FIMERS CENTRALIZED STORAGE INVERTERS (ESS) are suitable for any type of storage applications like:
RENEWABLE ENERGY GENERATION
Capacity firming: power generation by a renewable source can be maintained at a defined level for a period of time having the ESS compensating the energy. Voltage and power swings on the network are smoothed as well.
Four quadrant operation: the ESS is able to generate or absorb both Active and Reactive power.
Peak shaving: the excess of the energy produced can be stored and be released when needed. Therefore grid or generators upgrades can be postponed and the price of energy can be maximised.
Fault Ride Through - FRT: the ESS can support the FRT according to the local requirements.
Frequency regulation: in case of Grid frequency increase or decrease, the Energy Storage System absorbs or releases Active power with an extremely rapid time response.
GRID ANCILLARY SERVICES
Frequency regulation: in case of Grid frequency increase or decrease, the Energy Storage System is charged or discharged with an extremely rapid time response.
Spinning reserve: the Energy Storage System is charged and ready to respond to a Grid (generation or transmission) outage. The time response is adjustable according to the network requirements. The operation of the generators can be optimised since idle capacity is no more necessary.
Voltage regulation: in case of Grid voltage increase or decrease, the Energy Storage System is charged or discharged with an extremely rapid time response.
Capacity firming: power generation by a renewable source can be maintained at a defined level for a period of time having the ESS compensating the energy. Voltage and power swings on the network are smoothed as well.
Load leveling: the excess of the energy produced can be stored and be released during high demand periods. Therefore grid or generators upgrades can be postponed and the price of energy can be maximised.
Peak shaving: in case of variable loads, the energy peak demand can be supplied by the ESS. Therefore network or generation investments can be avoided or postponed and the cost of energy can be minimised.
A typical application is in Railroad (Railway, Metro, Tramway and Trolleybus) where the accelerating or breaking of trains generate peaks (in demand or supply) that can be absorbed by the ESS.
Power quality: thanks to the fast response time, the ESS helps to protect the loads against short duration events (voltage dips, frequency variation, etc.) that affect the quality of the energy.
MINI GRID & ENERGY MANAGEMENT
On-line management of the power flows between the different sources
Contemporary load supply with all the sources: PV, Batteries, Diesel Genset and Grid
Load supply from the Grid through a by-pass or through the Power Converter.
