Integrated Energy Collaborative Optimal Dispatch Considering Energy Flexible Building in Smart grid

Abstract

Based on the energy Internet framework, considering energy flexible building in smart grid, an integrated energy collaborative optimal dispatch is proposed. Firstly, the energy usage characteristics are studied from the perspective of the user demand, the flexible energy is divided into transferable energy, reducible energy and convertible energy, mathematical models are established according to these loads respectively, and the economic benefit is analyzed. Secondly, a thermal resistance model is constructed according to the thermal properties of the building to analyze the relationship between cold/heat power and human comfort. Finally, considering the human comfort and flexible energy building, the maximum operating revenue of integrated energy service providers is taken as the objective function, and the results of the park-level comprehensive energy collaborative optimization scheduling are obtained. The results show that the proposed model can improve economic efficiency and promote local consumption of new energy sources.
