In this paper, through the deployment of two-way interactive equipment and load control equipment, combined with the Internet of things, we design the automated demand response scheme based on Internet of things, according to different power consumption behavior model, it realizes the monitoring of electrical equipment, makes demand response control strategy to guide users to participate in power grid peak load shaving, and analyzes the change of the power using behavior and its influence to power grid load according to the collected data. So it can optimize the power using energy structure of end-user, improve energy utilization efficiency, save energy consumption, realize Automatic demand response, reduce the power grid peak valley load difference, and improve the efficiency of the power grid.
