Optimal PMU Placement via Quantum Optimization
Phasor Measurement Units (PMUs) are essential for real-time monitoring and improving grid observability. Determining the optimal PMU installation is critical, especially as the penetration of renewable energy resources increases, as the Optimal PMU Placement (OPMUP) can guarantee full system observability and reduce the installation cost.

On the Computational Viability of Quantum Optimization for PMU Placement [PDF]
Using optimal phasor measurement unit placement as a prototypical problem, we assess the computational viability of the current generation D-Wave Systems 2000Q quantum annealer for power systems design problems. We reformulate minimum dominating set for the annealer hardware, solve the reformulation for a standard set of IEEE test systems, and ...
