The IN-AGS project is an R&D initiative focused on the design, implementation and validation of advanced network support functionalities integrated into our Master PPC (Master Power Plant Controller) centralised control system for hybrid renewable plants with storage. The aim of these functionalities is to contribute to improving the voltage and frequency stability of electrical power systems with high renewable energy penetration. The new functions will be implemented and validated in a real-time emulator (HIL) where the plant’s electrical and communications systems will be modelled.
Advanced control functionalities integrated into the MPPC
Power oscillation damping to improve the small signal stability of the system.
Inertia emulation to reinforce frequency stability and response to transient disturbances.
Adaptive voltage control to variations in the short-circuit power of the grid.
Coordinated control of active and reactive power PPC-converter during voltage dips.
Expected impact on the electricity system. What problems does it solve?
The proposed solution will enable the electricity grid to operate more stably and reliably in contexts with high renewable energy penetration. Through advanced controls, renewable plants will be able to actively contribute to system stability, reducing frequency and voltage problems that currently limit their integration.
The use of synthetic inertia techniques, supported by storage systems, will compensate for the loss of inertia associated with the reduction in conventional generation, improving the system’s response to disturbances. In addition, coordination between photovoltaic generation, batteries and the grid will facilitate more efficient integration, minimising oscillations, disturbances and operational risks.
Overall, the project will strengthen the reliability and resilience of the grid, reducing the likelihood of outages and improving its capacity to absorb large volumes of renewable generation. It will also enable smarter use of available resources, maximising their contribution to the electricity system without compromising the security or quality of supply.
Problems solved
Lack of inertia and short-circuit power due to the reduction in conventional generation.
Frequency and voltage stability problems, including inter-area oscillations.
Need for advanced coordination between multiple generators and resources, especially in hybrid plants.
Gap between current grid connection requirements and future regulation services demanded by operators, providing mature control solutions validated in real environments.
