Abstract

The invention discloses a distributed transaction method for multiple virtual power plants and load aggregators. The method comprises the following steps: S1, a market signal initialization stage; S2,a market subject game stage; S3, a market signal updating stage of the transaction center platform; S4, a distributed interactive iteration stage; and S5, a transaction clearing stage. According to the method, multilateral transaction and energy transmission between a plurality of virtual power plants and a plurality of load aggregators in a region are realized, the problem of energy coordinationand distribution between the virtual power plants and the load aggregators is solved, and fair, efficient, flexible and safe energy transaction of multi-party subjects is satisfied. By adopting the distributed algorithm, the energy supply cost of the virtual power plant in the multi-energy market is reduced, the power utilization benefit of the load aggregator on the demand side is improved, andthe information security of each benefit subject is guaranteed while the social welfare is maximized.

Description

technical field [0001] The invention relates to the field of virtual power plants participating in market transactions, in particular to a distributed transaction method for multiple virtual power plants and load aggregators. Background technique [0002] In the face of the increasingly depleted fossil energy, increasingly severe environmental pollution, and the growing hazards of the greenhouse effect, in order to increase the proportion of clean energy power generation in the grid, distributed power generation and virtual power plant technologies combined with new energy are getting more and more theoretical research and practical application. Distributed power sources give full play to the coordination and complementarity of distributed power demands and resources, and virtual power plants realize efficient and economical operation of the system by integrating distributed power sources and distributed energy storage. However, the coordination and scheduling between multi...
