Abstract

In order to improve the low-carbon economy of the distribution system, this paper first constructs the collaborative optimization scheduling framework of multi microgrid shared energy storage system. At the same time, in order to realize the flexible adjustment and fine characterization of emission reduction incentives on the basis of fully considering the supply-demand relationship of the carbon trading market, a refined carbon trading cost calculation method based on the dynamic carbon price and carbon quota supply-demand relationship is proposed; Then, in order to improve the timeliness of power decision-making in the real-time phase of the multi microgrid shared energy storage system and enhance the ability of the decision-making model to perceive the time-series information of wind and solar output with uncertain factors, a reinforcement learning algorithm combining short-term and long-term memory network and multi-agent near end strategy optimization method is proposed; Finally, in IEEE 33 bus system, the improvement effect of the proposed model and method on the low-carbon operation ability, operation economy and decision timeliness of the system is verified by simulation.
