This repository provides workflows for modeling, simulation, and stability assessment of renewable energy systems. It enables:
Study of high inverter based resource (IBR) penetration and grid stability
Comparison of grid-forming (GFM) vs. grid-following (GFL) controls
Evaluation of compliance with IEEE 2800, IRE, and national grid codes
Assessment of fault ride-through (FRT), frequency/voltage support, GFM control for Offshore wind with HVDC
Impedance/admittance scanning for oscillation and stability studies
⚡ Engineering Solutions
Grid-Forming BESS in Solar PV Plants
Description: A grid-forming battery energy storage system (GFM-BESS) stabilizes solar PV plants. Includes IEEE 2800 compliance tests for frequency and voltage support.
Grid-Forming Controls for Type-4 Wind Generators
Description: Implements two grid-forming strategies for wind generators: DC-link regulation (GGFM) and turbine inertia emulation (MGFM). Evaluated under fault ride-through (FRT) conditions.
Stability Assessment of Inverter-Based Resources
Description:Admittance scanning identifies oscillatory instabilities in IBR-dominated systems. Features Bode plots, eigenvalue tracking, and mode interaction analysis.
Multi-Terminal HVDC Systems for Offshore Wind
Description: Models multi-terminal VSC-HVDC systems for offshore wind integration. Tested under grid faults, asynchronous operation, and variation in grid strength.
Admittance-Based Stability of HVDC Links
Description: Demonstrates admittance scanning and stability analysis of a two-terminal VSC-HVDC system linking offshore wind farms to the grid.
