Write a MATLAB code of Newton-Method for this problem.

Electrical grids are built to provide reliable and economical electrical energy to a variety of consumers. The steady-state operation of an electrical grid can be represented by set of non-linear algebraic equation (also known as power flow equations). An electrical power grid consists of thousands of transmission lines, hundreds of different types of generations, and loads (or consumers). Hence, it is not practical to seek an analytical solution when the grid is larger than a two-bus system. Let us consider an example from Fig.1, in which a coal-powered generator is connected by a transmission line with an impedance equal to R+jX to a residential society with power injections as P +jQ. Here. P and Q denotes the active and reactive powers, respectively. The voltage phasor at generator is denoted as VsZ0, while complex voltage at residential area is defined as V 28.
