Assessment of MPPT-Based Photovoltaic System: A Critical ReviewBy Hira Singh Sachdev, Raghu Chandra Garimella
Abstract: In this paper, new approaches are formulated to estimate the parameters and predict the maximum power generated by the PV module at maximum power point under varying environmental conditions. Maximum power point tracking technique is useful for extracting maximum power from PV cell. Here different techniques have been discussed and explained. Keywords: adder, irradiance, maximum power point (MPP), maximum power point tracking (MPPT), photovoltaic (PV)

Multifunctional Shunt Hybrid Power Filter and Thyristor Controlled Reactor for Distributed Generation Integration and Power Quality ImprovementBy Raghu Chandra Garimella, Sandeepthi Nandhyala, A.N.V.J. Rajagopal
Abstract: This project presents a multifunctional PV fed SHPF-TCR compensator for achieving maximum benefits from these grid-interfacing inverters. The inverter is controlled to perform as a multi-function device by incorporating active power filter functionality. An inverter can be used as power converter to insert the power created from RES to the grid, and shunt APF to reimburse load current harmonics. A SHPF-TCR compensator of a TCR and a SHPF has been …

Genetic Algorithm approach for the Position Control of Permanent Magnetic Synchronous MachineBy Raghu Chandra Garimella
Abstract: Permanent Magnetic Synchronous Motors (PMSM or Brushless DC Motor) are widely being used for many industrial applications because of their high efficiency, high torque and low volume. Research has conducted using genetic algorithm to develop a complete model of the BLDC motor and to design an optimal controller for its position control. Generally PID controller is being used for control purposes in many systems because of its simple structure and …

Modelling and Control of Higher Rating DC Motor with GA-Based Optimized PID ControllerBy Raghu Chandra Garimella, Atchyut Atchyut
Abstract: The usage of the common kind dc motors has its extended past. It has been used in the productions for numerous ages currently. They deliver humble means and exact method of controller. In addition, they have high efficiency and have a high starting torque versus falling speed characteristics which helps high starting torque and helps to prevent sudden load rise. But with such characteristics, the dc motors have some deficiencies …
