计及动态碳排引导功率互济的多层次互联柔性配电网低碳调度OA

With the low-carbon transformation of power system,the study of the low-carbon performance of distribution network which is taken as a bridge between source and load is conducive to the low-carbon operation of the whole power system.In this paper,a low-carbon scheduling method for multi-level interconnected flexible distribution networks that takes into account the dynamic carbon emissions to guide power interconnection is proposed.First,a regional dynamic carbon emission limiting factor is formulated on the basis of the dynamic carbon emission factor of the external grid,and these two factors are combined to guide the power interconnection of each region in the flexible distribution net-work.Second,a carbon limitation mechanism is constructed to limit the negative impacts of carbon reduction benefits brought by power interconnection in each region during the time of wind and light deprivation.Finally,on the basis of the guiding characteristics of power interconnection,the guiding characteristics of the dynamic carbon emission factor of the external grid for energy storage and demand response within the distribution network are comprehensively taken into account,so that a low-carbon economic scheduling model of multi-level interconnected flexible distribution net-works is established.Simulation results verify that the proposed low-carbon economic scheduling strategy can accurately guide the low-carbon power interconnection of each region,prevent the occurrence of wind and light abandonment,and realize the low-carbon economic operation of distribution network.
