Virtual power plant optimization cooperative scheduling method based on electric vehicle V2G mode

Abstract

The invention discloses a virtual power plant optimization cooperative scheduling method based on an electric vehicle V2G mode. The method comprises the steps: building a detailed battery model considering the electric vehicle V2G mode, and taking the maximum operation cost of a virtual power plant subtracted from the expected revenue of a day-ahead market and a real-time market as a target; establishing a mixed integer linear programming model of virtual power plant optimal cooperative scheduling based on an electric vehicle V2G mode; on the premise of meeting virtual power plant constraintsand electric vehicle constraints, solving the mixed integer linear programming model, scheduling each energy source in the virtual power plant based on a solving result, scheduling a charging stationand participating in market bidding; aiming at a scene containing a large-scale distributed power supply and a large number of electric vehicles, a V2G mode of the electric vehicles is considered, anoptimal cooperative scheduling model depending on a virtual power plant is given, and theoretical guidance is provided for reducing market operation cost and improving behavior decision of distributedpower supply absorption 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.
