A Multi-Objective Approach for Low-carbon Economic Dispatch With Carbon Capture Power Plants and Demand Response

This paper proposes a multi-objective approach for low-carbon economic dispatch with carbon capture power plants (CCPPs) and demand response (DR). First, brief dispatching model of CCPPs is presented. The operation mechanism of CCPPs and DR for different objectives is analyzed. Then, the multi-objective low carbon economic dispatch model with CCPPs and DR is proposed. The objectives include minimizing the bidding cost of conventional power units and wind power, minimizing carbon emissions, maximizing utilized wind power and minimizing DR cost. The weighting coefficients of the objectives are calculated by analytic hierarchy process (AHP). The optimization model is recast as a mixed integer linear programming (MILP) formulation and solved by CPLEX. Finally, numerical results performed on the modified PJM 5-bus system verify the feasibility and effectiveness of the developed model by comparing to single objective cases.
