Unlike a conventional generator that is often modeled as a PV node (set the generator’s terminal voltage and its active power output constant), a photovoltaic generator is operated as a PQ node (set the photovoltaic generator’s active power and reactive power outputs constant).
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 (PV) power generation has developed very rapidly worldwide in the recent years. There is a possibility that the PV power generation will switch from an auxiliary power supply, as of today, to a main power source in many power grids in the future.
