Abstract

Solar energy is one of the most important and rapidly developing technologies in India. In recent years, India's attempts to increase the share of solar energy in electricity generation have led to the use of all renewable energy sources in electricity generation. It does not require fuel and has no negative impact on the environment. This research paper compared real-time data for off-grid and floating Photovoltaic (PV) systems. A stand-alone photovoltaic system assumes that a battery is used to store energy. He encountered a problem with the heating on the ground or on the roof, causing the panel's efficiency to drop. A floating solar panel is a novel solution to the problem of scarce land and rising panel temperatures in standalone systems. The efficiency of a floating PV system is higher than that of a stand-alone PV system because the water constantly cools the temperature of the floating solar panel. This paper explored the performance of both standalone and floating PV modules. The systems used the Maximum Power Point Tracking (MPPT) approach and the simulations were performed in MATLAB. Other MPPT algorithms are available, but this is the one uses the Perturb and Observe (P & O) technique.

Abstract

India is a dynamically developing country in which 60% to 65% of the industry consumes electricity. Many Indian firms are improving their technology, so the demand and supply of electricity is growing. With the help of energy audits, it can reduce the gap between energy demand and supply as much as possible, which is good for all sectors and it can manage the maximum demand for energy in companies and improve the power factor by reducing energy losses and improving energy efficiency. This paper is a preliminary investigation by Vandana Global Limited, Raipur. Comprehensive load study of industries with 7000 KVA monthly contract demand, new loads have been introduced in this industry, highlighting the need for significant energy conservation measures. To evaluate the savings, a full energy audit must be carried out. After energy analysis of the monthly electricity bill, the four-month average power factor is 0.92, therefore the grid power factor can be increased as inductive loads are fewer. It can use the automatic reactive control panel to improving to the grid power factor by adjusting the required reactive power from the grid connected alternator. The system is effective due to cost savings, return on investment and profit. Time of Day (TOD) and conserve energy meter readings were used to measure demand control. Energy Audit energy efficiency solutions reduce energy waste and energy costs. In general, special attention was paid to reduce demand losses and energy costs. This paper recommends using genuine energy in the right place and organizing the use of energy through an energy audit.

Abstract

The use of electric vehicles is growing very rapidly, and more and more people are switching to electric vehicles as the problem of air pollution has become a concern in most parts of the world. In addition, the spike in fuel prices around the world has prompted people to opt for an alternative vehicle option other than conventional Internal Combustion Engine (ICE) vehicles. But as the number of electric vehicles increases, the need to install charging stations on a very large scale also increases. The main problem with conventional grid-based charging stations is that they increase the load on the main grid and affect the power quality of the local distribution network. This paper discusses the modeling and simulation of a hybrid electric vehicle charging station operating in multi-mode (i.e., grid-connected or Grid Power Connected Mode (GPCM) and solar-powered or Solar Power Connected Mode (SPCM). The Electric Vehicle (EV) charge controller automatically switches between GPCM and SPCM. With this hybrid electric vehicle charging station model, renewable energy can be integrated with the main grid to improve the efficiency and reliability of the electric vehicle charging station, so the Electric Vehicle Charging Station (EVCS) hybrid model can help to expand the electric vehicle charging network on a large scale. The simulation was performed using MATLAB 2016.

Abstract

Power quality problems in the distribution system can sometimes lead to unbalanced and uncontrolled conditions during operation. This situation can be overcome by estimating the parameters of the distribution system, thus solving the problem of load distribution. The presence of harmonic loads in the distribution system complicates the operation of the system and requires new algorithms to obtain a specific solution rather than an approximate solution. Taking all these aspects into account, this paper presents a new methodology based on decoupling by formulating intrinsic and mutual impedance networks and mathematical modeling of these networks along with ancillary methodology. This methodology is applied to solve an unbalanced distribution system with 13 nodes and 11 harmonic loads connected in different parts of the system. The obtained results are confirmed by the existing literature methods.

Abstract

Energy consumption has increased dramatically and steps towards the energy efficiency goal and emphasizes that an energy audit is an ongoing operation. It addresses the feasible activities, such as how to conserve and efficiently use our limited resources, and identifies how it reduces the capacity and how to translate these efforts into reality. A plant or facility may undergo an energy audit to determine energy consumption and energy conservation practices, as well as where and how energy is used. Improved procedures, better tools, and more efficient equipment can help to save energy.
