摘　　要：太阳能光热发电和风力发电的输出功率存在较大的随机性和波动性,考虑两者在时间上的输出功率互补性,充分利用光热发电的储热装置可形成光热和风能联合运行发电系统。提出了一种太阳能光热与风能互补发电的功率协调控制策略,从运行机理入手,在传统光热电站运行约束的基础上,提出简化后具有良好适应性的优化模型。根据联合系统输出功率波动方差最小和联合系统并网效益最大化构建多目标函数,采用法线边界交叉法的多目标优化协调控制光热发电和风力发电的输出功率。最后利用Matlab软件对所提模型及协调控制策略进行了仿真验证,结果表明,提出的优化策略可提高太阳能光热和风能的利用率和减小并网功率的波动,同时增加了光热风能联合发电系统经的济效益。A coordination control strategy for solar thermal and wind energy complementary power generation is proposed, starting from the running mechanism and on the basis of traditional optical thermal power station, the optimi- zation model with good adaptability is put forward. Multi - objective function is constructed according to the minimum variance of output power fluctuation and the maximization of grid connected system, and the output power of solar ther- mal power and wind power generation is coordinated and controlled by multi - objective optimization by using normal boundary crossing method. Finally, the proposed model and the coordinated control strategy are simulated and verified by using Matlab software,the results show that the proposed optimization strategy can improve the utilization rate of solar thermal and wind energy and reduce the fluctuation of grid connected power, at the same time, it can increase the economic benefit of the combined power generation system.
