Chougule 2 1-2 Assistant Professor, Department of Electrical Engineering, DKTE, Ichalkaranji Email: dapatil@dkte.ac.in, pachougule@dkte.ac.in Abstract—The constant increase in electricity demand, as well as the depletion of fossil resources, has prompted research into alternate energy sources. Solar photovoltaic (PV) systems are gaining popularity in the renewable energy area due to their size, installation, and ability to operate both off and on the grid. As a result, solar roof tops with grid integration are gaining popularity in India. Many FACT devices must be interfaced with power electronics converters in order to integrate such renewable energy sources with the grid. Power quality requirements such as voltage imbalance, voltage regulation, power factor, harmonics, and others have become more significant since the development of power electronics switching devices. Overall, the distributed generation option increases power quality concerns when integrated with the grid. This paper focuses on opportunities, challenges and issues related to the grid integration of solar PV systems. Index Terms— Solar PV, Micro grid, FACT devices, Power quality. I. INTRODUCTION PV power generation is growing in India, despite the fact that solar photovoltaic cell generation is expensive due to the initial capital costs. As part of the National Solar Mission, the Government of India provides many incentives for solar power plants and also supports the policy regulatory structure in many states. The main advantages of solar grid integration are increased grid efficiency, stability and less transmission & distribution losses, etc. As a result, solar installations are carried out after a thorough survey to ensure that all necessary and sufficient parameters are fulfilled. The integration of a solar PV system with the grid, on the other hand, has always been difficult. The process of power transmission from renewable energy sources to the grid is known as renewable energy grid integration. The demand for energy in developing countries is growing at a rate of 5% each year. The geography of India makes it an excellent choice for solar energy harvesting. India's energy demand is expected to surge in the coming years due to its enormous population and economic activities [1]. India, as a rapidly developing nation, is currently undergoing transformation in solar market . As of December 2020, the country's total solar installed capacity was estimated to be 38.5 GW. In India, the National Solar Mission and policies have been declared, with the goal of achieving 100GW of installed solar capacity. This sector mostly consists of major solar projects and even larger solar utilities that produce power in a central location and deliver it to the grid. In comparison to other leading solar countries, India's rooftop solar systems are substantially lower in comparison with overall solar installations. [2]. In recent years, the government has introduced several of the laws and programs aimed at increasing the Grenze ID: 01.GIJET.9.1.510 © Grenze Scientific Society, 2023 Grenze International Journal of Engineering and Technology, Jan Issue
