Quantum Restricted Boltzmann Machine for Fast Unit Commitment

Abstract

Network-constrained unit commitment (UC) problems must be solved repeatedly to ensure power system reliability, yet face computational challenges from the growing system scale and fast response requirements. This letter proposes a quantum restricted Boltzmann machine (qRBM) method to accelerate UC solution by predicting solution patterns via quantum-hardware-compatible energy scoring and recovering optimal solutions through affine mapping. This method reduces the computation time for UC by 99.96%. Compared to existing quantum methods, it cuts the number of qubits needed by 276 times.
