The research on the economic load dispatch of grid-connected microgrid considering the carbon emissions trading

Microgrid technology can provide an effective technical approach for the new energy and renewable energy and the carbon emissions trading can provide favorable conditions for the grid-connected Microgrid operating economically. As a result, it establishs the optimal operation model of grid-connected Microgrid with taking into account the carbon emissions trading in the paper. It proposes a optimal method to minimize the total economy costs including costs of power losses, operations costs, capital, environmental costs, Start-up/Shut-down Costs, operation and maintenance costs in the microgrid. To validate the performance of the proposed method, it adopts composite adaptive global artificial fish algorithm and analyze with the typical microgrid. The simulation results show that the composite adaptive global artificial fish swarm algorithm is applicable to solve the optimal operation of grid-connected Microgrid, and the carbon emissions trading can significantly improve the the economy of microgrid.
