垃圾能源利用与城市多能源系统协同优化模型

With the promotion of urban multi-energy system and the expansion of energy supply scale of waste disposal facilities. Considering the coordinated optimization of waste resourceful with urban multi-energy system, which is one of the important ways to improve waste disposal capacity and resource utilization level and the comprehensive energy supply efficiency. The waste disposal system is equivalent to a waste resourceful energy supply system(WRESS) in this paper, and a collaborative optimization model between multi-energy system and multi-energy storage system and waste resourceful energy supply system is established. Firstly, a waste resourceful energy supply model is established by the research of the relationship between the refuse output, the maximum permitted stock, the corresponding energy supply types and characteristics in a certain time scale. Then, in allusion to the relationship between the regulation characteristics of waste resourceful energy and the coordination of multi-energy system and multi-energy storage system, a collaborative optimization model with the lowest total operation and regulation cost of multi-energy system and waste resourceful energy supply system is established. Finally, based on the actual waste disposal and multi energy operation data of a city in China, through three different scenarios of the numerical example to verify the effectiveness of the proposed model. The optimal simulation results show that the model can improve the waste disposal ability, meanwhile it can also reduce the operation cost of multi energy system and enhance the system regulation.
