EMS (Energy Management System): The Central Nervous System of Distributed Energy Storage Systems

In recent years, with the rapid development of renewable energy and advancements in energy storage technology, distributed energy systems have become more widely integrated into societal production and everyday life. However, renewable energy sources such as wind and solar power are heavily influenced by weather and their inherent physical characteristics, making them intermittent and variable, leading to unstable power generation. As a result, balancing and improving the efficiency of distributed energy has become critical, highlighting the importance of Energy Management Systems (EMS) in energy storage. EMS functions as the “central nervous system” of the energy storage system，just as the human central nervous system transmits chemical and electrical signals to coordinate various organs, EMS sends control instructions to manage devices and system operation. To begin with, EMS, as the core technology of an energy storage system, primarily provides the following functions: Data Collection and Monitoring Comprehensive Data Collection：EMS collects real-time operating data from various equipment within the energy storage system, including battery voltage, current, temperature and State of Charge (SOC), along with information from Power Conversion Systems (PCS), meters, air conditioning, fire fighting system， and various sensors. This ensures a full understanding of the system's real-time operating conditions. Centralized Monitoring and Display：EMS processes and visualizes key information such as charge/discharge levels, real-time power, battery status, and economic performance, providing users with an intuitive interface for system monitoring and enabling them to view overall operational conditions anytime. Energy Management and Optimization Charge/Discharge Strategy Development: EMS automatically adjusts the output of distributed power sources based on real-time energy prices, grid load, and user demand to establish a reasonable battery charge/discharge strategy. Operational Efficiency Optimization: By collecting and analyzing performance data, EMS identifies bottlenecks and inefficiencies in the energy system, allowing for operational improvements, parameter adjustments or layout modifications to enhance efficiency and reduce operational costs. Forecasting and Decision Support: Using advanced algorithms and big data technology, EMS forecasts future energy demand based on historical data, helping decision-makers develop more efficient, low-cost energy management strategies that yield high returns. Fault Diagnosis and Management EMS monitors battery and system anomalies in real time, issuing alerts and taking protective measures, such as isolating faulty equipment or activating backup systems to prevent issue escalation and ensure safe system operation. Fault diagnosis and analysis also aid in maintenance and repair planning. Economic Benefit Analysis and Evaluation EMS calculates the system's operational costs and benefits in real time, including electricity expenses, equipment investment, maintenance costs and revenue from peak-load shifting, demand response, etc. This helps users clearly understand the system's economic performance and supports their decision-making. Ancillary Services EMS exchanges information with the grid, responding to grid dispatch commands and participating in ancillary services like peak and frequency regulation and demand response, thus supporting grid stability. EMS adjusts the operation and power output of industrial and commercial energy storage systems based on grid conditions, ensuring seamless integration. On the premise of meeting the above functions, When evaluating different EMS products, users should consider the following criteria: Stable Operation, Safe and Reliable Performance The system should include power quality monitoring, anti-islanding, anti-reverse flow protection, control and monitoring devices, and other components to ensure safe, stable operation. Fast Installation , Multiple Integration As the“central nervous system”of the system, EMS must interface with multiple devices, including BMS, PCS, meters, air conditioning, fire fighting system, circuit breakers, indicators, and various sensors. It should support various protocols, enabling full data access from all control devices, especially the real-time integration of alarm signals, which requires high EMS data collection performance. Flexible Expansion，Intelligent Strategy Given the dispersed nature of distributed energy storage systems, currently, energy storage devices mostly use standard storage cabinets, like modular building blocks. To meet different energy demands, a varying number of storage cabinets are needed for expansion. EMS must have a flexible expansion capability to accommodate varying numbers of storage cabinets according to energy demands. Additionally, EMS should enable multi-dimensional data analysis and intell

On October 16th, the 2.4MW/5.16MWh BESS project undertaken by Vilion for an industrial park in Huizhou successfully completed all on-site acceptance tests (SAT) and commissioning work, passing all inspections. The industrial park is large, with numerous buildings, uneven power load distribution, and high energy consumption. Vilion designed a solution based on the client's energy needs, using its self-developed EnerArk battery energy storage system. The installed capacity is 2.4MW/5.16MWh, consisting of 24 units of 100kW/215kWh EnerArk integrated outdoor battery energy storage cabinets, 4 PowerHub combiner cabinets, 4 ViStarter Energy Management Systems (EMS), and anti-backflow devices. The system is connected to the transformer's 400V AC bus to achieve grid connection. Through the EMS, the system manages the switching of on-grid charging transformer and the energy storage system scheduling to optimize charging and discharging strategies. After the system is put into operation, the daily charging capacity is 10,492kWh, and the daily discharging capacity is 9,232kWh, with two charge-discharge cycles per day. Based on this, it is estimated that the daily electricity cost savings amount to approximately 5,655 CNY, and annual savings could reach over 2 million CNY. EnerArk is a compact plug-and-play battery energy storage system with an All-in-One design, integrating PCS, batteries, BMS, EMS, MPPT, an automatic fire protection system, and a temperature control system. It is easy to transport, install, and maintain. The system uses high-performance LFP batteries, with an intelligent BMS providing five layers of safety protection to ensure high security and reliability. Additionally, the system supports both AC and DC photovoltaic coupling and offers 24/7 online monitoring. Once the project is connected to the grid and fully operational, it will effectively alleviate the power load of enterprises in the park, reduce their electricity costs, and help them increase efficiency and reduce costs.
