摘要/Abstract

摘要： 受电网建设与风电场建设不协调、外送通道输送能力不足等因素影响,风电场弃风问题日益严峻,且短期内无法得到有效解决。结合中国大规模风电基地开发建设特点,建立了一种基于超短期功率预测的限出力条件下的风电场集群有功功率优化分配方法。该方法将限出力条件下的风电场集群有功出力最大化、线损最小化作为目标函数,将系统安全、风电场输出功率、风电机组频繁启停、低预测功率作为约束条件,并计及了联络线上有功功率损耗以及超短期有功功率预测误差的影响。以中国西北地区某风电场集群进行的算例分析验证了方法的有效性和可行性。

Abstract: Due to the inconsistent development of power grid and wind power farm, as well as insufficient power transmission capability, wind-abandon problem is becoming increasingly serious in China, and no effective solution can be found in a short time. With consideration of large scale wind power base construction in China, a method is proposed in this paper for wind farm cluster active power optimal dispatch under output restriction condition, which is based on the ultra short-term wind power forecasting. In this method, the active power maximization and the line loss minimization are assumed as the objective functions on the condition of output restriction, with power system security, output power of wind farm, frequent turn-on and-off of wind turbines, and the low forecasted power as the function constrains. In addition, the active power loss and short term active power forecasting error are also considered. A case study of a wind farm cluster located in the north-west of China has verified the effectiveness and feasibility of this method.

Key words: output-restricted, optimal dispatch, active power, wind farm cluster
