Quantum Computing for Power Systems Optimisation

The Institute for Energy Systems at the University of Edinburgh invites applications for a PhD studentship in “Quantum Computing for Power Systems Optimisation”. The aim of the project will be to investigate whether quantum computing can support the large-scale optimal deployment and coordination of renewable generation, energy storage and demand flexibility within electrical power systems.

Power systems are undergoing a fundamental transition due to the large-scale integration of renewable generation, coupled with the electrification of transportation and heating. In the UK, it is expected there will be 15 million electric vehicles by 2030 and the deployment of 600,000 heat pumps per year from 2028. The optimal deployment and coordination of these technologies is critical for achieving a low-cost transition to a reliable decarbonised power system. However, the computational complexity of these problems is pushing against the limits of even state-of-the-art high-performance computing facilities. In addition, modelling approximations that have long been used for network optimisation are increasingly unsuitable for resources embedded within local distribution networks due to their nonlinear characteristics and extensive topologies.

Over the last 20 years, there has been significant progress in the development of quantum devices which offer a fundamentally new computing architecture compared with classical silicon-based computers. A major milestone towards this was the recent achievement of quantum supremacy with a 54-qubit device, i.e. the practical demonstration of a quantum computer solving a problem that would be infeasible for classical computers. This has been described as the start of the Noisy Intermediate-Scale Quantum (NISQ) era, where medium-scale quantum computers with moderate error rates for the first time can outperform classical computers for specific applications.

Motivated by these advances, the project will investigate the opportunity for problem-specific quantum computing algorithms to address the scalability challenges associated with power system optimisation problems that are key for the net-zero transition. This will bring together research across quantum computing, mathematical optimisation, and power systems engineering. The project will explore different quantum computing architectures (including gate-based and annealing-based), as well as hybrid approaches which leverage the complementary advantages of both classical and quantum computing.

*Please note that this position may be closed early if a suitable candidate is identified.
