摘要
以确定性方式考虑电网N-0或N-1预想事故来制定调度计划,而忽略输电元件故障概率,难免得到保守或冒进方案,影响电网运行条件下的风电接纳。为此,考虑输电元件故障概率,构建了协调电网静态安全与接纳风电能力的概率优化调度模型。通过不同风况下的风电场预测申报功率场景分析,对比电网确定性与概率性安全下的风电最大容许上网功率,论证了该模型能够以风险均衡方式有效协调电网静态安全与接纳风电能力,从而提升电力系统调度计划制定的科学性。
Considering grid transmission component N-0 or N-1 contingency by deterministic way to make dispatching plan, while ignoring their failure probability, the dispatching plan will be inevitably conservative or aggressive in wind power accommodation during grid operating condition. Therefore, the transmission component contingency probability is taken into consideration, and a probabilistic optimal dispatching model of balancing grid security and wind power accommodation capability is established. Through the analysis of wind farm reported forecasting power scenarios under different wind energy conditions, comparing the grid maximum accepting wind power of deterministic and probabilistic network security, the recommended model is demonstrated effectively to coordinate the power grid static security and wind power accommodate capability by the risk balanced mode, so the power system dispatching plan can be more scientific.
