eksenergy.com

eks is born, inside the Greenpower
Technologies Group, as the result of a long
and thorough strategic analysis, to create
a new, autonomous and independent
company, focused on the storage
business.

eks has been working in the storage
sector since 2010. Despite being a new
company, eks enjoys a unique starting
point derived from its proprietary IP, the
experience of their team, who has been
working together for over the last years,
the solid track record of the group in the
sector and the trust of their clients.

eks solutions give a dynamic response to
the power demand from the utility,
complying with all the new requirements
the Grid Codes are requesting in the
different countries and making them
flexible to adapt to new requirements that
might come in the future

Our
commitments

The utility-scale energy storage market has
grown increasingly competitive since 2016 as
projects become economically viable for a
range of new applications in new geographies:
• The trend for modernizing grids to reach the

needed resilience level to accommodate
renewable power plants.
• The resulting need for smart grid and
ancillary services.
• Utilities and IPPs need to successfully built
secure and profitable ESS.

eks designs and optimizes the Energy Storage
Systems, leveraging their robust software,
control platforms, power electronics and field
experience to maximize the value of a project
for its clients.

Modbus TCP, Modbus RTU, DNP3 Serial, NTP, IEC 61850 (other protocols are possible)
Note1: The PPC can work simultaneously with different protocols, as different

communication protocols can exist in the PV plant.

Number of sub-networks: Configurable

Standard1: Only one network for control and monitoring

Communication networks Standard2: One sub-network for control and one sub-network for monitoring. This standard
is successful for very fast requirements.

Grid Stability and Control for Large-Scale Plants

PPC FEATURES

Controls at the Point of Interconnection

General Flexible and configurable Power plant controller with very high performance

Up to 50mS (configurable)

Standard1: 1000mS (slow applications)

Standard2: 100mS (fast applications)

Control time step Different options are possible, as this time is configurable.

Note1: The time step depends on the requirements of the grid code and the characteristics of the
equipment selected (inverters, grid analyzer…)

Note2: The PPC can work faster than 50mS, but this time is usually limited by other systems as

Power analyzers or the communication speed of the power converters

Active Power Control Power curtailment
Power ramp rate constraint

Frequency Stability Active power injection/absorption due to frequency variations (over-frequency and under-
frequency)

Voltage Control Voltage reference closed-loop control

Reactive power Control Reactive power closed-loop control

Power factor control Power factor closed-loop control

Clipping reduction and The PPC can store the clipping losses in the BESS and then export this stored energy when

Energy shifting required/scheduled

The PPC manage the power flow (active and reactive) in the facility when different generation

Energy management technologies are installed (BESS, PV sources, Capacitor banks…), so the PPC is able to manage
the energy at POI and at different points in the facility to meet the most demanding grid codes

and optimize the power generation.

Error/Alarm Handling Monitoring and notification of error and alarms

Grid Code Auto Check In order to verify the Grid Code Compliance, the PPC implements automatic validation profiles

functionality that can be carried out during the Site Acceptance Test.

Service/Maintenance System
