To address the challenge faced by existing developers in distributed photovoltaic and storage planning

specifically the difficulty in adequately considering the impacts of network reconfiguration

storage operation strategies

and active power reduction on the configuration results of optical storage under the drive of different stakeholders

an optimization method for the joint configuration of photovoltaic and storage systems under multi-stakeholder interaction is proposed. First

a joint configuration framework is constructed under the interaction between developers and distribution network operators(DNO)

revealing the decision variables and interaction mechanisms of each stakeholder. Secondly

a joint configuration model for photovoltaic and storage systems under the interaction between developers and DNO is established.In the developer planning stage

the distributed photovoltaic capacity and storage capacity are determined by maximizing the developer′s annual investment and operational revenue.In the developer operation stage

the storage operation strategy is decided by maximizing the developer′s annual operational revenue.In the DNO operation stage

the network reconfiguration

active power curtailment

and power purchase and sale with developers and the upstream grid are decided by maximizing the supply revenue.Then

the planning and operation models of developers are coupled

and the KKT(Karush-Kuhn-Tucker)conditions and the big-M method are used to transform the developer′s planning and operation models into constraints of the DNO model for solution.Finally

the effectiveness and economic feasibility of the proposed photovoltaic storage joint configuration method are validated through a case study in a specific region.
