Energy Storage Station EMS Energy Management System Solution

EMS Energy Management System

The battery energy storage system of the energy storage power station is used for peak shaving and valley filling for general grid distribution users. It stores the energy during off-peak electricity prices in the form of direct current in the battery matrix (battery stack). During peak electricity price periods, it outputs the energy to various electrical appliances and loads in the form of 50Hz alternating current, effectively using low-price energy during high-price periods. This peak-valley price difference brings significant energy storage and cost-saving benefits to users, leading to widespread adoption(sources from


System Overview

The Energy Management System (EMS) is a comprehensive energy management system introduced for lithium battery energy storage power stations. It achieves real-time monitoring, diagnostic warnings, panoramic analysis, and advanced control functions. It meets the demands for comprehensive operational monitoring, intelligent safety analysis, and dynamic panoramic analysis, ensuring the safe, reliable, and stable operation of energy storage power stations.

The EMS energy management system is suitable for system monitoring, power control, and energy management of projects such as energy storage stations, microgrids, and integrated new energy storage. It centrally monitors the Battery Management System (BMS) and Power Conversion System (PCS) of energy storage power stations, enabling unified operation, maintenance, inspection, and management. It facilitates rapid fault elimination, relieves grid pressure during peak loads, reduces grid operating costs, and enhances economic benefits.

Displaying recent historical data: peak-shaving electricity quantity for today and yesterday, this month, this week, yesterday, and 24-hour charging/discharging active power curves.


Monitoring and Control

Displaying the current charging/discharging status of the energy storage station and relevant key data.

Summarizing faults of multiple energy storage units in the energy storage power station, detailed information can be viewed by clicking on the corresponding indicators.

Displaying data for planned control of the energy storage power station, including real-time charging/discharging curves, daily planning curves, and intraday ultra-short-term curves.


Day-Ahead Planning

Charging/discharging plan maintenance: This page displays the charging/discharging plan, new energy forecast information curve, and energy storage charging/discharging information curve. Users can add, modify, or delete the charging/discharging plan for the energy storage station in the “Charging/Discharging Plan Maintenance” section. Different modes such as single charging/single discharging, double charging/double discharging, or single charging/double discharging can be used for peak shaving and valley filling, new energy absorption, simultaneous peak shaving and new energy absorption, and emergency power protection control strategies(quotes from medcom..

Historical plan inquiry: Selecting dates to query the corresponding time period’s scheduling plan values or system-generated energy storage charging/discharging plan values.


Alarm Inquiry

Users can query and export historical alarm information through the alarm interface, making it easy and accurate to find historical alarm information without the need to search through the system each time.
