Threephase transformer modeling for unbalanced
distribution power flow has not been successful in phase
variables. A satisfactory solution to this problem has been
developed earlier, using a hybrid of phase and sequence variables.
These models are not suitable for power flow methods which can

It is important to note that except 1, all other approaches
require a hybrid of phase and sequence variables. Keeping this
in view, the objective in this paper is to develop new pie
models for various transformer connections, which will allow
the use of pure phase variable approach. Although this mo[r]

Abstract
The reduction of the main energy requirements in the CO2 capture process that is re-boiler duty in
stripper section is important. Present study was focused on selection of better solvent concentration and
CO2 lean loading for CO2 capture process. Both coal and gas fired power plant flue gas[r]

In this paper, we study secondorder necessary optimality conditions for a discrete
optimal control problem with nonconvex cost functions and statecontrol constraints.
By establishing an abstract result on secondorder necessary optimality conditions for
a mathematical programming problem, we derive s[r]
