Q Ref. = 1. It was obvious that the reactive power compensation by the PV inverter decreased the flow of reactive power in the grid to improve the performance of the system. Thus, the PV inverter was able to increase the reactive power required for heavy loads. values of Q Ref. = 0.5 and Q Ref. = 1.
To simulate the capability of reactive power control to cope with significant PV generation fluctuations, the PV generation profile for a partly cloudy summer day was chosen. The resulting PV generation factors are shown in Fig. 4.
Power flow analyses were conducted on MATLAB/Simulink for various reactive power modes of PV inverters to show the effect of the reactive power on the regulation of grid voltage, reduced the total harmonic distortion (THD), and maintain the power factor so as to improve the ability of the system to handle power.
As expected from the controller, the active power oscillation is zero during Sag I. On the other hand, the average of reactive power Q is increased to 2 kVAR. Consequently, the average injected apparent power () is equal to 2.4 kVA which is 77% of the apparent power during Normal operation ().
Across the world, efforts to support the energy transition and halt climate change have resulted in significant growth of the number of renewable distributed generators (DGs) installed over the last decade, among which photovoltaic (PV) systems are the fastest growing technology.
Furthermore, it has been shown that the centralized ANN successfully imitates the behavior of the ACOPF controller and hence, it is possible to control reactive power in PV systems using ANNs trained with ACOPF-generated input–output mappings.
