With the increased integration of PV generators into the grid, the system operators start to require PV generators have capabilities to stay online during the fault, and provide the active power and the reactive power supports when being required to do so.
By controlling the instantaneous three-phase inverter output voltages , and , the PV generator controls the active power output and the reactive power interchanges with the external grid.
A PV generator is modeled as a constant active power and reactive power source in power system steady state studies. When PV generation changes due to the ambient environment, the power system steady state studies do not investigate the transients of the power system caused by the change in PV generation.
There are two typical configurations of PV generator in power system applications, namely, single-stage and two-stage as shown in Fig. 1a, Fig. 1b. A single-stage PV generator uses only one converter to complete both the maximum power point tracking (MPPT) and the power grid connection.
Photovoltaic cells are a key component in solar power generation, so thorough research on output characteristics is of far-reaching importance. In this paper, an illumination model and a photovoltaic power station output power model were established, and simulation analysis was conducted using Matlab and other software.
To achieve such goals, it is essential to build credible simulation models for PV generators (Villegas Pico and Johnson, 2019). Like all the other dynamic components, such as generators or motors, a PV generator needs to be modeled dynamically for the purpose of power system dynamic simulation.
