The EESS is composed of battery, converter and control system. In order to meet the demand for large capacity, energy storage power stations use a large number of single batteries in series or in parallel, which makes it easy to cause thermal runaway of batteries, which poses a serious threat to the safety of energy storage power stations.
Such as the thermal-electrical-chemical abuses led to safety accidents is increasing, which is a serious challenge for large-scale commercial application of electrochemical energy storage power stations (EESS).
A Station Level Solution inter-connects and integrates the bay level intelligent electronic devices (bay control and protection devices) using the well-proven IEC 61850 standard. It offers a central database, HMI & gateway functionality at the substation level. They are easy to use and to adapt to customer-specific requirements.
Through the incorporation of various aforementioned perspectives, the proposed system can be appropriately adapted to new power systems for a myriad of new energy sources in the future. Table 2. Comparative analysis of energy storage power stations with different structural types. storage mechanism; ensures privacy protection.
The energy storage system is a system that uses the arrangement of batteries and other electrical equipment to store electric energy (as shown in Fig. 6 b) . Most of the reported accidents of the energy storage power station are caused by the failure of the energy storage system.
By equipping the renewable power generation system with a large-scale fixed electrochemical energy storage station (EESS), it has a significant impact on the stability of the power grid and the optimal utilization of renewable energy power .
