Electric car and cloud energy storage economic scheduling method based on dynamic non-cooperative game

Abstract

The invention puts forward an electric car and cloud energy storage economic scheduling method based on a dynamic non-cooperative game. The method comprises the following steps that: (1) establishingan electric car agent economic optimization scheduling model; (2) establishing a three-party non-cooperative game model; and (3) adopting particle swarm optimization to solve the above model, and determining a final Nash equilibrium point. By use of the method, the concept of V2G (Vehicle-to-grid) and a cloud storage retailer is imported for inhibiting the volatility influence of intermittent energy power generation, an electric car can be used as a load and also can be used as an energy storage characteristic, and electric energy grid-generation commercial operation is realized on a premise that the own requirement of the EV car owner is met, and therefore, the maximum car owner benefits are pursed; and meanwhile, since a cloud energy storage retailer and the EV car owner agent has economic conflicts, on the basis of a non-cooperative game theory, solving is carried out so as to achieve the maximum car owner benefits. Compared with subjectivity that a solution set obtained by a traditional multi-objective optimization algorithm is decided and selected by an administrator, the method disclosed by the invention imports a game theory to improve the flexibility and the intelligence ofelectric energy utilization.

Description

technical field [0001] The invention discloses a dynamic non-cooperative game-based economic scheduling method for electric vehicles and cloud energy storage, and belongs to the technical field of power system automation. Background technique [0002] With the shortage of natural resources and the increasing environmental pollution, smart grid technology has received extensive attention from the power industry in various countries. As a mobile load, energy saving and environmental protection, electric vehicles are bound to become the development trend of the future automotive industry. However, since participating in electric energy dispatching has irreversible damage to the life of EV batteries, the government needs to provide certain support to encourage EV owners to actively participate in dispatching and play an important role in load transfer and load regulation. If the peak-valley electricity price is only used for peak shaving and valley filling, the impact on the di...
