Quantum Annealing With Integer Slack Variables for Grid PartitioningIEEE Transactions on Power Systems - Tập 38 Số 2 - Trang 1747-1750 - 2023
Dawei Wang, Kedi Zheng, Fei Teng, Qixin Chen
Quantum annealing (QA) can be used to efficiently solve quadratic unconstrained
binary optimization (QUBO) problems. Grid partitioning (GP), which is a classic
NP-hard integer programming problem, can potentially be solved much faster using
QA. However, inequality constraints in the GP optimization model are difficult
to handle. In this study, a novel solution framework based on QA is proposed for... hiện toàn bộ

Transmission capacity: availability, maximum transfer and reliabilityIEEE Transactions on Power Systems - Tập 17 Số 3 - Trang 843-849 - 2002
A.M. Leite da Silva, J.G. de Carvalho Costa, L.A. da Fonseca Manso, G.J. Anders
The available transfer capability (ATC) is an important parameter for all
companies participating in power transaction activities. The main objective of
this work is to propose a new methodology to determine the best points in the
system to add new agents (sellers and buyers), in order to maximize the ATC,
without violating a pre-established reliability level. In the process, the ATC
probability d... hiện toàn bộ

Marginal pricing of harmonic injections: an analysis of the resulting paymentsIEEE Transactions on Power Systems - Tập 17 Số 3 - Trang 640-645 - 2002
P.J. Talacek, N.R. Watson
Marginal pricing of harmonic injections can be shown to encourage each member of
the network to independently act in such a way that the harmonic profile of the
system is optimized. A problem encountered with marginal pricing is that loads
can be charged complex amounts for their injections. This paper demonstrates
that the real part of the amount charged for any injection reflects the
"in-phase" ... hiện toàn bộ

Simultaneous Scheduling of Multiple Frequency Services in Stochastic Unit CommitmentIEEE Transactions on Power Systems - Tập 34 Số 5 - Trang 3858-3868 - 2019
Luis Badesa, Fei Teng, Goran Strbac
The reduced level of system inertia in low-carbon power grids increases the need
for alternative frequency services. However, simultaneously optimizing the
provision of these services in the scheduling process, subject to significant
uncertainty, is a complex task given the challenge of linking the steady-state
optimization with frequency dynamics. This paper proposes a novel
frequency-constrained... hiện toàn bộ
