Microgrid source-storage joint planning multi-strategy evolutionary game analysis method based on subject finite rational decision

Abstract

The invention provides a Microgrid source-storage joint planning multi-strategy evolutionary game analysis method based on subject finite rational decision. The method is characterized in that the method comprises the steps of establishing a multi-interest subject evolutionary game model, establishing an evolutionary game replicator dynamic equation, solving an evolution stabilization strategy, and solving an evolution stabilization strategy based on multi-strategy evolutionary games, the problems that benefit conflicts between micro-grid operators and power grid operators are difficult to balance in current micro-grid planning and a traditional game method assumes that participants are completely rational are solved. By adopting the method provided by the invention, the income between themicrogrid operator and the power grid operator can be effectively balanced, the renewable energy utilization rate in the microgrid is improved, and the power grid loss is reasonably reduced. The method has the advantages of being scientific, reasonable, high in applicability, good in effect, capable of improving the microgrid intelligent planning efficiency and balancing the benefit relationshipbetween different operators and the like.

Description

technical field [0001] The invention relates to the field of microgrid source-storage capacity planning, and is a multi-strategy evolutionary game analysis method for microgrid source-storage joint planning based on the subject's limited rational decision-making, which is applied to the microgrid distributed power supply (Distribution Generation, DG) and energy storage (Battery energy storage system, BESS) joint planning. Background technique [0002] In order to improve the utilization of renewable energy and meet the flexibility needs of small regional power supply, the regional microgrid system based on distributed generation has become a research hotspot. As a small power generation and distribution system including distributed power supply and energy storage system, microgrid effectively supplements the large power grid system, which can effectively improve the reliability of regional power supply and reduce the cost of long-distance transmission. Reasonable allocation...

AI Technical Summary

Problems solved by technology

The game method can effectively balance the complex economic relationship between different subjects, but the traditional game assumes that the participants are completely rational, so when analyzing the conflict of interest subjects, the solution is too ideal

In the application of evolutionary game in other fields, only two policy sets are used at most, and it is difficult to determine the influence of more decisions by users on the decision conclusion
