Conceptualising a grid resilience framework for renewable energy integration

Due to their variability and intermittency, renewable energy sources necessitate a robust and resilient grid framework. With increasing renewable integration in South Africa, grid instability and infrastructure vulnerability become significant challenges. This paper explores the complexities of the South African energy system while balancing operator requirements within the Southern African region's unique context. Through a multidisciplinary approach, it develops a framework that includes various levels of renewable penetration. It proposes technical and operational solutions for ecological grid resilience. The framework draws from contemporary research, case studies, and energy system modelling, emphasizing advanced grid infrastructure, smart grid technologies, flexible operations, real-time monitoring, and predictive analytics. It provides practical insights for engineers, policymakers, and industry stakeholders to develop resilient energy systems, ensuring grid resilience and energy security in Southern Africa.
