Modeling and Validating System Dynamics in Saudi Synthetic Electric Grid

This paper introduces a modeling approach for creating a synthetic Saudi power grid, designed to simulate the transient dynamics of a real power grid. This synthetic grid model, created from open-source data, is available for open sharing and can be utilized for educational, and research purposes. The cases are built to match a detailed model of Saudi power system elements, Saudi code requirements, and statistical characteristics found in actual power grids. First, we describe how we built, tested, tuned, and validated this synthetic Saudi grid model by using statistics from currently available data. The CURENT Large-scale Testbed (LTB) and its ANDES package enabled power flow calculations, simulations of transient stability, and analysis of small-signal stability in transmission systems. Second, we describe our use of the ANDES package for dynamic simulation and testing, and our use of the LTB's AGVis package for grid visualization. This Saudi synthetic grid model has 223 buses that have been tested, tuned and validated to ensure that they are realistic and are practical for various studies. Also, it greatly enhances the diversity of existing collections of synthetic grids in the current literature.
