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
