Abstract
Photovoltaic power plants usually work in maximum power point tracking (MPPT) mode to maximize the output power that deliver to the grid. By increasing the number of installed PV plants, new challenges have emerged in the system such as overloading, overvoltages, and operation during voltage disturbances. So the need for increased ancillary services imposes power reserves in the photovoltaic systems. In this paper, a stable algorithm is used to operate in constant power generation (CPG) mode at the right side of the MPP without any instability problems by using I-V characteristic of the PV panel. A 100 KW PV system has been simulated in MATLAB/Simulink and the operation under a fast change in irradiance has been considered.
