Multi-objective coordinated energy management method and system for optical storage integrated power station

Abstract

The application discloses a kind of multi-objective collaborative energy management methods and systems for light storage integrated power station, method includes: obtaining the real-time operation data of light storage integrated power station current detection period;Based on real-time operation data, the operating efficiency evaluation value of light storage integrated power station, energy storage device life attenuation evaluation value and power grid support ability evaluation value are calculated;Based on real-time calculation result, multi-objective collaborative optimization instruction is generated using dynamic priority strategy;Multi-objective collaborative optimization instruction is decomposed, and photovoltaic inverter output instruction, energy storage device charge-discharge power instruction and grid-connected power instruction are obtained, and light storage integrated power station is operated according to photovoltaic inverter output instruction, energy storage device charge-discharge power instruction and grid-connected power instruction.By constructing dynamic priority strategy, adaptive switching of multi-objective weight is realized, and problems such as equipment wear and tear intensification and power grid support lag caused by single-objective optimization are effectively solved.
