Abstract

The invention discloses a method for controlling participation of electric bus batteries in V2G in consideration of interests of multiple parties. The method comprises the following steps of acquiringa day-ahead electricity price, load data and a bus operation schedule; establishing a progressive bus management mode; computing available V2G charge / discharge capacity of an electric bus battery cluster at any moment; establishing an electric bus company operation cost minimization model and a power grid load peak valley difference minimization model; establishing a multi-objective optimizationmodel of the electric bus battery cluster; and solving to obtain a charge / discharge plan of the electric bus battery cluster under the day-ahead time scale. According to the method, the available V2Gcharge / discharge capacity of the electric bus battery cluster at any moment is computed on the basis of a "progressive" electric bus management mode, and is used as a constraint condition of the electric bus company operation cost minimization model and the power grid load peak valley difference minimization model, and meanwhile, a multi-objective optimization method is adopted, so that an optimalcontrol strategy for participation of the electric bus battery cluster in the V2G is obtained.

Description

technical field [0001] The invention belongs to the technical field of vehicle-to-grid (V2G) interaction, and relates to a V2G control method for an electric bus battery that takes into account the interests of multiple parties, in particular to an electric bus that takes into account the interests of both the electric bus company and the power grid. The vehicle battery cluster participates in the V2G control method. Background technique [0002] With the increasing penetration of electric vehicles in the grid, the charging / discharging behavior of electric vehicles has brought new challenges to the operation of the grid. Due to the random charging / discharging behavior of a large number of electric vehicles and the huge charging load, the safe operation of the grid will be significantly affected, and thus cause various potential problems, such as power quality degradation, voltage fluctuations, and overload. In order to solve the negative impact of electric vehicle charging / ...
