LArge Res Integration Stability Analysis - Slovenian network study
Due to the massive development of digital controls and power electronic devices, replacing conventional sources, loads and network devices (FACTS, HVDC, BESS), the study of the stability of the system becomes more and more complex. Existing and new stability phenomena are impacted by those changes, and requires appropriated data, methods, and tools. The Slovenian network will experience in the next 10 years a high growth of electricity demand, decreasing inertia due to an high level of RES penetration (40% in energy coverage), and an increasing level of cross border exchanges. It is fundamental that stability issues are tackled in network planning exercises. In other CRESYM projects such as Harmony and BiGER, the existing modelling assumptions used for stability are tackled and new methods are proposed, but real network cases and TSO procedures are required to validate those future solutions. Hence, the aim of this project focusing on the future Slovenian network with a high penetration level of RES is to:
- analyse instability issues (especially inertia studies and frequency stability and new instabilities) with the current tools and methods,
- understand how those tools are limited for such analysis.
- and finally test new methods and simulation approaches developed in BiGER and Harmony projects.
