Starting from the experience gained in the field of
production systems from renewable sources connected
to the grid, Green ITEC provides solutions for the management of the grid
connected or off grid storage systems.
In the Industrial and Commercial scale in which
Green ITEC operates, essentially two types of storage
systems are provided:
- connected in parallel to a renewable source
production plant (photovoltaic, wind, etc) on the a.c.
side of the PCS; it is defined storage in a.c .. The PCS
manages the charging and discharging of the battery
and can be connected to the grid or to a micro-grid - connected in parallel to a renewable source
production plant (photovoltaic, wind) on the d.c. side of
the PCS; it is defined storage in d.c.. The PCS manages
the charge and discharge of a battery and the
renewable source plant and usually it is connected to a
micro-grid or it supplies off-grid loads
In any case, CLEANISLAND is able to operate both in “grid
following” and “grid forming” mode, switching from one to
the other without voltage drop.
CLEANISLAND can manage different types of batteries:
Lithium Batteries, Redox Flow Batteries, Salt Batteries.
CLEANISLAND is a DSP (Digital Signal Processor) based
converter system, specifically designed for energy
storage application and basically present two working
modes:
a) Grid Following – in this working mode the PCS is used
as a grid tied inverter to connect the energy Storage
system to the grid or micro-grid with the capability of
charging the batteries and/or to support the grid in
feeding the loads.
b) Grid Forming – in this working mode the PCS become
the master grid generator; it feeds the micro-grid
(allowing the operation also to the connected renewable
energy system) or local loads taking energy from the
batteries
