TL;DR: More feature changes compared to shaded and unshaded conditions are shown and the outcomes of partial shading with bypass diode and without bypass diodes on the I(V) and P(V%) traits of the photovoltaic panel are illustrated.
Abstract: Solar system is the high-quality and trustworthy supply of renewable energy. It is far contamination loose, fewer preservation, reusable and unfailing. The overall performance of photovoltaic (pv) machine is often stricken by radiation, module temperature and array configuration. The understanding of the shading impacts and their courting among the output powers of the pv array may be very essential in an effort to find a well overall performance of the pv system. partial shading is a case whilst the special modules of the array received a different irradiance level. This shadow can be both to expect due to extraordinary situations: neighbor constructing, close by tree or tough to are expecting due to clouds or building. the cause of this paper is to take a look at and illustrate the outcomes of partial shading with bypass diode and without bypass diode on the I(V) and P(V) traits of the photovoltaic panel. This is performed via using simulation using matlab/simulink. This paper shows more feature changes compared to shaded and unshaded conditions. All results are presented graphically.

TL;DR: In this paper, a new control strategy to improve the performance of shunt active power filter (SAPF) in three-phase four-wire system when operating under an unbalanced system is presented.
Abstract: This paper presents a new control strategy to improve the performance of shunt active power filter (SAPF) in three-phase four-wire system when operating under an unbalanced system. A control method based on the instantaneous power theory have been used and discussed. On the other side, a threedimensional hysteresis current controller is used to track the compensated current references. This scheme requires the service of a phased-locked loop (PLL) to make the system insensitive to the distortions that are generally present in the utility voltages. The performance of the proposed topology under the used control approach has been finally discussed through the obtained simulation results.

TL;DR: In this article, the effect of partial shading in solar roofed electric vehicle and the variation of output power with different patterns of shading were analyzed using MATLAB simulation, which showed the output power variation and the formation of multiple peaks due to shading.
Abstract: Renewable energy source is a clean source of energy which will cause no environmental impacts. The major drawback of renewable energy resource is their intermittency, moreover in solar energy shading is also an issue. Electric Vehicles help in reducing emission as it is fed from solar grids. Presently, automotive manufacturers have solar roofed vehicles for charging the vehicle battery while it is running or parked outdoors. As the vehicles are moving there is a possibility of solar panels being under complete shading or partial shading. Thus PV modules are used along with a MPPT to get the maximum power from panels. Shading is one major issue that will lead to the formation of local peak and global peak in the I-V and P-V curve, finally delivering a reduced power output. It causes serious problem for the MPPT algorithm as it will not be able to find the maximum power point. This paper focuses on the effect of partial shading in solar roofed electric vehicle and the variation of output power with different patterns of shading. Four Trina Solar TSM 250PA05.08A solar panels were connected in series along with a boost converter to analyse the shading conditions. MATLAB simulation is presented which shows the output power variation and the formation of multiple peaks due to shading.

TL;DR: In this article, the analysis of the production of rooftop on grid solar power plant in the government building with a case study in the Setjen KESDM was intended to determine the level of production of the solar power plants built and the parameters that influence it, which was conducted by comparing the real results with the simulation results using SAM software.
Abstract: In producing electrical energy, the solar module is affected by some factors, such as the solar radiation intensity, temperature, orientation and slope of the module, and shading that occurs during operation. The solar power plant of Setjen KESDM is coordinated at 6°10’53.73” south latitude and 106°49’24.61” east longitude, with a slope of 9.7°–10.0° and azimuth of -2.0° to -5.0° towards the north. It consists of five placement locations, including 11 th floor rooftop, T1, T2, T3, and L carports with a total capacity of 150 kWp. The analysis of the production of rooftop on grid solar power plant in the government building with a case study in the Setjen KESDM was intended to determine the level of production of the solar power plant built and the parameters that influence it, which was conducted by comparing the real results with the simulation results using SAM software. The energy production in 2017 was 118,259.3 kWh, in 2018 was 106,318.3 kWh, and in 2019 was 109,973.0 kWh. The highest production was obtained in September, October, and March every year due to the maximum solar radiation. The solar power plant on the 11 th floor rooftop was more maximal in producing energy for all positions of the sun than the solar power plant on the T1, T2, T3, and L carports because it was free of shading from buildings and trees. The output produced by the solar power plant of Setjen KESDM could not reach the maximum point because the location temperature was higher than the standard test conditions of the solar module.

TL;DR: In this paper, a combined sliding mode space vector modulation control of the shunt active power filter using robust harmonic extraction method is presented to improve the power quality such as current harmonics and reactive power compensation due to the nonlinear loads and unbalanced voltage source.
Abstract: This paper presents a combined sliding mode space vector modulation control of the shunt active power filter using robust harmonic extraction method to improve the power quality such as current harmonics and reactive power compensation due to the non-linear loads and unbalanced voltage source. To verify the validity of the analysis and the feasibility of the proposed control method a set of simulation tests have been conducted using Matlab/Simulink. A comparison between the conventional instantaneous powers method (PQ) used for harmonic extracting and the new PQ based on a multivariable extraction filter demonstrates the superiority of the proposed control scheme.

Abstract: In past few decades, solar energy plays a vital role in energy production among the different renewable energy resources. In shaded/unshaded photovoltaic (PV) systems, tracking of maximum power under different environmental conditions is provided by maximum power point tracking (MPPT). In recent years many works available on different types of MPPT techniques to track maximum power from PV systems with own pros and cons. This article comprehensively reviews the different traditional methods like perturb and observation (P&O), open circuit voltage (OCV), short circuit current (SCC), hill climbing (HC), incremental conductance (IC). Also recall the advanced MPPT techniques like particle swarm optimization (PSO), grey wolf optimization (GWO), cuckoo search (CS), artificial neural networks (ANN), fuzzy logic controller (FLC) available in literature. This review is conducted based on implementation, accuracy, tracking speed, cost, merits, and demerits of each technique. Traditional MPPT methods can’t able to track global maximum power point under partial shaded conditions and exhibits less efficiency when compared with advanced soft computing methods. Hybrid methods provide good efficiency and performance than traditional and advanced methods. Authors powerfully confirm that this article offers convenient information’s to enthusiastic engineers and new researchers those who are all working in solar PV systems.

TL;DR: In this article , a CM equivalent circuit is established to predict the electromagnetic interference (EMI) spectrum of the power port, and the parasitic parameters of the inductors are appropriately simplified to improve the efficiency of simulation.
Abstract: Common mode (CM) voltage and its resulting conducted CM electromagnetic disturbance emissions are strictly limited by regulations in photovoltaic (PV) current source inverters (CSIs). In order to study the CM conducted disturbance emission level of CSI, it is often necessary to establish a full circuit simulation model to predict the electromagnetic interference (EMI) spectrum of the power port, which consumes a lot of computing resources. As an alternative, analyzing and extracting the CM noise propagation path of the CSI and building the CM equivalent circuit model can save simulation time. In this paper, a CM equivalent circuit is established to predict the CM conducted EMI of CSI, and the influence of circuit parasitics is considered. In addition, the parasitic parameters of the inductors are extracted by the fitting method, and the equivalent circuit model is appropriately simplified to improve the efficiency of the simulation.
