When the microgrid’s energy generation exceeds all the loads on it, the microgrid can charge its energy storage devices, such as batteries, via a bidirectional AC/DC converter. The use loads (both AC and DC) are connected to a common AC bus (backbone network). Microgrids can also send out (export) energy to the utility power grid.
A Microgrid controller such as the ePowerControl MC (Microgrid Controller) controls and monitors the charging and discharging of the Battery Energy Storage Systems. It prevents the system from overcharging and also protects against deep discharging. Microgrid controllers specify a predefined maximum voltage and a final discharge voltage.
In such off-grid power systems, battery management is best done through the use of a microgrid controller and an energy monitoring platform. Elum Energy provides a wide range of solar products and ePowerControl MC and ePowerControl PPC along with our monitoring platform ePowerMonitor are best suited to perform these tasks effectively.
Not only that, but it is also critical for the maximum battery endurance, otherwise, the batteries will have to be replaced at a comparatively early stage. In the case of microgrids, it is also imperative that only one energy source can be grid forming. This means that this component sets the voltage and frequency of the whole grid.
The main difficulty around battery grid forming is that the state of charge of batteries is always a challenge to measure accurately. The ability to ascertain and accurately measure the charging level of your battery is a basic requirement for the correct operation of the whole system.
The first and foremost benefit of off-grid systems with battery grid forming is the fact that the site can rely on 100% renewable energy thanks to the diesel off mode. This induces a reduction of fuel consumption because the diesel generator is off but also a reduction of noise because the battery is the main grid-forming unit.
