Stability analysis of large power systems with 100% of non-synchronous generation

Future electrical energy systems all over the world are being planned to incorporate large amounts of renewable resources. Renewable resources such as wind turbines or photovoltaic (PV) solar panels are totally or partially coupled by voltage source converters (VSCs) (i.e. non-synchronous generation). Future power systems are tending to have a less-dominant presence of synchronous generators due to the incorporation of renewable generators interfaced by electronic power converters. A realistic picture of future power systems may still contain synchronous and non-synchronous generation. However, it is also reasonable to think in scenarios with 100% of non-synchronous generation, at least during a short time. For example, during some hours of the day. Transmission System Operators (TSOs) must also guarantee the stability of the system in such scenarios. Understanding the dynamics drive the stability of a large power system with 100% of non-synchronous generation remains an open question. Furthermore, the types of models to be used for stability analysis of this type of systems and how the converters should be operated are also open questions. Along these lines, the main objectives of this doctoral thesis are: • Analysis and identification of the relevant dynamics for stability analysis of power systems with 100% of non-synchronous generation. • Proposal of a reduced model for stability analysis of power systems with 100% of non-synchronous generation. • To provide recommendations to TSOs for the operation of electronic power converters to improve stability of power systems with 100% of non-synchronous generation.
