A Newton–Raphson-Based Sequential Power Flow Algorithm for Hybrid AC/DC Microgrids

Abstract: A hybrid ac/dc microgrid (MG) has the advantages of both ac and dc subgrids, and the operator should perform an accurate power flow analysis to ensure the MG's operational economy and ...

Finite Difference Approximations of Derivatives

First-order derivatives: n additional function calls are needed. Second-order derivatives based on gradient calls, when the "grd" module is specified (Dennis and Schnabel 1983): n additional gradient ...

Modified Newton-Raphson Method to Achieve Variable Step Hill-Climbing Algorithm for Maximum Power Point Tracking

Abstract: This work presents a derivation of the Newton-Raphson method, treated here as the Quasi-Newtonian (QN) algorithm. The QN has the same proprieties as the traditional Newton-Raphson method for ...
