The Eskom Power Engineering Project (EPEP) is a Research, Testing, and Development NEC3 Professional Services Contract (PSC3) with Stellenbosch University to conduct operational, applied, fundamental, basic, and futuristic research to solve Eskom technical challenges around Renewables, Power System Planning and Operations and grid flexibility, by providing short- medium- and long-term technical solutions. The project addresses the following key research questions:

How does increased DER penetration affect maintenance scheduling for transmission infrastructure?

Increased DER penetration can reduce available maintenance windows due to grid congestion, complicating scheduling for essential transmission infrastructure upkeep.

What strategies can optimize maintenance efficiency in a congested grid with high levels of distributed generation?

Optimizing maintenance efficiency may require dynamic scheduling and advanced grid monitoring tools to balance generation, load, and maintenance needs amid growing distributed generation.

What are the implications of implementing annual curtailment measures for utility-scale solar PV and wind generation?

Annual curtailment measures for utility-scale PV and wind generation could help manage localized grid constraints but need careful design to avoid excessive energy losses.

How can curtailment strategies alleviate thermal and voltage constraints while maintaining grid stability?

Curtailment strategies can alleviate thermal and voltage issues by limiting generation during peak congestion, ensuring grid stability while maintaining energy flow.

What policies and practices can enhance grid reliability, resilience, and sustainability in light of DER integration?

Policies and practices focused on real-time grid monitoring, adaptive curtailment, and advanced planning can enhance the grid’s reliability, resilience, and sustainability as DERs become more prevalent.
