计及碳减排分摊的配电网分布式储能集群配置方法OA北大核心CSTPCD

Under the background of the gradual establishment of the"carbon emission"market,aiming at the mismatch between the absorption capacity and growth rate of the system caused by a large number of distributed renewable energy accessed to the distribution network,this paper proposes an energy storage cluster partition method that considers the allocation of carbon emission reduction income among different subjects.First,all nodes are divided into several cluster regions based on the electrical distance and its power and load characteristics.Next,according to the characteristics of the new power system,this paper improves the calculation method of node carbon emission flow rate,and further proposes the influence model of cluster energy storage on the carbon emission flow of the distribution network,which can accurately calculate the carbon emission reduction apportionment of energy storage to each user based on the energy usage,and the corresponding carbon emission reduction apportionment income.Then,this paper proposes a distribution network distributed energy storage cluster configuration model with carbon emission reduction allocation,and the energy storage configuration is carried out for each cluster with the goal of minimizing energy storage life cycle cost and maximizing benefits such as carbon emission reduction.Finally,based on a simulation example of the IEEE 33 node distribution network,this paper verifies the correctness of the improved carbon flow calculation method and the rationality and economy of the cluster energy storage configuration method.
