An Accelerated-Decomposition Approach for Security-Constrained Unit Commitment with Corrective Network Reconfiguration- Part II: Results and Discussion
Abstract
This paper presents a novel approach to handle the computational complexity in security-constrained unit commitment (SCUC) with corrective network reconfiguration (CNR) to harness the flexibility in transmission networks. This is achieved with consideration of scalability through decomposing the SCUC/SCUC-CNR formulation and then fast screening non-critical sub-problems. This is compared against the extensive formulations of SCUC and SCUC-CNR to show the advantages of the proposed typical-decomposition and accelerated-decomposition approaches to SCUC and SCUC-CNR respectively. Simulation results on the IEEE 24-bus system show that the proposed methods are substantially faster without the loss in solution quality. The proposed accelerated-decomposition approaches can be implemented for large power systems as they have great performance in the scalability tests on the IEEE 73-bus system and the Polish system when compared against the respective extensive formulations and typical-decomposition approaches. Overall, a dynamic post-contingency network can substantially alleviate network congestion and lead to a lower optimal cost.
