Power System Dynamics
Definition
This topic encompasses the dynamic behaviour of power systems and changes due to decarbonisation pathways, increasing penetration of converter-interfaced generation technologies, loads, and transmission devices.
The growing complexity and consequent challenges in system dynamics and stability have led to the need of understanding new phenomena and their interactions with existing phenomena and system components, as well as the design and implementation of practical innovative solutions. It requires the development of new components and their modelling, an extension of existing benchmark systems, and a communication layer integration with respect to having a testing environment with high fidelity, which allows extension of cyber-physical system testing, and testing of new control and detection techniques such as AI/ML-based methods.
Challenges
- Jeopardise the power system dynamics due to low-inertia conditions
- Power system splitting and possible mitigations
- Impact of Aggregated assets on the power system dynamics
- Resonance and Converter-driven stability phenomena and their impact/interaction with existing stability phenomena
- Operating conditions with faster electromechanical dynamics, where controllers and protection devices have shorter time frames to react
- Development of advanced solutions to effectively deal with emerging power system stability issues in real time (e.g., based on data-driven techniques)
- Efficient transmission of significantly high volumes of electric power from long-distance located renewable energy generation plants
- Increasing uncertainties and highly complex dynamics emerging from the massive deployment of converter-interfaced sources
- Development of advanced tools for enhanced situational awareness and more effective decision-making against critical operating conditions (e.g., based on the exploitation of PMU measurements through data analytics and ML algorithms)
