In the energy storage system, the EMS communication topology is divided into two layers. The top layer is the general centralized monitoring system.
Bottom equipment: energy storage converter, battery management system (BMS), environmental monitoring equipment, fire protection system, air conditioning or access control system, etc. are all connected to the monitoring system (currently with administrator authority management, soft access control).
The monitoring host completes the network connection, conversion, data acquisition, data local processing, protocol conversion and command exchange between the on-site monitoring and control systems, local user screen monitoring operation, control strategy, and WEB server functions, and realizes the high-speed collection and transmission of large-capacity real-time data, so as to ensure that the master station system can quickly and accurately obtain all monitoring and monitoring information, and timely feed back the system abnormalities and faults detected by the network, Ensure fast positioning and recovery. (It needs to be realized through station-level BMS)

Application
Energy storage systems play a crucial role in modern energy management by storing excess energy during times of low demand and releasing it when demand is high. Here are various applications for energy storage systems:
Energy storage helps maintain the stability of the electrical grid by providing quick responses to fluctuations in power demand and supply, thereby stabilizing the grid frequency.
Storage systems can help regulate and stabilize voltage levels on the grid, ensuring a consistent and reliable power supply.
Energy storage helps address the intermittent nature of renewable energy sources, such as solar and wind, by storing excess energy when it's abundant and releasing it when generation is low.
Energy storage systems can store excess energy during periods of high renewable energy generation and release it during peak demand times, reducing the need for additional generation capacity.
Energy storage provides backup power to critical facilities, such as hospitals, data centers, and emergency services, ensuring continuity during power outages.
Large industrial facilities can use energy storage to manage and reduce peak demand charges, leading to cost savings.
