A power plant controller that meets Fingrid’s requirements

GC-PPC is an industrial-grade control system for battery storage and for solar, wind and hybrid power plants. It meets Fingrid’s SJV2024 and VJV2024 requirements and can be integrated with equipment from any manufacturer.

Asmall plants
Active power control, over-frequency response (LFSM-O) and remote control by the network operator
B
+ active power limitation
C
+ voltage, reactive power and power factor control, LFSM-U, frequency sensitive mode (FSM), fast power reduction and a PSS/E model
Dtransmission grid
+ PSCAD model, with power system stabiliser (PSS) and power oscillation damping (POD) as options

GC-PPC covers Fingrid’s power plant types A–D. Each level includes the functions of the levels below it.

ExpertStrong expertise where electrical engineering, automation and renewable energy meet – you don’t have to teach your supplier.
FlexibleSolutions tailored to the size and requirements of your project, from type B to type D.
FastAs a Finnish company, we typically deliver a type B controller in weeks, not months.
HIL-testedEvery power plant controller is tested on a real-time simulator, covering the whole system, before delivery.

Controlled, stable and predictable operation in every situation

The Greencontrol power plant controller is an industrial-grade control system for renewable generation, storage and hybrid plants.

The same platform scales from small plants to type D plants connected to the transmission grid and to load control, and it can be integrated with equipment from any manufacturer.

Meets Fingrid’s requirements
SJV2024 and VJV2024 for different plant and connection types.
One platform, many applications
For wind, solar, battery and hybrid plants, and for load control.
Scalable
The same core system from small sites to system-critical power plants.
Reliable over the whole life cycle
Hardware and software designed for industrial use.
Ready to expand
Prepared for changes in grid requirements and project extensions.

For hybrid plants the versions are GC-HPPC-A … GC-HPPC-D, with the same functions as the single-plant versions.

Every controller is tested before delivery

The power plant controller is verified in the lab for the whole system, so issues are found before site work rather than during commissioning.

HIL testing with a real-time simulator
We run hardware-in-the-loop (HIL) tests for every power plant controller, covering the whole system. The controller is connected to a real-time simulator and tested before delivery.
Project-specific PSCAD model
The PSCAD simulation model of the controller is made in line with Fingrid’s latest modelling guideline, compatible with CIGRE/IEEE B4.82, and is based on the actual controller code.
PSS/E model
A PSS/E model of the controller is included in the type C and D versions.
