Control algorithms for power converters and stability analyses for grids
Description
IMDEA Energy has developed novel control algorithms for power converters to guarantee the stability of power system and flexibility needed for the integration of renewable sources and energy storage systems. The algorithms are verified using small signal modelling techniques, computer simulation and lab Power-HIL facilities.
Further deployment of renewable energy technologies and decarbonization of energy supply mix in electricity networks are both pending on a consensual solution for a series of complex legal, economic and technical issues. This fact underlines the importance of introducing novel flexible power network architectures and development of new network control algorithms for power converters serving as interface for renewable power sources and energy storage.
IMDEA Energy has developed new control algorithms for power converter in grid and microgrid applications:
- Grid-feeding and Grid-forming algorithms for renewable and storage applications in microgrids and distribution networks.
- Transient stability assessment and inertial services with renewable and storage converters. Voltage stability assessment and control for microgrids and distribution network.
- Analyses and control of hybrid AC, DC and mixed power networks.
- Aggregated control of distributed energy storage.
- Algorithms for HVDC links and Power Oscillation Damping
- Real-time algorithms for testing electrical energy conversion and power interfaces. Power electronics converters emulating operation and dynamics of real AC and DC power networks.
- Control algorithm testing and validation in PHIL environment.
- Simple code generation and code transfer to any control platform.
