| Abstract: |
| Traditional centralized dispatch methods are unable to meet the needs of power system economic dispatch in the context of high-permeability distributed energy resource access. Distributed economic dispatch scheme has received more and more attention due to its characteristics of high reliability, strong scalability and uniform communication and computation burden. The research statuses of distributed economic dispatch methods at home and abroad are reviewed. The principle and application of consensus algorithm and the reason why it becomes the dominant algorithm of distributed economic dispatch are emphasized. The centralized and distributed economic dispatch system and the problem solving process are compared. The points of the distributed economic dispatch process are analyzed, and both advantages and disadvantages of the existing methods are reviewed. The problems to be solved in the study of distributed economic dispatch method are analyzed and the possible further research directions are proposed. |
