熔盐线性菲涅尔光热-光伏一体化发电系统的智能功率协调控制OA

Solar thermal-photovoltaic integrated power generation systems suffer from high energy loss and costs,and the lack of bidirectional optical-electrical-thermal energy conversion capability,limiting the improvement of their practi⁃cality and energy efficiency.Aimed at these problems,a molten salt linear Fresnel(MSLF)solar thermal-photovoltaic integrated power generation system is constructed,coupling low-cost and energy-efficient MSLF solar-thermal genera⁃tion with photovoltaic generation and molten salt electric heating subsystems.This coupling establishes a bidirectional conversion pathway between electrical energy and thermal energy,thereby overcoming the application and energy effi⁃ciency bottlenecks of traditional systems.Based on this,an intelligent power coordinated control system is designed that employs strategies of self-learning enhanced model predictive control,multi-resource coordination,and safety opera⁃tion to enable precise and flexible conversion among optical,electrical and thermal energy,improving grid dispatch tracking capability and energy efficiency.Simulation results indicate that the proposed system reduces the power track⁃ing error by 78.53％ and improves economic efficiency by 10.80％,compared with traditional systems,which can pro⁃vide strong support for the large-scale application of integrated power generation systems.
