Linear Current Flow Equations With Application to Distribution Systems Reconfiguration
Hamed Ahmadi,Jose R. Marti +1 more
TL;DR: In this paper, a set of linear current flow (LCF) equations are derived for distribution system (DS) analysis to find the nodal voltages, which is then used within the network reconfiguration problem for loss minimization.

A hybrid EP and SQP for dynamic economic dispatch with nonsmooth fuel cost function
TL;DR: In this paper, a hybrid methodology for solving dynamic economic dispatch (DED) is proposed, in such a way that a simple evolutionary programming (EP) is applied as a based level search, which can give a good direction to the optimal global region, and a local search sequential quadratic programming (SQP) is used as a fine tuning to determine the optimal solution at the final.
