01 / Context
Overview
This ongoing transmission study uses the IEEE 39-bus system in PSS/E as a working platform for renewable integration. The work includes a validated power-flow model, N-1 contingency studies, and the addition of a 250 MW renewable plant.
Python scripts use the PSS/E APIs for model changes, contingency screening, P-Q analysis, and results extraction. The work also includes renewable dynamic models identified as REGCA1, REECA1, and REPCA1. Wider N-2, N-1-1, extreme-contingency, load-scenario, and voltage/VAr support assessments are listed as extensions, rather than completed findings.
My work
- Built and validated the IEEE 39-bus model and N-1 study cases.
- Integrated the 250 MW renewable plant with steady-state and dynamic models.
- Automated model changes, contingency screening, P-Q analysis, and results extraction using Python.
02 / Approach
Methods & diagrams
Network and operating point
Power-flow and N-1 cases establish the transmission-study starting point and the network response to the renewable addition.
Renewable-plant representation
The plant is represented with steady-state data and REGCA1, REECA1, and REPCA1 dynamic models, as recorded in the project summary.
Repeatable study scripts
Python scripts automate case changes, screening, capability analysis, and extraction of results for comparison.
Findings
- A reusable PSS/E model and Python study workflow have been assembled.
- Extended contingency and voltage-support studies remain part of the ongoing scope.
Scope & limitations
Power flow, N-1 screening, renewable-plant modeling, and Python automation form the documented core of this study. Extended contingency scenarios and voltage-support studies are ongoing.
