The development of smart grid provides the necessary technical support for power customers to take an active part in the regulation of power grid operation. A load control strategy scheme is presented based on multi-agent system aiming at commercial customers’ electrical response behavior in the smart grid environment. It designs a multi-agent control system containing multi-type of electrical equipment with power using ability as well as an interactive coordination mechanism. With reference to the characteristics of commercial power customers and to highlight commercial customers’ requirement on overall electricity comfort level

an aggregating load agent based on the existing multi-agent control system structure of residential customers is incorporated. A hotel commercial customer is taken as an example. And according to the operation characteristics of various types of electrical equipment

corresponding load response models are developed. Electric load priority is determined with the interval number ranking method based on real-time information about various types of electric equipment. The load control mode for the purpose of optimizing the comfort of commercial customers’ power utilization is created. Through case analysis

the features and rationality of the proposed model and method are brought out. This work is supported by National Natural Science Foundation of China (No. 51307019
