Energy storage monitoring system

Abstract

The invention discloses an energy storage monitoring system. The system comprises an energy storage system and an energy management system EMS, the energy storage system comprises an energy storage battery, a battery management system BMS, an energy storage converter PCS and a transformer, wherein the transformer is connected to an alternating current bus in a power grid or a microgrid system, theenergy management system EMS comprises a server, a human-computer interface HMI, a telecontrol device and a coordination controller PMS, and the telecontrol device is connected with a dispatching center. The invention relates to an energy storage monitoring system. A monitoring system is combined with an energy storage system; on one hand, a power grid or micro-grid system scheduling instructionis received, on the other hand, the power grid or micro-grid system scheduling instruction is distributed to each energy storage branch according to an energy management strategy, the operation stateof the whole energy storage system is monitored at the same time, and randomness, intermittency and instability of power generation of a power system are effectively compensated and restrained.

Description

technical field [0001] The invention belongs to the field of electric energy storage, in particular to an energy storage monitoring system. Background technique [0002] The power production process is continuous, and the power generation-transmission-transformation-distribution-power consumption must be kept in balance at all times. Production and consumption are required to be completed at the same time. Instantaneous imbalances may lead to security and stability problems. However, in the power grid or micro-grid system, there are large differences in the power demand of users between day and night and different seasons, which makes the power system must have a large reserve capacity, and the operating efficiency of system equipment is low. In addition, due to the randomness, intermittentness and instability of power system power generation, assisting the power grid or micro-grid system in peak regulation, smoothing the output of electric energy, and improving the stabilit...
