LaRISA - Large Res Integration Stability Analysis

Project description

Reasons behind this project

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.

Other CRESYM projects such as Harmony and BiGER, tackle existing modelling assumptions used for stability and propose new methods, but real network cases are required to validate those future solutions.

In this respect, the Solvenian grid is a good case. it will experience in the next 10 years a high growth of electricity demand, decreasing inertia due to a high level of RES penetration (40% in energy coverage in Slovenia), increasing cross border exchanges. And as a result, stability risks must be carefully assessed in planning studies, with novel methodologies.

Project objectives

The aim of LaRISA 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.

Project members

LaRISA is a common project, performed by University of Ljubljana under the supervision of ELES
