“…Such inverters may offer the control of active and reactive power and additional functionalities for PQ improvement. For instance, in [24] and [26] the authors proposed the method of controlling a three-phase, three-wire PV inverter, which, apart from supplying active and reactive power to the grid, can be used to reduce harmonic currents generated by non-linear loads.…”

This paper concerns the mitigation of voltage disturbances deteriorating power quality and disrupting the operation of LV distribution grids due to the high penetration of PV energy sources in prosumer installations. A novel control strategy for 3-phase 4-wire PV inverters is proposed, which ensures the transmission of PV active power and simultaneous compensation of load unbalance and reactive power, making the prosumer installation balanced and purely active. It results in the balance of phase voltages and the mitigation of their variability. Unlike other methods used for voltage regulation in LV grids, the proposed solution contributes to the reduction in losses, is simple, and does not require additional costs. In the paper, a control algorithm for the PV inverter is described. Its effectiveness was tested by simulation using a model of the real LV distribution grid developed in the PSCAD/EMTDC program. The results of the simulations are presented and evaluated.

“…In this section, several kinds of multilevel inverters are compared on the basis of output voltage produced, the number of switches used, voltage sources used, IGBT devices used, total standing voltage (TSV), and the THD of various configurations, as given in Table 2. The MLI circuit proposed in [3,6] produces eleven levels of output voltage with different switch counts. In [11], the proposed topologies produce thirteen levels of output voltage, whereas the THD is reduced.…”

“…The input voltage can be boosted by synthesizing capacitor voltage [5]. Integrating the solar PV system with the inverter is the main goal of the power quality improvement, and the performance of an asymmetric multilevel inverter with different PWM approaches for harmonic suppression is also examined [6]. Three induction motors are driven by a cascaded multilevel inverter using a hybrid control approach.…”

This paper deals with the implementation of a reduced multilevel connections (RMC) as Voltage Source Converter (VSC) in Shunt Active Power Filter (SAPF) for harmonic mitigation in Power system. The design mainly focuses on the voltage source converter of SAPF. The developed modular structure produces 9,11,13,15,17,19,21,23,25,27,29,31 output levels using symmetric and asymmetric PV sources. This paper mainly focuses on a robust design of power circuit (RMC) and control circuit (SHE controller) for obtaining required voltage levels. Hence, to design a 27-level inverter, the traditional clamped topology requires 52 switches, the Cascaded H bridge (CHB) topology requires 52 switches and in the proposed RMC only 12 IGBTs are needed to produce 27 level. An added advantage of these topologies are they produce less total harmonic distortion by increasing the output levels. The design includes a comparison of 27-level reduced multilevel connections (RMC) topologies suitable for asymmetric input sources from solar photovoltaics (SPV). Further the loss calculation and the cost analysis are done to make the inverter superior than the conventional topologies. The implementation of RMC with the selective harmonic elimination method mitigates harmonics in the system. The proposed system is modeled using MATLAB/Simulink. An Experimental setup of the suggested SAPF is established and experimentally investigated. A 3 KWp solar PV plant is used to feed the DC input to the developed prototype. Based on the findings, it can be concluded that the suggested inverter reduces the harmonics, compensates reactive power, improves power quality, lessens the components, lessens the size and reduces the cost.
