Optimization strategy for overhauling active distribution network electrochemical energy storage with participation of multi-type flexible resources
As an effective means for power systems to cope with new energy grid integration problems and achieve power balance,the operation and maintenance of electrochemical energy storage power plants is crucial,and it is urgent to formulate a reasonable overhaul plan.In order to improve the economy and reliability of the overhaul plan for electrochemical energy storage plants,an active distribution network energy storage plant overhaul strategy with the participation of multiple types of flexible resources is proposed.Firstly,a multi-type flexible resource operation model including mobile energy storage,emergency power supply vehicle and inverter air conditioning clusters was constructed to provide additional power support for the overhaul work;Secondly,based on the constraints of the active distribution grid system operation and the constraints of the overhaul plan of the energy storage equipment,a multi-objective optimization model for the overhaul of the electrochemical energy storage station was constructed,and the corresponding optimal overhaul plan was solved by the tolerant hierarchical sequential method;Finally,the simulation analysis is carried out based on the IEEE 33-node system.The results show that the proposed strategy balances the need for timely maintenance of equipment with the need for safe and economic operation of the power grid.
