Complementary Planning of Hydro-wind-photovoltaic Systems Considering Hydropower Unit Vibration Zones
摘要
Abstract
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.关键词
