Dynamic security of the Cyprus low-inertia transmission system
Background
The high penetration of RES in Modern Smart Grids leads to the decommissioning of synchronous generators that traditionally provided the necessary support to ensure the security and stability of power systems. Thus, the resulting power systems exhibit a wide range of security and stability problems, labeled as “low-inertia” problems 1. It is imperative to analyze these problems, using dynamic system models and future energy scenarios, and to develop solutions that will mitigate the impact.
Objectives
In this project, you have to translate the dynamic model of the Cyprus into the dynamic simulator PyRAMSES2. Following, an analysis will be performed using different future energy scenarios and solutions will be provided to enhance the stability of the Cyprus system.
Deliverables
- A complete literature review on the problems of future low-inertia grids, like the Cyprus system1.
- A Python-based translator from DigSilent PowerFactory format to PyRAMSES2. This translator will be used to generate the Cyprus dynamic system in PyRAMSES format.
- An analysis of the system behaviour (transient behaviour to disturbances, load variation, etc.)
- Proposed solutions based on storage or artificial inertia.
Student profile
- Good analytical skills.
- Good programming skills (Python or willingness to learn fast).
- Background in electric power systems (minimum Power Systems I).
