摘要
随着风电穿透功率的增加,电力系统的运行风险不断提高,传统的确定性旋转备用容量配置方法存在较大的局限性。在研究风电出力概率分布特点的基础上,建立了风电机组可靠性模型;计及风电出力预测偏差、负荷预测偏差、常规发电机组故障停运等不确定因素,兼顾系统运行的经济性和可靠性,提出了考虑大规模风电并网的电力系统旋转备用容量优化模型。通过算例分析验证了该模型的合理性和有效性,对含风电场的电力系统运行具有一定的参考价值。
With the increase of wind power penetration, the operating risk of power system is more serious. The traditional method to determine the capacity of spinning reserve has limitation. A wind turbine reliability model based on studying the timing and autocorrelation of wind velocity is put forward. Next the forecast error of wind power and load, including the outage of conventional generators is taken into account and a model of optimal spinning reserve capacity of power system considering wind power is established in order to balance both economy and reliability. Simulation results prove the rationality and effectiveness of this model. It has some reference value to the power system operation with wind power.
