Low Carbon Optimal Dispatching of Microgrid Considering Demand Response

Abstract

With the increasing energy demand and environmental pollution, reducing carbon emissions and developing renewable energy are the key to solve low carbon economy operation of microgrid. To solve the above problems, an optimal dispatching model of microgrid based on carbon market and green certificate trade mechanism is proposed under the constraint of demand response. Firstly, considering the reward and penalty ladder carbon trading mechanism, a microgrid framework based on green certificate market is established, which increases the proportion of green electricity and reduces carbon emissions. Then, mobilizing the peak regulating potential, the load demand response strategy is proposed, which guides reasonably the users’ energy consumption and improves the system security. Finally, considering the advantages of low carbon characteristics, an optimal dispatching model of microgrid is established to minimize the comprehensive costs. The results of case analysis show that carbon emissions and the total cost of system is reduced by 2.81% and 1.73%, which verifies the feasibility and practicability of the proposed model.
