Connection form of collection system of battery energy storage power station The energy storage system is mainly composed of energy storage battery pack, power conversion system (PCS), battery management system (BMS), battery monitoring system (MNS) and other subsystems .
In addition to being affected by the external operating environment of storage system, the reliability of its internal electrical collection system also plays a decisive role in the safe operation of energy storage power station.
Due to its superior flexibility and regulation capacity, the battery energy storage system is currently planned and invested in large-scale construction, such as Dalian 200 MW/800 MWh liquid flow battery energy storage power station , Jiangsu Province has built user-side energy storage stations with a total capacity of 125 MW/787 MWh .
The battery energy storage power station is composed of battery clusters, PCS, lines, bus bar, transformer, and other power equipment. When the scale is large, the simulation method can be used to evaluate. When the scale is relatively small, the enumeration method can be used for reliability evaluation.
The battery energy storage system is a flexible resource with dual characteristics of source and load. It can be widely used in renewable energy consumption, peak shaving and frequency modulation, virtual power plant, and so on.
As shown in Fig. 1, the scale of energy storage battery pack from small to large is single battery (cell), battery module, battery cluster, battery system, etc., while the energy storage battery pack is composed of single batteries in series and parallel and connected to the power grid through the power conversion system.
