FOR ISOLATED HYBRID SYSTEMS
Energy Management System (EMS)
E22 has developed an EMS for isolated hybrid systems. These hybrid generation systems use a diesel generator as a backup system to a renewable generation system, usually wind, photovoltaic or mixed.
The energy management system minimizes the fuel consumption of the diesel generator by making optimal use of the energy provided by the renewable generation system.
A battery-based storage system makes it possible to optimise the system without penalising the cost of the installation.
Our system is scalable through parallel operation of the necessary number of storage units.
DYNAMIC REACTIVE COMPENSATION SYSTEM
Centralized control system
E22 has developed an innovative dynamic reactive compensation system of DSTATCOM type. A centralized control system that allows distributed control of the different units arranged in the generation park and also integrate passive compensation elements in order to minimize the cost of the solution, but without affecting the flexibility and speed of response of the overall solution. The system has several control modes: voltage control, voltage-reactive control, power factor regulation.
The solution for grid connection of PV solar plants
E22 has designed a solution for the grid connection of photovoltaic plants, based on a modular solution of IGBT electronic converters.
This solution allows the injection of the electrical energy from the PV plant to the grid complying with the most demanding grid requirements (Grid Codes).
POWER CONTROL SYSTEMS
B2GRID and GRIDMAKER
Our battery power control system solutions, capable of operating connected or isolated to the grid. Both are based on an inverter for modular batteries, being possible to use different battery technologies, such as flow batteries, lithium, lead, etc..
Provides different grid services. It’s applications are implemented on the platform, being able to be commanded from third party applications.
Control of microgrids and isolated grids that allow the integration of renewable energy sources in an efficient and reliable way.
Power electronics solution to maintain constant voltage and frequency in the microgrid, allowing the connection of any type of distributed resources.
Stabilizes the voltage and frequency of the grid maintaining the balance of active and reactive power in the microgrid.
In conditions of unbalanced demand, it is capable of balancing the supply, preventing the generators connected to the microgrid from being subjected to these disturbances.
It uses a direct voltage and frequency control system that provides optimum dynamic behaviour.
In addition to isolated operation, it can operate connected to strong or weak grids. An efficient island detection system allows a free transient adjustment between each operating mode.
Connected to the grid, it can operate in self-consumption mode, minimizing grid consumption and avoiding grid injection if the regulations penalize it.
