Abstract
With the frequent occurrence of electromechanical oscillation in the power systems, the fast response characteristics of the photovoltaic (PV) power generation system are used to actively damp the electromechanical oscillation in the power system. The proportion and position of PV generations in the system are usually different, therefore, the dynamic process of PV damping the grid electromechanical oscillation will also be changed.  This paper divides the conventional system into two parts: the power system and the infinite power grid, the steady-state output of the PV generation system is equivalent to the active output current Id0 and the reactive output current Iq0. The analysis conclusions of these two parts shows that: the inertia level, synchronization and damping effect of the conventional system will increase with the increase of Id0, and first decrease with the increase of Iq0, then increase rapidly, and then decrease. Moreover, the closer the PV module to the electromechanical oscillation source, the better the oscillation damping effect. Finally, this paper verifies the conclusion correctness through MATLAB/Simulink.
