摘　　要：风光火打捆外送系统利用能源的互补性,通过控制器的协同作用实现能源平稳注入电网,在工业和民用方面具有广阔应用前景。针对风光火打捆外送系统并网产生的低频振荡问题,提出一种抑制低频振荡的控制器优化策略。首先,搭建风光火系统模型和控制器模型;其次,设计了增强型鲸鱼优化算法(EWOA);最后,利用EWOA对电力系统稳定器(PSS)和统一潮流控制器附加功率振荡阻尼器(UPFC-POD)参数进行优化。算例分析表明,协调参数后的控制器能充分利用其协调作用,有效提高系统多运行工况下阻尼比。Wind-photovoltaic-thermal-bundled(WPTB)power transmission system makes use of the complementarity of energy and realizes the smooth integration of the energy into the power grid through the synergy between controllers,which has broad application prospects in industrial and civil use.Aiming at the problem of low-frequency oscillation(LFO)generated by the integration of WPTB power transmission system,the paper proposes a controller optimization strategy to suppress LFO.Firstly,the wind-photovoltaic-thermal system model and controller model are built.Secondly,the enhanced whale optimization algorithm(EWOA)is designed.Finally,EWOA is used to optimize the parameters of power system stabilizer(PSS)and unified power flow controller-power oscillation damping(UPFC-POD).The case analysis shows that the controllers with coordinated parameters can make full use of the synergy between the controllers,and effectively improve the damping ratio of the system under multiple operation conditions.
