Abstract

With the popularity of electric vehicles, the charging load increases gradually. A large number of disorderly connected electric vehicles will have a great impact on the power grid. Electric vehicle is a kind of schedulable energy storage resource with the dual characteristics of power supply and load, which has the ability of active regulation. In view of the above problems, using multi-agent consensus algorithm, taking the incremental cost of generator sets and the incremental benefit of aggregate electric vehicle as consensus variables, a strategy for aggregate electric vehicles to participate in power system economic dispatch is designed, and the economic dispatch problem is solved by distributed optimization. An example simulation is carried out on the IEEE 39 bus system, and the aggregate electric vehicles are connected to the power grid step-by-step to verify the effectiveness of the proposed strategy.
