FLC based Solar fed Micro Grid for Inertia and Damping Analysis with Droop Control

As the production of photovoltaic electricity depends on power electronics, it lacks the inherent properties of natural inertia and damping. This paper takes as its research object the grid integrated PV system with DC voltage control and establishes the fixed synchronous generator of the scheme to make the capacitance of the medium scaling contribution in the utility. The model is used to investigate the inertia, synchronization and damping properties of the system, as well as the rules governing these influences. The capacitor’s ability to store energy on a medium-term basis might result in a system that exhibits specific inertia characteristics. A greater inertia characteristic is shown by the system when the coefficient of drooping Dp reduces, from the viewpoint of the control parameters. The damping consequence of the arrangement is increased when Kp, the DC voltage external circle proportional coefficient, is increased. The system’s synchronization ability improves with an increase in the DC voltage external loop fundamental constant Ki. MATLAB/Simulink simulations are also used to ensure that the theoretical analysis findings are valid before they can be implemented
