Research On Prosumer-park Integrated Energy Supplier Collaborative Planning Model

Integrated energy utilization technology is currently a research hotspot in the global energy field,and plays an important role in the consumption of renewable energy,optimization of energy structure and improvement of the overall efficiency of energy systems.The park is one of the main applications of integrated energy utilization technology.In the future,the park’s integrated energy system will form a new type of energy supply and transaction system based on the park integrated energy suppliers and taking prosumers as important players.This paper conducts some studies on the collaborative planning model of prosumer-park integrated energy supplier.The main contents are as follows:(1)A collaborative planning model of prosumer-integrated energy supplier under the purchase and sale prices of electricity are set.Aiming at the two major stakeholders,prosumer and integrated energy supplier in the park,their respective optimization planning models are proposed.On this basis,according to the mechanism of mutual influence,a collaborative planning model is proposed to achieve a win-win situation for both the prosumer and the integrated energy supplier of the park.(2)A collaborative planning model of prosumer-integrated energy supplier considering the price game is proposed.Aiming at the five major factors in the game problem,the time-of-use electricity price model for large power grids,the electricity purchase and sale price model,and the investment of return rate model for integrated energy suppliers in the park are proposed.On this basis,according to the definition of Stackelberg game equilibrium,a master-slave game model of collaborative planning is proposed,which effectively improves the economic benefits of prosumer and integrated energy supplier in the park.Through the analysis of numerical examples,the effectiveness of the proposed model is verified.It provides a useful reference for constructing a reasonable prosumer-integrated energy supplier collaborative planning scheme.
