To enhance the economic and environmental benefits of microgrids
a bi-level optimization method considering integrated demand response uncertainty and carbon-green certificate collaborative trading is proposed. Firstly
based on consumer psychology theory
the electrical
thermal
gas
and cooling loads are modeled separately to construct an integrated demand response uncertainty model. Secondly
a stepped carbon trading mechanism
green certificate trading
mechanism and quota update mechanism are introduced to establish a carbon-green certificate collaborative trading model. Finally
a bi-level optimization model for the microgrid is developed to derive the optimal operation strategy. Simulation results demonstrate that considering integrated demand response effectively improves the average load rate of each load type and significantly reduces the average peak-valley difference. Furthermore
the introduction of stepped carbon-green certificate trading and quota update mechanisms can reduce the total operating cost of the microgrid while decreasing its carbon emissions.
