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.
