This express brief proposes two new iterative approaches for solving the power flow problem in direct current networks as efficient alternatives to the classical Gauss-Seidel and Newton-Raphson methods. The first approach ...

This express brief presents an approximation of the power flow problem for alternating-current (ac) and direct-current (dc) distribution networks by using a linear representation of the hyperbolic constraints i=p/v ↔ II∗ ...

This paper addresses the problem of optimal location and sizing of distributed generators (DGs) in direct-current (dc) power grids by using a mixed-integer nonlinear programming (MINLP) formulation. The reduction of the ...
