An analytical solution to the optimal power flow
(2002-03-01)
This letter presents an approach for a geometrical solution of an optimal power flow (OPF) problem for a two-bus system (slack and PV busses). The algebraic equations for the calculation of the Lagrange multipliers and for ...
Penalty-based nonlinear solver for optimal reactive power dispatch with discrete controls
(2013-04-15)
The optimal reactive dispatch problem is a nonlinear programming problem containing continuous and discrete control variables. Owing to the difficulty caused by discrete variables, this problem is usually solved assuming ...
