Focusing on the coordination of interests between the energy side and the load side in microgrids
this paper proposes a dynamic energy pricing mechanism that incorporates carbon emissions and demand response characteristics. Firstly
a dynamic pricing model considering carbon emissions as well as the demand response of electrical and thermal loads is established
and a combined operational mode of wind-solar power generation and carbon capture is put forward. Secondly
a bi-level optimization model involving multiple stakeholders is constructed
where the upper level consists of microgrid energy operators and the lower level includes load aggregators and electric vehicle charging stations. Subsequently
to address the issue of searching for the optimal solution in the bi-level model
a joint optimal discrimination mechanism for the bi-level model is introduced. Finally
the CPLEX solver is employed to iteratively solve the microgrid bi-level optimization model
and the case study results verify the effectiveness of the proposed dynamic energy pricing method and the combined wind-solar power generation-carbon capture operation mode in enhancing the economic efficiency and low-carbon performance of the microgrid system.
