为提高风-光-水电联合系统的经济性,以联合系统发电收益最大为目标函数,综合考虑各类约束条件,建立了考虑光热储能的风-光-水电联合系统优化调度模型。采用Tent混沌映射和收敛因子非线性调整策略对灰狼优化算法进行改进,采用改进灰狼算法对联合系统优化调度模型进行求解。结果表明,加入光热储能电站后,联合系统出力波动性显著减小,单日发电收益提高34.47万元,经济效益提升显著,验证了模型的正确性和改进灰狼算法的优越性。

In order to improve the economy of wind light hydropower combined system,taking the maximum power generation income of the combined system as the objective function and comprehensively considering various constraints,an optimal operation model of wind light hydropower combined system considering solar thermal energy storage is established.Using Tent chaotic mapping and nonlinear adjustment strategy of convergence factor,the grey wolf optimization algorithm is improved to form an improved grey wolf optimization algorithm to solve the optimal operation model of the joint system.The results show that after addingthe joint system to the solar thermal energy storage power station,the output fluctuation of the joint system is significantly reduced,and the daily power generation income is increased by 344700 CNY,which proves that the economic benefit is significantly improved.The correctness of the model and the superiority of the improved grey wolf algorithm are verified.
