Capacity and Cost Evaluation of Demand Response in the Rural Light Industry

The rural light industrial load is an important regional resource that could interact with the power grid and participate in demand response. Productive loads account for the majority, with the characteristics of aggregation, need for human assistance, and single electrical equipment. Exploiting the schedulable potential of productive loads could provide demand response services for power systems. This paper establishes a model considering characteristics of productive loads, including time constraints, production characteristics constraints, and so on. Taking liquor-brewing industry as an example, capacity and cost evaluation of demand response method for light industry clusters is proposed. Based on the actual load data of several townships in Guizhou, China, cases were conducted to verify that liquor-brewing industry clusters could provide the capacity of demand response. As capacity increases, the cost of participating in demand response increases, and even the opportunity cost caused by production losses needs to be considered. The proposed evaluation method could guide users' demand response behavior.
