Complementary Planning of Hydro-wind-photovoltaic Systems Considering Hydropower Unit Vibration Zones
随着风电、光伏的大规模并网,电力系统面临灵活调节能力不足的挑战.水电运行灵活,通过与风光协同规划、互补运行,能有效平抑新能源出力波动,保障并网消纳.水风光协同规划的关键之一在于对水电灵活调节能力进行准确建模,其中振动区约束不容忽略.为此,提出了考虑水电振动区的水风光协同规划模型.该模型首先利用组合数学技术将水电机组振动区合成为电站振动区;然后,综合考虑振动区约束及梯级水力联系、水力发电方程等各项约束,实现对水电系统的准确建模;最后,耦合水电系统与新能源、联络线等相关运行约束形成水风光协同规划模型,并采用混合整数线性规划进行求解.以乌江流域某水风光互补系统为例,验证所提模型的有效性.
With the large-scale integration of wind power and photovoltaic,the power system is facing the flexibility challenge.As a flexible power source,hydropower can smooth the new energy output fluctuations and improve the energy accommodation through complementary planning of hydro-wind-photovoltaic power(CPHWP).In CPHWP,one of the keys is to accurately model the hydropower flexibility,in which the constraints of vibration zones cannot be ignored.Therefore,a model for CPHWP considering the impacts of vibration zones is proposed.In the model,the vibration zones of hydropower unit are firstly converted into the vibration zones of hydropower plant by combinatorial mathematics techniques.Then,considering the constraints of vibration zones,cascade hydraulic connections,hydropower generation equations,and other constraints,the accurate modeling of hydropower system is realized.Finally,the proposed model is formed by coupling the hydropower system,new energy system,tie lines and other related operational constraints,which can be solved by using mixed-integer linear programming.Case studies in a hydro-wind-photovoltaic system of Wujiang River are conducted to verify the effectiveness of the proposed model.
