Abstract
This paper presents the perturbation and observation (P & O) algorithm as maximum power point tracking (MPPT) method for the dynamical analysis of DC shunt motor fed by photovoltaic generator at different solar irradiance levels. At each solar intensity, the maximum power point of current/voltage (I/V) characteristic of the PV generator is achieved by perturbation and observation algorithm. The nonlinear behavior of (I/V) characteristics of the PV generator at various solar intensities and the magnetization curve of the ferromagnetic material of the DC shunt motor are described by high order polynomial mathematical expression. The dynamical analysis of the DC shunt motor fed by PV generator at different solar intensity has been carried out, also the dynamical analysis of DC shunt motor is investigated at a step change in solar intensity levels with fixed load at motor.

Summary
As the world population is increasing dramatically, the demand for electricity became one of the world’s largest concerns. Large-signal stability analysis has been carried out considering symmetrical three-phase to ground fault as a case study at the middle of one of the transmission lines when the PV generator is intensified with different solar irradiance levels. The complete system consists of an array of solar panels, a boost converter with PI and DC shunt motor with Fuzzy Logic controller (FLC)-as a voltage regulator. The dynamical and the steady-state behavior of hybrid powered DC series motor through PV and DC shunt generators are presented [4]. P & O technique is used for changing the duty cycle of the DC-DC buck-boost converter to keep the output voltage of DC-DC buck boost converter equal to the value of voltage at maximum power point of the I/V characteristic of PV generator. Appendix B presents the values of the numerical parameters of the system and presents the constants of the polynomials which approximate the output characteristics of the PV generator at three solar intensities levels
