[IEEE 2020 IEEE International Conference on Power Electronics, Smart Grid and Renewable Energy (PESGRE) - Cochin, India (2020.1.2-2020.1.4)] 2020 IEEE International Conference on Power Electronics, Smart Grid and Renewable Energy (PESGRE2020) - Power Optimized Architecture based Converter and Its Control for Single Phase Grid-Tied Solar Photovoltaic System
摘要： This paper proposes a power optimized based converter and its control for low voltage solar photovoltaic (PV) modules. For the grid tied solar PV system, the dc-bus voltage must be maintained more than a minimum level for its satisfactory working. In optimized architecture, each PV module is connected with a non isolated high gain DC-DC converter. These converters boost up the PV voltage as well as harvest the maximum solar energy. In the case of shadow, aging and fast change in solar insolation profile on each PV modules; it is able to harvest the maximum power. For maximum power harvesting, fuzzy logic control (FLC) is used. Each PV module with high gain DC-DC converter is connected at the common DC link. The DC power is converted into AC power by using voltage source Inverter (VSI). The VSC is controlled to stabilize dc-link voltage, synchronize with grid supply and to achieve low total harmonic distortion (THDs) in grid current under feeding non linear loads. For switching of a VSC, hysteresis control is used. Proposed model is developed using MATLAB 2015a and results are obtained under various operating conditions.

ICM based ANFIS MPPT controller for grid connected photovoltaic system
摘要： In this paper, grid-connected photovoltaic (PV) system is presented. PV system consists of a photovoltaic module, a boost converter, and voltage source inverter. ANFIS based ICM (Incremental Conductance Method) MPPT (Maximum Power Point Tracking) controller is utilized to produce gate signal for DC-DC boost converter. This controller is used for optimizing the total performance of the Photovoltaic system in turn the errors were reduced in Voltage Source Inverter (VSI). The grid-connected PV system performance is evaluated and harmonics occurred in the system are decreased. The proposed methodology is implemented in MATLAB/Simulink.

Performance investigation of grid integrated photovoltaic/wind energy systems using ANFIS based hybrid MPPT controller
摘要： The solar energy and wind energy are two natural, renewable energy resources for the mankind, for the energy supply without hassles that provided an avenue for its utilization. For the efficient of the resources, wind power generation is one of the options in association with a photovoltaic system for preserving solar energy. Hence the current system requires technology to be involved to control the operation to satisfy the major concern as initially a combinational hybrid system to keep track maximum power, DC voltage input and trade-off between renewable energy delivered for interconnections. The fluctuation in power for interconnection can be minimized by adaptive neuro fuzzy interference method (ANFIS) dependent maximum power point tracking (MPPT) system and microscopically trusted ANFIS based system. In this paper the hybrid MPPT controllers are compared that is with perturb-observe (P&O) and tip speed ratio (TSR) as one set of MPPT controller and another side incremental conductance method (ICM) and hill climb search (HCS) both the controllers are tested with the ANFIS. The proposed system to satisfy the defined objectives is modeled using MATLAB/SIMULINK software by connecting power grid system to inverter influenced by ANFIS controller.

[IEEE 2019 IEEE Industry Applications Society Annual Meeting - Baltimore, MD, USA (2019.9.29-2019.10.3)] 2019 IEEE Industry Applications Society Annual Meeting - Control of Single Phase Solar Photovoltaic Supply System
摘要： This work deals with the modified multilayer fifth order generalized integrator (MLFOGI) based grid tied single phase solar photovoltaic (PV) system employing fuzzy logic control (FLC) based maximum power point tracking (MPPT) algorithms. The MLFOGI is used to extract the fundamental component of grid voltage under polluted grid due to voltage sag, swell, harmonics, frequency variations and dc offsets. The FLC based MPPT is capable to extract optimum energy under change in weather conditions. It offers fast dynamic response under reduced PV voltage oscillation. The proposed system is developed on MATLAB 2018a and obtained results shows the feasibility of system control and Total Harmonics Distortions (THDs) of grid current are in acceptable limits as per IEEE-519 standard.
