考虑垃圾处理与调峰需求的可持续化城市多能源系统规划

A Sustainable Development Multi-energy System Planning Method Incorporating the Demand of Waste Disposal and Peak Shaving

随着"垃圾围城"的日益加剧及城市能源体系中多种能源形式间相互融合的不断深入,垃圾处理设施供能与多能源系统间的相互影响和作用越来越成为城市能源系统规划所需考虑的重点问题之一。针对计及能源化利用型废物处理设施的城市多能源系统规划问题,该文研究废物处理设施的能源供需特性及其调峰潜力,提出垃圾焚烧电厂和污水制气设施参与电网气网调峰策略,构建可持续性多能源系统规划模型。最后参考东北某市的实际能源与垃圾堆存量数据,建立可持续化城市多能源系统规划仿真模型,仿真结果及分析表明,该文提出的多能源系统规划模型可有效降低城市多能源系统规划成本,实现垃圾处理能力、垃圾供能与调峰需求间的高效协调。

With the situation that "cities besieged by waste" becomes aggravating and the intermingle of multiple energy forms in urban energy system grows, the interaction between waste disposal facilities energy supply and multi-energy system has become one of the key issues to be considered in urban energy system planning. To address the problem of urban multi-energy system planning concerning the supply and demand characteristics of waste disposal facilities,this paper proposed a joint peak shaving strategy with waste incineration power plant and sewage gasification facilities by the research of waste disposal facilities energy supply and demand characteristics and its potential for peak shaving.Meanwhile, a sustainable development multi-energy system planning model was established. Furthermore, based on the actual waste stockpile and energy data of a city in Northeast China, a sustainable development multi-energy system planning simulation model was established. The case analysis results show that the multi-energy system planning model proposed in this paper can reduce the planning cost of urban multi-energy system effectively, and realize the efficient coordination among waste disposal capacity, waste energy supply and peak shaving demand as well.
