Data-Driven Modeling of Frequency Dynamics Observed in Operating Microgrids: A South African University Campus Case Study
Maritz, Jacques; Gorjão, Leonardo Rydin; Bester, P. Armand; Esterhuysen, Nicolaas; Erasmus, Stefaans; Riekert, Stephanus; Immelman, Reuben; Geldenhuys, Tiaan; Viljoen, Alexandra; Bodenstein, Charl (Peer reviewed; Journal article, 2024)South Africa has been experiencing an energy crisis since 2007. Utility loadshedding became the main control for under-frequency events due to a mismatch in generation and consumption. Rolling blackouts are further supported ... -
The stochastic nature of power-grid frequency in South Africa
Gorjão, Leonardo Rydin; Maritz, Jacques (Journal article, 2023)In this work, we explore two mechanisms that explain non-Gaussian behaviour of power-grid frequency recordings in the South African grid. We make use of a Fokker–Planck approach to power-grid frequency that yields a direct ...
