ADVANCED ANCILLARY SERVICES TO MEET THE MOST DEMANDING FACTS REQUIREMENTS
Electrical authorities demand for control requirements that plants must meet to guarantee system stability. Some of them, with special relevance, such as the Limitation of Power (Power Curtailment) which adjusts available production to real demand. Others, as the Ramp Rate Control, allows softens the impact caused by sudden changes in environmental conditions that may affect the instantaneous capacity to generate renewable energy.
eks Energy FACTS solutions provide a source of reactive power control with the finest response to meet the FACTS requirements all time. Since 2006, eks Energy has installed in energy plants with a total capacity which currently exceeds 1GW.
GRID CODE REQUIREMENTS COMPLIANCE
Voltage control is performed by the reactive capacity of installed systems. These are managed by the Power Plant Controller based on the FACTS operator references.
eks Energy technology offers added values of signal quality through its advanced function for generation and control of Reactive Power. Our FACTS Stability solutions together with eks Energy conversion systems solve reactive and active power challenges.
OPTIMAL
INTEGRATION AND FAST RESPONSE
The development of own monitoring tools, together with the possibility of integration with third party SCADA solutions ensure a rapid and flexible solution.
In order to achieve optimum integration, we select the most widely accepted protocols adjusting the final features for each project.

ISLANDING OPERATION
Related to FACTS Capabilities needs, eks Energy technologies offer different operation options in case of Islanding conditions, either they are expected or not.
Black-Start
Plant controls remain online during an outage but the plant ceases backup. While the plant can restart operations shortly, a few seconds (even less than a second), after the substation is configured, the exact timing will depend on coordination with grid operator.
Duration & Endurance
Once islanded, the connected loads (previously defined) will draw all power from the power plant.
Island Power Quality
All power quality requirements specified in the interconnection agreement will be applied to islanded performance pending approval of the grid operator regarding critical load transients.
FACTS Resynchro
The Power plant will be expected to resynchronize with the FACTS when it returns to nominal conditions without disturbance to the different loads.
Auxiliary Voltage generator
The Auxiliary Services Transformer can be fed directly from the inverter output in case of a grid loss, allowing an emergency operation of the system during the day hours without the installation of an UPS.This functionality is based on the capacity of the eks Energy solutions to change its operation mode from the standard one as current source to the grid former operation mode. As the inverter is going to generate an independent grid, this operation mode involves the inverter being disconnected from the grid before it starts to feed any load
