Long-Term Dynamic Simulation Of Power Systems Using Python, Agent Based Modeling, And Time-Sequenced Power Flows, Thad Haines

Graduate Theses & Non-Theses

Automated controls facilitate reliable and efficient operation of modern power systems. Engineers employ computer simulations to develop, analyze, and tune such controls. Short-term dynamic, or transient, power system simulation is a useful and standardized power industry tool. Researchers have developed effective long-term dynamic (LTD) simulators, but there is not yet an industry standard computational method or software package for LTD simulation.

This work introduces a novel LTD simulation tool and provides examples of various engineering applications. The newly created software tool, Power System Long-Term Dynamic Simulator (PSLTDSim), uses a time-sequenced power flow (TSPF) technique to simulate LTD events. The TSPF …

Power System Simulation Using An Adaptive Modeling Framework, Matthew Stajcar

Graduate Theses & Non-Theses

Power system operation has changed significantly in the last several decades. Factors such as renewable energy integration and deregulation are major contributors to this change. In response, today’s power grid requires supplemental simulation techniques to ensure stable and reliable operation. One supplemental simulation technique includes a simulation tool that encompasses system dynamics of multiple time frames. This thesis proposes initial research of a power system simulation tool, Adaptive Modeling Framework (AMF), capable of modeling multiple dynamic characteristics including slow dynamics, such as transient stability, as well as long term dynamics (LTD), such as frequency regulation or voltage stability. Each power …
