Cost-based Unit Commitment Considering Demand-side Resources with Harmony Search Algorithm
نویسنده
چکیده
Integrated resource planning has been performed by electric companies, because of its multifarious benefits in power system operation. Demand Response Resources (DRRs) can be used as a virtual demand side power plant. DRRs are clustered to IncentiveBased Programs (IBPs) and Time-Based Rate Programs (TBRPs). Precise modeling of DRRs helps the system operator to investigate the impact of responsive loads on the power system operation. A multi attribute decision making (MADM) methodology is presented to select a program which reflects Independent System Operator (ISO) perspectives. The cost-based unit commitment (UC) problem with an improved formulation is also introduced to investigate the impacts of DRRs on generation scheduling. The UC problem as a crucial challenge of system operator is solved using harmony search algorithm to determine the role of demand response in generation scheduling. The numerical studies are conducted on the conventional ten-unit test system to confirm the capability of the proposed structure.
