Abstract

The invention discloses a control method of an energy storage system and a control device of the system. The method comprises the following steps: the operating state of a power grid is detected, and the power grid is a power grid attached with the energy storage system; a control manner is determined according to the operating state of the power grid, wherein the control manner is used for controlling the energy storage system; according to the control manner, the energy storage system is controlled to operate the power grid. The method and the device can solve the problem that the power grid has unsteady operation in an existing technology when the power grid is overloaded due to existence of multiple direct current charging stations.

Description

technical field [0001] The invention relates to the field of electric energy, in particular to a control method and device for an energy storage system. Background technique [0002] With the increasingly prominent problems of energy shortage and environmental pollution, electric vehicles have attracted widespread attention due to their advantages of energy saving and environmental protection, and have formed a new round of upsurge in the development of new energy vehicles on a global scale. Automobile is listed as one of the country's seven strategic emerging industries. According to the "Energy Saving and New Energy Automobile Industry Development Plan" issued in 2012, it is estimated that the cumulative production and sales of pure electric vehicles and plug-in hybrid electric vehicles will reach 500,000 in 2015, and when the capacity of the power battery for the vehicle drops to its rated capacity When 80% of the battery is used, a large number of power batteries will b...
