A Review on Grid-Connected PV System

2018

"The concept of injecting photovoltaic power into the utility grid has earned widespread acceptance in these days of renewable energy generation & distribution. Grid-connected inverters have evolved significantly with high diversity. Efficiency, size, weight, reliability etc. have all improved significantly with the development of modern and innovative inverter configurations and these factors have influenced the cost of producing inverters. This paper presents a literature review of the recent technological developments and trends in the Grid-Connected Photovoltaic Systems (GCPVS). In countries with high penetration of Distributed Generation (DG) resources, GCPVS have been shown to cause unwanted stress on the electrical grid. A review of the existing and future standards that addresses the technical challenges associated with the growing number of GCPVS is presented. Maximum Power Point Tracking (MPPT), Solar Tracking (ST) and the use of transform-less inverters can all lead to high efficiency gains of Photovoltaic (PV) systems while ensuring minimal interference with the grid. Inverters that support ancillary services like reactive power control, frequency regulation and energy storage are critical for mitigating the challenges caused by the growing adoption of GCPVS.

SALIENT FEATURES OF GRID-CONNECTED PHOTOVOLTAIC SYSTEM AND ITS IMPACT ON POWER SUPPLY

2014

Solar energy is available to the world for free of cost from millions of years and it is a basic energy source to the mankind. It is also one of largest energy source to the mankind. PV systems are a relative new technology. The operational experience with PV systems itself is at an acceptable high level and today’s installed PV systems are of a good quality and are able to operate without any problems for many years. The price level of the PV modules and the Balance of System costs (inverter included) have decreased significantly. This energy is available all around the world in large quantity. When this energy is collected by the solar PV cells it is in the small power with the D.C. supply, which is not compatible with the existing grid in the world. There is an inverter and the converter stage comes before this energy can used. Grid interactive PV systems can vary substantially in size.

Technical Issues in Grid Connected Solar Photovoltaic Roof Top system: A Review

International Journal For Research In Applied Science & Engineering Technology, 2020

The worldwide depletion of fossil-fuel resources has necessitated an immediate search for renewable energy sources to satisfy tomorrow's demand. Present expectations for renewable portfolios are modifying power systems by replacing conventional generation with clean energy options such as photovoltaic (PV) systems. Solar energy is a clean, inexhaustible and environmentally sustainable fuel among all green energy choices. For the sustainable growth of electric power, the use of green energy systems such as SPV power plants offers reliable power throughout the day. If the SPV power plant is installed into an interactive grid system, the power during non-solar time is imported from the grid and the surplus energy during solar time is fed into the grid. As a result, in order to meet load demand, grid-connected power system networks are now being deployed, integrating solar and utility grids, where the grid serves as an energy storage facility. In this review article the technical issues associated with grid integrated roof-top PV systems and current scenario of generation of solar power in India is discussed. I. INTRODUCTION Renewable energy initiatives are primarily developed to address the rising energy needs of rural communities and the promotion of decentralised and hybrid growth in order to curb the growing movement of rural residents to urban areas in search of better living conditions. Due to the exponential rise in energy demand, the exponential decline of earth's fuel supplies, global warming and the harm to existence of traditional energy sources, it is important to transition into renewable energy sources. Promoting and improving renewable green energy sources, such as solar energy generation, wind energy, hydropower, bioenergy and geothermal energy, etc., has drawn the attention of government and private stakeholders to meet the rising need for energy and technology growth for the future [8]. India is endowed with large amounts of solar radiation, a diversity of crops and climatic conditions, large coastal areas and future river systems that offer the best conditions for developing renewable energy. The various Distributed Generations (DGs) which are renewable in nature with a wide spectrum range of few kW and 20 MW are gradually involved and rapidly developing and the interest of researchers and utilities has been seen. Among several renewable energy sources, the DG SPV system is the most cost-effective option for future energy needs [1]. Due to many benefits of solar PV systems, such as the universal availability of solar energy in the world, cost-free, ample, low maintenance. Solar PV DGs collect energy from the sun [1].
