Abstract

The invention provides a control system of an energy storage power station, and a communication method of the control system. The control system comprises a central controller and a plurality of energy-storing containers. The energy-storing container comprises a first energy-storing container and a plurality of second energy-storing containers. The first energy-storing container comprises a mastercontroller and a slave controller, and each second energy-storing container comprises a slave controller. The central controller, the master controller and each slave controller respectively comprisean EtherCAT communication module, which enables the central controller and the master controller, and the master controller and each slave controller to communicate through the EtherCAT protocol. Theinvention is advantageous in that the response of the central controller can be improved; the synchronization among the energy-storing containers can be increased; the demand of power grid can be metat the same time, and the stability of power grid can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field, and in particular to a control system of an energy storage power station and a communication method for the control system. Background technique [0002] With the continuous improvement of the cost performance of energy storage, energy storage power stations, as an effective means of peak regulation and frequency regulation, have gradually attracted the attention of the power grid, and their capacity in the power grid has continued to increase. For mega-level energy storage power stations, energy storage containers have become the first choice for new energy storage power stations and building energy storage in the grid due to their small footprint and high cost performance. In order to meet the needs of the grid, the central controller of the energy storage power station needs to schedule multiple energy storage containers. In addition, the energy storage container needs to send ...
