IEEE TEC East Tennessee Chapter Guest Lecture with Shaked Regev - Fast Transmission-Constrained Unit Commitment

#rruc,#fast #transmission

We propose an extension of Relax-and-Round Unit Commitment (RRUC) that is capable of committing generating units for larger problems faster than conventional methods, while staying within intertemporal and spatial megavolt-ampere constraints. We demonstrate the performance of RRUC using synthetic congestible test systems ranging from 100 to 20,000 buses. RRUC consistently finds low-cost solutions, independent of the problem size, and its run time increases sub-quadratically in the number of buses. RRUC can solve the full alternating current optimal power flow (ACOPF) 100 bus system in less than a second and the 20,000-bus system in 7 minutes. In contrast, a leading state of the art solver cannot find a feasible solution to the full ACOPF 100 bus system in 15 minutes.
