摘要:

针对负荷密集区源荷侧协调平衡调度问题,建立了考虑需求响应的负荷密集区分布式综合能源系统,耦合了储能系统进行能量互补,构建了数学模型。提出基于经济性能、能耗性能、环境性能3方面的系统评价指标,建立了考虑系统经济、能耗、环境的多目标优化模型,利用层次分析法确定各指标间的权重关系,将综合性能作为整个系统的优化决策目标。建立了包含办公、酒店、住宅、商场4类建筑的负荷密集区建筑模型,分别对4类建筑进行逐月累计负荷模拟。此外,分析对比了考虑需求响应前后的负荷密集区容量配置及性能指标的优化情况。最后,对负荷密集区考虑需求响应前后的逐月建筑能力平衡调度进行分析。结果表明:无论是否考虑需求响应,负荷密集区整体设置一套供能系统时的系统性能指标均优于4类建筑分别单独设置供能系统并叠加的性能。

Abstract:

To coordinative and balanced schedule resources on source and load side in a load intensive area,a distributed integrated energy system considering demand response and coupled with an energy storage system to supplement power supply is established,and the mathematical model for this system is constructed. The system evaluation indexes are divided into economy,energy consumption and environmental protection indexes, and a multi-objective optimization model is established considering the three types of indicators above. The weights of these indexes are determined by Analytic Hierarchy Process (AHP),and the comprehensive performance index is derived and taken as the optimization objective of the system. The building models in a load-intensive area include models for office buildings,hotels,residential buildings and shopping malls,and the monthly cumulative loads of the four types of buildings are simulated. In addition,the capacity configuration and performance index of the load-intensive area before and after taking demand response into consideration are compared,and monthly balanced scheduling capacity of buildings in the load-intensive area before and after considering demand response is analyzed. The results show that, with or without taking demand response into consideration,the performance of the system taking an integrated energy supply system is better than that taking independent energy supply systems for the four types of buildings separately.
