Optimal collaborative scheduling method of virtual power plant based on electric vehicle v2g mode

Abstract

The invention discloses a virtual power plant optimization and collaborative scheduling method based on the electric vehicle V2G mode, which establishes a detailed battery model considering the electric vehicle V2G mode, and aims to maximize the expected income of the day-ahead market and the real-time market minus the operating cost of the virtual power plant. Establish a mixed integer linear programming model for the optimal coordinated scheduling of virtual power plants based on the V2G model of electric vehicles; on the premise of satisfying the constraints of virtual power plants and electric vehicles, solve the mixed integer linear programming model, and based on the solution results, each Scheduling energy, scheduling charging stations and participating in market bidding; the present invention aims at scenarios containing large-scale distributed power sources and a large number of electric vehicles, considering the V2G mode of electric vehicles, and provides an optimal collaborative scheduling model relying on virtual power plants , to provide theoretical guidance for behavioral decision-making to reduce market operating costs and improve distributed power consumption capacity.

Description

technical field [0001] The invention relates to the technical field of electric power dispatching, in particular to a virtual power plant optimization and collaborative dispatching method based on the electric vehicle V2G mode. Background technique [0002] Due to its reliability, flexibility, economy, and environmental protection, distributed power is gradually widely used in power systems in various countries to deal with energy shortages, environmental protection and other issues. However, the volatility, randomness, and intermittency of distributed power generation bring risks to the security and stability of the power system; The idea of ​​distributed development goes against the grain. Therefore, the coordinated control and energy management of distributed power sources have become the focus of domestic and foreign academic and industrial circles. [0003] In 1997, Shimon Awerbuch first proposed the concept of a virtual power plant. As a cluster of aggregated distrib...

Problems solved by technology

In the traditional situation without charge and discharge regulation, a large number of uncontrolled electric vehicles will cause problems such as power flow and voltage fluctuations in the distribution network, overloading of transformers, and severe energy loss.
