The analog solar cell voltage stabilizer depicted in the circuit below regulates the output current such that the input voltage U_I U I stays at a fixed voltage programmed via the voltage divider. This lets us then choose an input voltage close to the MPP of the solar cell.
It can be observed that solar-PV systems improve the voltage stability by enabling more reactive power reserve ( Qs - QL = 615 MVAr) which improves the stability margin ( ( Vo-Vcr )/ Vo ) = 39% of the system in comparison to SGs. Fig. 25 illustrates the reactive power output at the PCC and the terminal voltage of solar-PV systems and SGs.
Solar dependence on the environment affects the change in output values in hybrid plant systems, resulting in easy damage to both domestic and industrial appliances or in battery storage systems, so a mechanism is needed to stabilize the output voltage supplied to the battery or load.
Results from the testing of this device indicate that the buck-boost converter is able to stabilize output output from solar panels with a 14.4 volt set of points. The average efficiency obtained at buck-converter converter testing at buck mode is 85.4 %. On boost mode is 80%. On buck-boost mode is 79.2%.
This paper investigated the impact of large-scale solar-PV generation on long-term voltage stability. A rigorous theoretical analysis was performed with a simple test system to compare the LTVS impact of the solar-PV generation with the SG. Then the Nordic test system was used to conduct a system wide LTVS study with solar-PV generation.
The solar-PV system with high reactive power gain ( Kq = 4.5) increases its reactive power output (Q = 378 MVAr) just after tripping of the Line-1 while increasing the terminal voltage (V6 = 0.953 p.u.) resulting in an increase of bus-4 voltage (V4 = 0.937 p.u.).
