Forthcoming generation of industrial revolution completely changes the living standards of world population. In addition, growing phase of industrial revolution has more impact on grid system in terms of power demand and topology. Traditional power generating system adopts renewable source integration to deal with dynamic energy demand. Coalescing of green energy sources and industrial revolution hinders Power Quality of overall system. Industrial non linear loads and uncertain source of renewable energy units are the major causes of PQ degradation. To enhance PQ in renewable source interfaced grid system, ANFIS based ICC controller is proposed for shunt connected active filter. Photovoltaic Unit is optimally interfaced to grid for aiding PQ enhancing process. ICC based APF performance is investigated in MATLAB/SIMULINK platform. Proposed controller performance is analyzed for balance and unbalance load conditions. © 2018 the Author(s).

Substantial growth in modern innovations demands more power from utility. To cope with drastic power demand on grid renewable sources have been integrated. This makes more complex power system as these integrated sources more dynamic in nature. Intelligent usage of renewable sources leads to optimal and reliable power structure. This paper provides an optimal usage of renewable source for unified controlling action to compensate power quality issues on multi distribution feeders. Proposed Unified Multi Converter Controller (UMCC) effectively alleviates power quality issues like harmonics, imperfections in current and voltage on multi feeder. ANFIS based harmonics alleviation is studied and compared with traditional control error tuning. Here, Photovoltaic source is considered. Proposed three phase system is analyzed in MATLABSIMULINK platform with variable load and supply voltage conditions.

Enhancement of Power Quality in Multi Feeder Three Phase System with Photovoltaic fed ANFIS-Unified Multi Converter Controller

Growing population and industrialization demanding more power from the electrical utility. This causes drastic changes in the utility structure. The non conventional sources replaces the signing off conventional sources. The integration of non conventional sourses and different loads, hinders the power quality of the system. This paper uses Dynamic Shunt Active Fiter (DSAF) to mitigate the current hormonics and integrates the Renewable Energy units to grid. The controller performance is studied with conventional PI &amp; Fuzzy technique. The proposed system performance is studied in MATLAB/SIMULINK. © 2017 IEEE.

Mitigation of current harmonics in renewable source integrated grid topology with fuzzy based dynamic shunt active filter

The present modern power system is getting more complex and dynamic day by day. These Dynamic changes can be effectively handled by integrating renewable sources to the grid. The optimal usage of renewable sources will improve the overall performance of the electrical utility. Renewable energy sources and non-linear loads connected to grid have adverse effects on the power quality of the system. This paper presents I cosine ANFIS control based Dynamic Active Power Filter (DAPF) to improve the power quality of the grid at source side with effective integration of renewable sources. The model presents optimal usage of renewable sources and avoids the usage of battery by replacing with solar energy unit (SEU). DAPF fed by SEU and wind unit serves power to the load during power fluctuations from grid side. The performance of proposed model with I cosine ANFIS controller based DAPF is validated using MATLAB/SIMULINK. © 2016 Elsevier Ltd. All rights reserved.

Effective grid interfaced renewable sources with power quality improvement using dynamic active power filter

The power quality of interconnected grid is highly affected by the non linear loads and the interconnected renewable energy sources like wind and solar systems. The drastic changes in their input effectively change the grid parameters. This paper provides a novel method in which compensator continuously monitors the line parameters like voltage, currents, harmonics and reactive power to maintain the desired values at common connecting line (CCL). This paper utilizes the capabilities of hybrid Fuzzy and ZN PID Controlling of Dynamic Active Power Filter (DAPF) along with the Energy storage at dc link. The proposed model simulated in MATLAB/SIMULINK and at the grid common connecting line, the power factor and Total Harmonic Distortion values are much improved. © 2015 IEEE.

Hybrid fuzzy-ZN PID control based grid interfaced distribution level renewable energy source with power quality

This paper proposes the effective utilization of unified power quality conditioner (UPQC) for interconnecting the PV modules to the grid using power angle control (PAC) method. A shunt active power filter (APF) is used to evacuate the power from the photovoltaic module in addition to compensating the current harmonics, load unbalance and reactive power. To accomplish this the series APF in the UPQC is used for supplying a part or whole reactive power required by the load in addition to compensating the sag, swell, supply voltage unbalance and distortions. This is made possible by controlling the phase angle and magnitude of series injected voltage called power angle control method. The reactive power and voltage compensation technique introduces a phase shift between the load terminal voltage and source voltage. The transient due to sudden phase shift is minimized using step by step introduction of series compensation voltage. The proposed method effectively utilizes the shunt APF and series APF in the UPQC for interconnecting the PV module to the grid. The simulation results from MATLAB/SIMULINK are discussed to validate the developed method. © 2012 Elsevier Ltd. All rights reserved.
