Dyness Knowledge | The role of EMS in small and medium-sized C&I energy storage systems

With the rapid development and application of renewable energy, small and medium-sized industrial and commercial energy storage systems are playing an increasingly important role in improving energy efficiency, reducing energy costs, and enhancing energy security. In this process, the energy management system (EMS) is one of the core components, and its function and value cannot be ignored. This article will explore the role of EMS in small and medium-sized industrial and commercial energy storage systems.

Optimize energy management

First, EMS can monitor and control various devices in the energy storage system in real time, including batteries, inverters, load devices, etc. This real-time monitoring can not only provide feedback on the system's operating status, but also intelligently dispatch the charging and discharging strategies of the energy storage system according to changes in electricity demand and electricity prices. For example, during periods of low electricity prices, EMS can command the system to actively charge, while during peak electricity prices, it can choose to discharge. This intelligent dispatching effectively reduces energy costs and improves economic benefits.

Increase the utilization rate of renewable energy

Small and medium-sized businesses often connect to the grid with renewable energy sources such as solar energy and wind energy. EMS can maximize the use of renewable energy by predicting the power generation of renewable energy and formulating reasonable energy management strategies based on load demand. For example, by analyzing weather forecasts and historical data, EMS can predict the peak and trough of solar power generation, and adjust the charging and discharging of energy storage devices based on this information, thereby reducing dependence on traditional energy and promoting the use of green energy.

Enhance grid interaction

The EMS of small and medium-sized industrial and commercial energy storage systems can interact with the power grid in a two-way manner. When the power grid load is peaking, the energy storage system can feed back the stored electric energy to the power grid to help balance power supply and demand. At the same time, the EMS can also flexibly adjust its own discharge strategy according to the demand signal of the power grid and participate in the auxiliary services such as frequency regulation and peak regulation of the power grid. This interaction not only improves the stability of the power grid, but also brings additional economic benefits to the energy storage system.

Ensure power stability

The energy storage system plays the role of a "regulator" in the power supply, and the intelligent control of EMS can effectively improve the stability of the power system. When the power load changes sharply, the biomass power generation fluctuates or a failure occurs, EMS can quickly take measures to adjust the working state of the energy storage unit to provide the necessary power support and ensure the normal operation of the enterprise. This is especially important for some small and medium-sized industries and businesses that have high requirements for power reliability.

Realize intelligence and remote management

With the development of the Internet of Things and big data technology, the intelligence level of EMS continues to improve. Modern EMS can not only realize local control of energy storage systems, but also support remote monitoring and management through cloud technology. Users can check system status, historical data analysis, fault alarm and other functions at any time through mobile phones or computer platforms. The convenience of this remote management greatly reduces the dependence on human resources and improves management efficiency.

In summary, the energy management system (EMS) plays a vital role in the energy storage system of small and medium-sized industrial and commercial enterprises. Through intelligent scheduling optimization, enhanced utilization of renewable energy, multi-interactive power grid, voltage-stabilized power supply, remote intelligent management and support for sustainable development, EMS not only improves the economic benefits of the system, but also provides strong support for the green transformation of enterprises. In the future, with the continuous advancement of technology, EMS will play a greater role in the energy management of small and medium-sized industrial and commercial enterprises, helping enterprises to achieve more efficient and environmentally friendly energy use.
