Grey Wolf Algorithm in Coordinated Hydro and Wind Power Generation

风电随机波动给电网的功率平衡带来了困难,因此出现了弃风问题。为了减少风电功率波动对电力系统功率平衡的影响,可以实行风电水电协同运行。充分利用水电的调节能力和风电的能量,用水电厂来平抑风电场输出功率的波动,通过控制水电机组实现风电水电协同运行,使风水协同系统按照计划输出功率。为了实现风电水电协同运行和提高风水协同输出的平稳性,采用灰狼算法优化水轮机PID控制,使水电可以稳定地跟踪风电的变化,使风电与水电出力按照计划输出。仿真结果验证了控制方法的有效性。

Wind is stochastic that trouble the grid power balance and make wind curtailment occur.The wind power and hydropower could cooperate operation to reduce the influence of wind power fluctuation.Through making full use of the regulating ability of hydropower and wind energy,the coordinated operation of wind power and hydropower can be realized by controlling hydropower units,so that the wind and hydropower coordinating operation system will output according to the plan,stabilize the power system.To achieve the coordinated operation of wind power and hydropower and improve the stationarity of the coordinate output,the Grey Wolf algorithm was used to optimize the PID control of hydraulic turbine,to facilitate hydropower steadily track the change of wind power and make the output of wind power and hydropower output according to plan.The simulation results verified the effectiveness of the method.
