Abstract— The active power filters eliminates the harmonic distortion caused by non-linear loads and improves the filtering efficiency performance when compared with the passive filters. This paper inspects about the analysis and simulation of a three phase four wire shunt active power f ilter under unbalanced and distorted load conditions. Current harmonic compensation is achieved by the imple...

The decrease in the price of solar photo voltaic (PV) panels has led to widespread adoption power as a renewable energy source, not only at grid level but also on roof tops residential buildings. PV produce direct current (DC) and can be readily used drive DC powered loads or charge batteries. Direct powering from is hindered by highly variant nature generation which depends number external wel...

Three-Phase four-wire distribution systems are facing severe power quality problems such as poor voltage regulation, high reactive power and harmonics current burden, load unbalancing, excessive neutral current, etc.This creates excessive neutral current both of fundamental and harmonic frequency and the neutral conductor gets overloaded. By integrating phase shifting into an extremely low zero...

The objective of the paper is the application of modular multilevel cascade converter based on double star bridge cells (DSBCs) to a Static synchronous Compensator (STATCOM), for reactive-power control. The power consumed by the heavy load will create an unsymmetrical current will reducing the quality of the power in the electrical grid. Due to the unsymmetrical current the electrical power in ...

Photo-voltaic (PV) tied Z-source Neutral-point clamped NPC-MLI (Z-NPC-MLI) is used in solar grid connected applications due to its improved performance related conservative inverters single stage power conversion. Though the Z source adaptation accepted technology, need for appropriate controller meet out grid/standalone requirements becoming necessary. The space vector pulse width modulation (...

Chapter 3 presents ANN based adaptive shunt passive filter, whose performance is found to be superior to fixed element shunt passive filter in harmonic and reactive compensation. However, the drawback is that it can provide only partial harmonic and reactive power compensation. Hence, an ANN based digital controller for active filter is developed. It compensates for the major portion of source ...

Varying weather specifically temperature and irradiation have a significant impact on Solar Photo Voltaic (SPV) output performance efficiency. Both the voltage power are unstable due to unwanted solar fuel variation. Therefore, Maximum Power Point Tracking (MPPT) plays an important role in case of SPV. Although different MPPT techniques imposed mitigate above-said issues, Perturb Observe (P&amp...
