Optimization strategy of virtual power plant participating in power spot market

In order to solve the problem of the influence of large-scale distributed energy on power grid and the invisibility of small-capacity distributed energy on power grid dispatching, virtual power plant is used to solve such problems. This paper uses robust optimization method to deal with the uncertainty of spot price, establishes the objective function, establishes a robust equivalence model through the existing constraints, and verifies the effectiveness of the model through simulation examples.
