    Microgrid is a part of the power distribution system which uses renewable energy based of power generation connected to the grid system. Multi energy power generation is composed of renewable energy systems including photovoltaic, wind turbine, energy storage and local loads. Testbed of a microgrid system is the technique to ensure stable operation during faults and various network disturbances in grid and islanding connected mode. In this paper the microgrid using renewable energy consist of a 3 kW photovoltaic, with 30 pieces of 12V for 100Ah battery bank, DC/DC converter, charge controller for battery, single phase DC/AC inverter and various loads (resistor, capacitor, inductor) are develop. The AC buses 240V voltage include with isolation transformer to simulate the grid voltage level by Matlab/Simulink software

    1 online resource (viii, 59 pages) : charts (some colour)Includes abstract.Includes bibliographical references (pages 52-59).In this study, conversion of Solar Photovoltaic (PV) energy to increase sustainable energy and increase system efficiency is being studied. During the process, both stand-alone mode and grid connected mode microgrid with energy storage system (ESS) have been tested in a simulation environment. Their transition from one mode to another have been discussed for research purpose. Solar photovoltaic PV modules, energy storage devices (Battery), power electronics converters are used to validate the desired results. The study of stand-alone to grid-connected systems will be analyzed and tuned for a stable system performance. During the tuning, the voltage and the frequency are the key driving parameters to be controlled and evaluated. Also, the study of grid connected configurations will be conducted and then both systems will be compiled together using a switching property. The aim is to work on control system for creating the transition in the systems. The study is tested with MATLAB/Simulink platform-based simulations. The major focus will be on the control mechanism of the inverters in both modes, specifically for this study

    A large amount of energy produced is directly consumed in the form of electricity. This need for energy is continuously growing and leading to new ways to make efficient use of it. When we talk about using energy efficiently, the idea of a passive house system kicks in, which essentially focuses on reducing energy use for space heating or cooling in a house. The main idea is to reduce the energy consumption of the house as well as reducing its impact on the environment when the occupants are using the house. The first phase of the research shows the dynamic modelling of an energy-efficient home that works on the principles and guidelines of a passive house using the EnergyPlus simulation engine. A renewable energy system has been developed for the passive house, which is located at Flat Rock, St John’s, NL Canada. The overall design has been simulated using MATLAB/Simulink environment packages. The dynamic simulation indicates that the system gives promising results. In the second phase, a detailed simulation of a renewable energy system using various software and efficient energy management techniques are presented. Finally, for experimental validation, an open-source IoT platform named Ubidots smart home automation is used as Human Machine Interface (HMI) server, an ESP32 Thing microcontroller board as a Master Logic Controller (MLC) where all sensors and output devices such as power meter, relays are connected for data acquisition and control
