Load Profile Analysis For Commercial Buildings Microgrids Under Demand Response

In electricity market, the analysis of different micro grid users' consumption behavior considering demand response is of great significance for large scale DG coupling, local consumption of new energy, energy-saving and emission-reduction. The analysis of load profile directly affects the economic efficiency of operation. In this paper, we have studied on historical load data of user-side commercial microgrid in Hangzhou region, Zhejiang province, China. In order to correctly discuss the difference of load characteristics between the micro-grid and large power system, three types of indices are selected to analyze the load characteristics of this region and main factors which could lead to load variation are researched. Under time-of-use price environment, cross-time demand response models based on price elasticity matrix are constructed for simulating the load variation of commercial users in microgrid before and after demand response.
