Unit Commitment Scheduling Including Transmission Constraints: a MILP Formulation
(Elsevier B.V., 2016-06)
The benefits of good scheduling of electrical units are widely known (De la Torre et al, 2008). In this paper, a new approach to account for the Security-Constrained Unit Commitment (SCUC) is presented. A model is developed ...
Preventive security-constrained DC-OPF formulation using power transmission distribution factors and line outage distribution factors
(2018)
his study proposes a very effective formulation to carry out the security-constrained direct current (DC)-based optimal power flow (OPF) problem using two linear factors: (i) the power transmission distribution factors ...
Security constrained optimal active power flow via network model and interior point method
