摘要：Faced with the deregulation of power grid in China, the traditional operation dispatch of system and the management of customers will change enormously. In the new environment, the power consumption of customers could be adjusted with the information and communication technology, which provide a new approach for system operator to maintain the power balance between supply and demand during contingencies. In China, thermostatically controlled loads (TCLs) account for a large proportion of power consumptions and have a great potential to provide regulating reserve for system. Therefore, a strategy for contingency management with TCLs is proposed in this paper to guarantee the reliable operation of power system. Firstly, the regulating capacity models of aggregated TCLs are proposed by the aggregation of the model for one individual TCL considering the customer behaviour and electric-thermal characteristics. What's more, an optimization model integrating the aggregated TCLs and conventional generators is proposed to determine the operation dispatch during contingencies. The proposed methods are validated using the modified IEEE 30-bus system.
