An experimental study of demand response effect of a multi-building portfolio

Abstract

Demand response (DR) can effectively balance the contradiction between power supply and demand and promote the integration of renewable energy into the grid by changing the end user s power demand curve through control strategies. Relevant research has begun to pay attention to the important role of building users in demand response. The current experimental research on building demand response is only focused on single building, because the experiment of simultaneous demand response for multiple buildings is restricted by various external factors. However, the load of a single building is relatively small compared to the entire power grid, so the building needs to be involved in the demand response project in the form of a building group. This paper reports on an experimental research on the demand response effect of a building group composed of 10 office buildings, based on the Shanghai demand response pilot experiment. Firstly, the basic information of each building of the building group is introduced, and the scheduling process of the demand response experiment of the buildings is demonstrated; Secondly, the demand response baseline method used in this paper is detailed; this is followed by analyzing the demand response effect of each building and the building group on the day of the demand response experiment. The experimental results revealed that the average load reduction rate of the entire building group during the demand response period was about 8.44%, and each building had a relatively obvious load reduction.
