“…The resonance limitation of a standard current controller operating under abnormal grid conditions was analysed and a control scheme of a 3-phase PV inverter was presented [5]. [6], present a current control inverter design that mitigates under-order harmonics. The complete design has been validated with experimental results and good agreement with the theoretical analysis of the whole system is observed.…”

In this study, the effects of harmonics on the quality of the electrical power produced by both types of inverters are compared in solar panel applications between pure sine wave and modified sine wave inverters. Additionally, a number of prior investigations into harmonics and inverters have been analyzed. This study was done to find the best kind of inverter to use with solar panels in order to increase the effectiveness and caliber of the electricity generated. Experimental research methodology is applied, with measurements of the electrical power quality produced by both types of inverters under the identical circumstances. According to the findings, the modified sine wave inverter has a higher THD power quality than the pure sine wave inverter. The modified sine wave's displacement power factor (DPF) cannot be more than one (one), but the pure sine wave's DPF is equal to the cos phi value. At a 200W load, the pure sine wave inverter has a power efficiency of 93.35% while the modified sine wave inverter has an efficiency of 81.50%. Given that modified sine waves have a higher harmonic influence, it may be said that pure sine wave inverters create electrical power of a higher quality. Therefore, it is highly advised to utilize a pure sine wave inverter for solar panel applications.

“…But it has the drawback that it requires a signal of synchronism for current processing and has poor dynamical response when line voltages are distorted. Dongare and Kalgunde (2017) proposed an adaptive filtering by integrating a proportional resonant controller. This has resulted in better performance in terms of dc offset removal and harmonics mitigation, but it does not have the capability to face abnormal grid conditions.…”

Purpose The purpose of this paper is to focus on two major areas of concern for the Photovoltaic (PV) system, i.e. power quality and maximum power point tracking (MPPT). Novel control strategies have been proposed for both these issues, and their respective superiorities over the existing techniques have been established. On the other hand, as far as MPPT is concerned, two limitations are found in the available techniques. One is the inability of effective MPPT in dynamic conditions where the environmental parameters changes very rapidly. Second one is the ineffective tracking of global maxima under partial shading conditions. Design/methodology/approach Here, modified Kalman filtering approach has been applied for estimating the reference current of active power filter, incorporated for power quality improvement. The proposed Kalman algorithm introduces a weighted matrix, which advances the estimated values of state variables. This paper presents a simple and enhanced model-based (MB) MPPT algorithm that has the capability of tracking MPPT effectively in both these working conditions. The proposed MB algorithm uses the mathematical modelling, and based on precised estimation of parameters, it pre-determines the MPP analytically. Findings It has been tested successfully for dynamic variations of insolation, temperature and partial shading, where all these three parameters are rigorously varied over the full scale of practical values. The results have been also investigated experimentally and compared with the simulated one. A close matching of both the results has been shown through the plots, which validates the effectiveness of proposed algorithms. Originality/value This research paper is part of the original research work carried out in Lab. Simulated results are obtained in MATLAB/Simulink platform, whereas these are further validated experimentally on 2-KW panel constituted with all types of commercial products, namely, mono, poly and thin-film.
