Source-Load Matching Analysis and Optimal Planning of Wind-Solar-Thermal Coupled System Considering Renewable Energy Ramps
Wind,photovoltaic,and thermal power generation can form a coupled system through the same grid-connected point,which is a high coordination and low-carbon approach of renewable energy and flexible regulating power source at generation side in northern China.By considering renewable energy ramps and source-load matching analysis,this paper studies the optimal capacity planning of a wind-solar-thermal coupled system to provide reference for coupled system planning.First,the operation model and the uncertainty method of coupled system are briefly described.Then,considering the wind-solar complementary,ramp events,and critical load characteristics,relevant indices are selected and proposed for source-load matching evaluation.After that,considering the constraints of source-load characteristics,matching,and cost,an optimal capacity planning model of wind-solar-thermal coupled system is established.Finally,based on the actual data in Liaoning Province,a case study is conducted to acquire the optimal capacity of the wind and solar generation in the area,and the interaction between the source-load relevant indices and the planning results is analyzed,which provides reference and suggestion for the optimal capacity planning of renewable energy generation.
