SMART ESS

WHY ENERGY STORAGE
 
Fundamentally, countries worldwide are actively making steps towards creating more energy efficient and yet cleaner cities. As the energy industry moves away from carbon-heavy production, renewable energy and storage is being critical for delivering on the demand while securing the future of world energy and playing a prominent role in a grid that is migrating to a higher penetration of renewable energy, smarter grids, and flexible grids.
However, high penetration creates power transmission instability challenges, thus Grid Operators require stringent dynamic and static grid support features for Power Conversion Systems.

ENSMART HAS SOLUTIONS FOR THE CHALLENGE OF ENERGY STABILITY
 
Challenges that Smart ESS can address:

• Output variability,
• The temporal (time-related) mismatch between generation and demand,
• Uncertainty regarding weather forecasts, and
• Undesirable electrical effects on the electrical grid caused by some RE generation.


• Smart ESS solution offers proven hardware to meet storage and grid support challenges.
  
  Smart ESS system is fully compliant with grid systems to import and export power inline with the voltage and frequency regulations, FFR and DFFR schemes required by utilities to support the grid. Smart ESS can be used to support the stabilization of the grid to manage the consumption and the production of renewable energy.

COMPLETE ESS SOLUTION FROM SINGLE SOURCE
 
Smart ESS is a fully integrated turnkey energy storage solution that are ready for connection to medium-or high-voltage grids and cover a power range of hundreds of megawatts.

The containerised ESS system is available with 400kW, 500kW, 600kW, 1000kW capacities by using 20GP or 40HQ containers. Fully bunded ISO Container is designed with personnel and maintenance access doors and has air conditioned seperate converter and battery compartments.

Ensmart's self developed Battery Management System is a web-based integrated battery monitoring and management system, that monitors the temperature, internal resistance, and voltage of every single battery in a system.
The BMS calibrates the charging voltage of all batteries with the charger‘s target value, keeping all batteries within optimal voltage operating range. This guarantees the availability and capacity of every singly battery at 100%.
Ensmart BMS is the perfect system for all battery technologies: Sealed and closed wet cells, Gel and AGM, NiCd, NiMH, Li-Ion.
Benefits: Detect Imminent Battery Issues, Avoid Sulfation, Detect Stratification, Extension of Service Life by >30%, Protect Batteries
 

Individual Voltage Regulation:
 

The voltages of the 3 batteries behave differently given the regulating influence of the BMS modules. The ideal harmonic charging curve will be achieved for every battery in the string.

 

Avoid Undercharging:

The charging of Battery 3 is capped to prevent overcharging and gassing. Supply of charging energy to Battery 2 is continued and boosted until the target charging voltage is obtained. Battery 1 performs ideally and is not regulated.

The BMS Components

a. BMS Modules Measurement of voltage, temperature and internal resistance.
 
b. BMS Manager Monitoring of battery groups up to 240. Provides communication between BMS and UPS connection terminals environmental sensors.
 
c. BMS Measuring and Communication Cables Measurement and protection cables, data communication cable between modulels and module control unit.
 
d. External Temperature Sensor
 
Ensmart offers a future-oriented EMS/SCADA solution and for centralized and decentralized energy management to increase the availability of network, to collect energy data, to respond faster and more effectively to malfunctions, and to reduce the risk of system during disturbances and outages.

Thanks to Web-based SCADA system, GRM has real-time monitoring and remote control capabilities.
