This method is verified by the operation data.
