Abstract

The invention relates to an energy storage cluster control system and an energy storage system. The energy storage cluster control system is used for frequency modulation of a power grid generating set. In the energy storage cluster control system, an energy storage cluster controller is used for receiving an adjusting power value and a frequency modulation control command and the current volume and state of an energy storage unit, receiving the information of an energy storage current transformer and a cell management system in real time, and sending a first command to an energy storage unit controller; the energy storage unit controller is used for receiving the first command and the information sent from the energy storage current transformer and the cell management system to make a judgment to generate a first control signal, and sending the first control signal to the energy storage current transformer to perform charge-discharge control; and the energy storage current transformer is used for receiving the first control signal, and timely sending the information of internal and external equipment to the energy storage unit controller. By means of the technical scheme, the energy storage cluster control system and the energy storage system can solve the technical problem of how to satisfy quick timeliness and synchronism of the frequency modulation control demand of a platform configuration with a plurality of energy storage unit in parallel and a generating set.

Description

technical field [0001] The invention relates to the technical field of power system frequency regulation, in particular to an energy storage cluster control system and an energy storage system. Background technique [0002] At present, based on the rapid development of the power grid, the requirements for power system frequency modulation units are gradually increasing. The battery energy storage system has the ability of fast two-way power regulation, which can meet the needs of high-frequency short-term fast two-way power regulation. Therefore, the use of energy storage systems to assist generator set frequency regulation has become A new technology development and application trend. [0003] Based on the technical characteristics and safety considerations of the battery energy storage system, it is not suitable to use a single large-scale battery in parallel to form a large-capacity energy storage system solution; and the generator set has a large power demand for the ene...
