计及电制氢设备特性的主动配电网分层配置与优化OA

Under the background of constructing new-type power systems,the rational configuration of distributed energy resources,energy storage systems,power-to-hydrogen(P2H)devices,and reactive power compensation equipment is a critical pathway to enhancing the economy,flexibility,and reliability of distribution networks.Aiming at the electricity-storage-hydrogen interaction system on the distribution network side,an optimization model with hierarchical configuration for distribution networks considering the characteristics of multiple types of equipment was proposed by establishing equivalent node power flow models for distributed energy resources such as wind and solar power,energy storage,and P2H devices.The upper-level model determined the site selection and capacity planning schemes for equipment such as distributed energy resources and energy storage with the objective of minimizing annual investment,construction,operation and maintenance costs.The lower level determined the operation strategies for distributed energy resources,energy storage,P2H devices,and static var compensators on typical days with the objective of optimizing voltage stability in the distribution network.Taking the IEEE 33-node system as an example,optimization analysis was conducted using an improved multi-objective particle swarm optimization algorithm.The simulation results showed that the addition of energy storage systems and the integration of equipment such as P2H devices reduced the system's annual economic costs by 21.17%,lowered the wind and solar power curtailment costs by 79.67%,and effectively enhanced the system voltage stability.
