Optical storage power station energy storage capacity optimization method based on dynamic electricity price and related device

Abstract

The invention discloses an optical storage power station energy storage capacity optimization method based on a dynamic electricity price and a related device. The method comprises the following steps: obtaining a dynamic adjustment electricity price lambda (t) and an evaluation condition value-at-risk CVaR alpha; on the basis of the dynamic adjustment electricity price lambda (t) and the evaluation condition value-at-risk CVaR alpha, an energy storage capacity optimal model is constructed with the goals of maximizing the total net benefit, minimizing the annual output deviation penalty cost and minimizing the annual self-electricity consumption electricity purchasing time period; the energy storage capacity optimal model is solved, the optimal energy storage capacity of the optical storage power station is obtained, energy storage capacity optimization of the optical storage power station based on the dynamic electricity price is completed, and the energy storage capacity optimization of the optical storage power station can be carried out by considering the multi-time scale electricity price response and the market risk.
