ADVANCED ANCILLARY SERVICES TO MEET THE MOST DEMANDING FACTS REQUIREMENTS
Electrical authorities demand control requirements that plants must meet to guarantee system stability. Key among these is the Limitation of Power (Power Curtailment), adjusting available production to real demand. Others, such as Ramp Rate Control, soften the impact of sudden changes in environmental conditions affecting renewable energy generation.
eks Energy flexible alternating current transmission systems (FACTS) provide reactive power control with the finest response to meet FACTS requirements at all times. Since 2006, eks Energy has installed these flexible alternating current transmission systems in energy plants with a total capacity exceeding 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 flexible AC transmission system 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
Flexible alternating current transmission systems (FACTS) play a pivotal role in advancing substation automation. By providing dynamic and precise control of electrical variables, FACTS enhance the efficiency and reliability of substations.
These flexible alternatig current transmission systems integrate seamlessly with energy management systems (EMS) and SCADA, enabling centralized and automated monitoring. FACTS respond rapidly to load changes and power flow fluctuations, reducing manual interventions and ensuring a stable power supply. Embrace the future of substations automation with flexible alternating current transmission systems for a smarter and more efficient grid.
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 a UPS. This functionality is based on the capacity of the eks Energy solutions to change its operation mode from the standard one as a 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. This showcases how flexible alternating current transmission systems can adapt to emergency conditions, ensuring continuous power supply and enhancing grid reliability.
