Problems solved by technology
This method has the following disadvantages: In the scenario with a large number of storage and charging system units, first, the centralized control method has higher requirements on the transmission channel and central control equipment. Once the transmission channel or central control equipment fails, it will lead to distributed The overall collapse of the storage and charging system cluster; second, in order to improve the reliability of the central control equipment, multiple backup central control equipment can be set up, but this method will not only increase the cost of software and hardware, but also reduce the effective utilization of system equipment

The embodiment of the invention provides a distributed storage and charging system cluster and a control method thereof, the distributed storage and charging system cluster comprises a plurality of storage and charging system units, and the method comprises the following steps: determining one storage and charging system unit as a master node, and the other storage and charging system units as slave nodes; the main node generates a control instruction according to the operation information of each storage and charging system unit; and each storage and charging system unit operates according to the control instruction. The embodiment of the invention can achieve the following beneficial effects: firstly, a decentralized distributed storage and charging system cluster coordination control mode is adopted, and a fixed central control device does not need to be arranged; and 2, each storage and charging system unit publishes respective equipment parameters, running states and other contents in a message queue manner. And thirdly, the current unique main node storage and charging system unit is determined as the virtual host through a competitive election algorithm, so that stable operation of the cluster can be still ensured when the current virtual host is down.
Description
technical field [0001] The present application relates to the technical field of power transformation and distribution, in particular to a cluster of distributed storage and charging systems and a control method thereof. Background technique [0002] As an important part of the power system, the energy storage system plays an important role in various links such as power generation, power transmission, power distribution, and power consumption. Compared with the traditional large-scale centralized energy storage system, the distributed storage and charging system (DSCS, Decentralized Storage / Charge System) has the characteristics of flexibility, speed, convenience, etc., and has achieved rapid development on the user side in recent years. For example, with the development of the electric vehicle industry, the distributed storage and charging system is combined with DC fast charging and super charging piles. Because the storage and charging system has the characteristics of s...
