In this study, a new controller based on the synchronous reference frame (SRF) in a photovoltraic (PV) panel supported three-phase unified power quality conditioner (PV-UPQC) is proposed to solve power quality problems in power systems. The serial and parallel active power filters fed with energy by PV panels are used together in the PV-UPQC system. In the proposed controller, measurement values are taken from four different points of the power system. The obtained values and DC voltage generated by PV panels are used to calculate the reference current and voltage values. PWM signals of switches used in active filters are produced using moving average filter and space vector-PWM. The algorithm used in both filters consists of two parts. The first is the mppt algorithm, in which the maximum voltage is obtained from the PV panels, and the second is the SRF-based proposed algorithm, where the reference current or voltage is obtained. Simulation and experimental studies of the proposed controller are applied. When the results obtained are examined, the proposed controller for three-phase PV-UPQC gives better results than the traditional SRF based controller in attenuation of harmonics in current and voltage.

In a modern power system with the increasing use of power electronics components, nonlinear loads connected to the grid cause power quality problems. To overcome the power quality problems, the parallel active power filter PAPF is used in power systems. In this study, the synchronous reference frame based a new control algorithm is proposed for the three-phase PAPF system. In the proposed control algorithm, synchronous reference frame SRF method and moving average filter MAF filter and space vector pulse width modulation SV-PWM technique are used to obtain low total harmonic distortion and high power factor. SRF method and MAF filter are used to calculate the reference current signal. SV-PWM technique is used to obtain the switching signals of active switches used in power filters. In the proposed algorithm, the number of measurements is reduced and performance is increased by using source ab currents and ab voltages without filter abc currents and abc voltages and load abc currents. Simulation studies of the proposed control algorithm have been tested using PSIM software. According to the simulation results, it is seen that the proposed control algorithm is more successful in eliminating the harmonics in the source current and compensating the reactive power than the other control method used in the literature.

“…This type of conditioner is used for unbalanced loads, reactive power compensation and to maintain the terminal voltage. It can be configured as multilevel [77,81,122,124], single-phase [78,79,121,123,125,126,127] and three-phase [80] UPQC and hence, this type of power quality conditioner can be considered as an A hybrid filter, a combination of shunt active and passive filter is shown in Fig.5.
