Investigation of Market-Based Demand Response Impacts on Security-Constrained Preventive Maintenance Scheduling

In recent years, load management (LM) programs have been contemplated as a crucial option in all energy policy decisions. Under deregulation, the scope of LM programs has been considerably expanded to include demand response (DR) programs. Here, the market-based DR programs are regarded as a virtual resource for reserve provision. Basically, demand-side reserve affects handling and controlling of power systems ranging from short-term to long-term scheduling. Preventive maintenance scheduling (PMS) of generating units is addressed as a long-term scheduling in power system studies, which is affected by DR programs. In this paper, a new structure for security-constrained PMS associated with DR programs is suggested. In order to scrutinize the economic- and environmental-driven measures of DR programs, a new linearized formulation of cost-and-emission-based preventive maintenance problem is presented. Here, the proposed framework is structured as a mixed-integer programming problem and solved using a CPLEX solver. This model would schedule reserves provided by DR providers, maintenance scheme, and commitment status of generating units. Values of energy and reserves over the scheduling time horizon are also simultaneously determined in this paper. The IEEE Reliability Test System is utilized to demonstrate the effectiveness of the proposed structure.
