About the project
Objective
- Develop an accurate and computationally efficient model of power-electronics-dominated microgrids with distributed renewable energy sources.
- Establish electrical-parameter-dependent Lyapunov methods for analysing microgrid stability and robustness under time-varying loads and network conditions.
- Design distributed event-triggered control strategies that enable reliable, communication-efficient, and scalable operation of renewable-energy microgrids.
Background
The transition towards renewable energy is increasing the complexity of modern power systems. Microgrids with high shares of distributed renewable energy sources rely on power-electronic converters, communication networks, and coordinated control, making their modelling, stability analysis, and operation challenging.
This project will develop event-triggered networked control methods for microgrids, combining control theory, power systems, network science, and data-driven methods. The goal is to improve the reliability, resilience, and efficiency of future renewable-energy systems while reducing unnecessary communication and supporting the sustainable digital transformation of energy infrastructure.
