Overview

Entails a Microgrid Test Rig to support groundbreaking research and development and innovation around grid integration of renewable energy.

The UCT-WIND programme is developing an advanced microgrid test rig capable of simulating a wide range of interactions using additional modules such as inverters, battery emulators, and fault/grid-connection emulation tools. This infrastructure supports energy-efficiency research, potential collaborations with partners including the City of Cape Town, Eskom, UKZN, and Stellenbosch University, and provides opportunities for training, problem-solving, and validating Eskom IPP grid-integration models in a controlled laboratory environment. The work also aligns with national skills development through SANEDI.

Parallel unfunded and third-party-funded research includes power systems studies such as wind power forecasting, offshore wind modelling, and ancillary services for large IPPs. Technology development spans permanent magnet Vernier machines, axial flux switching generators, grid-forming inverters, and advanced filter design. Additional support is provided for emerging energy systems, including renewable-based EV charging power electronics and transformer-less DC microgrid concepts aimed at reducing infrastructure theft.

Projects and Prototypes

Alternating Flux Barrier Permanent Magnet Vernier Generator

  • AFB-PMVG uses magnetic gearing via flux modulation to enhance performance.
  • Provides much higher torque density than conventional PMSMs.
  • Features alternating flux barriers and permanent magnets for efficient energy conversion.
  • Enables compact, high-torque, low-speed operation.
  • Well-suited for renewable energy systems, especially wind power applications.
