Multi-Energy Microgrid Optimization Operation Model Considering Waste Disposal and Multi-Source Coordinated Energy Storage

Aiming at the problem of urban waste reduction in the no waste city plan, the multi-energy microgrid operation problem raised by full renewable energy supply, this paper proposes a coordinated energy storage based on multiple energy sources and is highly compatible Multi-energy microgrid optimized operation model for waste treatment facilities. First, the energy conversion process of waste pyrolysis and gasification is studied, and the power, heat, and gas energy output characteristics model of the waste treatment facility and the power balance characteristic model of the multi-energy microgrid connected to it are established, based on this, the garbage treatment is proposed multi-source integrated coordinated energy storage system (WDM-CCS); Then, study the economic model of garbage disposal and multi-energy microgrid operation, With the goal of minimizing the overall operating cost and maximizing the amount of waste disposal, the multi-energy microgrid optimization operation model of WDM-CCS is established. Finally, based on the operational data of multi-energy microgrid and garbage disposal facilities in a certain area in Northeast China, a multi-energy microgrid simulation model based on WDM-CCS is established. The simulation results show that compared with the traditional multi-energy micro-grid, the multi-energy micro-grid using WDM-CCS not only has better regulation ability and higher regenerative energy consumption, and can effectively improve waste disposal capacity. © 2020, Electrical Technology Press Co.
