“…When compared to fossil fuels, renewable energy sources are pollution-free. Moreover, they are proven to be efficient both technically and environmentally [18]. Moreover, both access to energy and the growing energy crisis also directly affects economic growth, poverty, food production, education, health, clean water, well-being, and social security.…”

Given the recent increasing public focus on climate change issues, the share of electricity generation by renewable energy resources is increasing day by day. Increased renewables share will give us robust, sustainable, and climate-friendly energy systems for the future. Renewable energy penetration with the current power systems needs substantial research, planning and development which are now the primary focus throughout the world. In this study, a global renewable energy scenario is explained in detail in contrast with India, considering a case study elucidating the comprehensive review of the Gujarat state in India. The primary focus is on Gujarat state's actions plans to pertain to harvest renewable energy and maximizing its share in the energy mix. This study examines the actions and the policies adopted by the Gujarat government to overcome the potential barriers in order to support non-conventional as well as renewable energy development. It also investigates the numerous techno-economic and social constraints with possible solutions in promoting the deployment of upcoming renewable energy resources across Gujarat. This study can be used as a guideline for the government, policymakers, utilities, stakeholders and researchers to promote an increased renewable energy share in Gujarat as well as at other places around the globe.Energies 2020, 13, 40 2 of 30 Development Goals (SDGs) in January 2016, with 17 goals, which also aimed at achieving affordable and clean energy for all [4]. The government of India, under the SDG's India Index, is planning to deliver a complete view on the "social, economic, and environmental status of the country". The National Institution for Transforming India (NITI), shortly referred to as NITI Aayog, started a broad exercise to measure the progress of "India and its States towards the SDGs for 2030" [5]. As of 2010, the global power production from non-hydro renewable energy resources accounted for about 3.3%. The support from the new policies, there has been a growth in renewables, which increased to 5% by 2011 [6]. In the early days, most industrialized countries were considered as the roots of renewable energy innovation. However, in recent years, many developing countries, especially China and India, have become popular leaders in renewable energy use, as well as an innovation [7].Considering India's current energy situation, it should decrease the emissions from the energy sector in the future and is expected to curb the rise in temperatures to below 2 • C by 2100 to support the global effect indicated in the Paris agreement [8]. About 44% of India's rural households, i.e., 138 million, produce lighting through electricity, an efficient and reliable source of power. The remaining 55% primarily use kerosene, an inefficient source and its price have also become costly [9]. The depletion of natural resources and increasing demand is ubiquitous in all states of India. There is a shortage of energy, and hence, it slows down India's industrial and economic growth.

“…Therefore, a small unit of such a power system, called a microgrid (MG) or minigrid, can be considered as a viable solution to maintain continuity of power supply in the rural community for critical loads as well as support reduction in GHG emissions by utilising available renewable sources effectively. A microgrid is a low-voltage distribution network, and it can either be grid-connected or an off-grid autonomous system [1,4,5].…”

“…From the available research, it is evident that hybrid power systems with RE sources can be reliable, cost-economic, effective and more sustainable compared to either grid-connected or stand-alone generators utilising a single fossil fuel-based power source [1,4,5]. Many countries around the world such as, Bangladesh, India, South Africa, and Australia are currently doing in-depth research to deploy microgrid-based energy-efficient and reliable power systems for rural communities [4][5][6][7][8][9].…”

Due to high investment and maintenance costs, the government on Bangladesh is unable to provide sufficient support for grid extension and supplying electricity to remote or rural areas. The deficit in electricity introduces a crisis in powering irrigation systems, which influences negatively the country's dominant income-generating sector, agriculture. Islanded microgrids with solar photovoltaic (PV) cells is one of the most attractive solutions for providing power to rural areas due to their cost-effectiveness, reliability and environment-friendly attributes. Therefore, a techno-economic feasibility study has been undertaken to investigate the prospects of renewable energy-based islanded microgrids to support rural electrification to power both households and irrigation systems. Three case studies based on the operation time of irrigation pumps during the day are developed using the HOMER Pro Microgrid Analysis Tool to identify the optimised configurations for the proposed system. The optimised configurations are then assessed considering the performance matrices of the cost of electricity (COE), net present cost (NPC), greenhouse gas (GHG) emissions and renewable energy fraction (RF). From the analyses, it is perceived that the operation of irrigation pumps at different times of a day is a significant influence, and the optimum method considering techno-economical evaluation is to run the irrigation pumps during the daytime by solar PV. It is evident that the proposed islanded microgrid has significant potentialities in powering irrigation systems as well as rural electrification with low energy generation costs, a contribution to the reduction of global warming and to ameliorating the energy crisis in Bangladesh in order to achieve a sustainable future.

“…Microgrids based on integrated DGs, battery system, and local loads are an effective way to achieve active distribution networks to reduce the impact of large penetration of intermittent renewable energy making the power system cleaner, safe, and economical . A high number of MGs with various configurations are already in operation for providing the electricity to rural areas . Furthermore, standalone microgrid control is more complex than grid‐connected mode due to the high vulnerability to frequency and voltage deviations .…”

The increasing penetration of renewable energy resources in power systems has improved microgrid's implementation. A microgrid is a localized grouping of electricity sources and loads that normally operates connected to and synchronous with the traditional centralized grid but can disconnect and function autonomously as physical and economic conditions dictate. Main factors to control in a microgrid are mainly frequency and voltage regulation, energy management, operation, and control scheme. This high penetration of renewable generation systems with their intermittent nature and unpredictable output power fluctuations might cause many control problems and large frequency/voltage deviation in microgrid stand-alone operation. Thus, to maintain the microgrid stability, an efficient and highly reliable control scheme is required. In this paper, a newly proposed fuzzy logic-based robust control mechanism is used to stabilize the frequency and direct current bus voltages in large fluctuations caused by sudden changes in power generation or load side. Also, supercapacitor and battery energy storage system are used to stabilize direct current bus voltages. This proposed method ensures the system efficiency and stability by reducing the system complexity and transient time, minimizing the frequency deviations, and preventing synchronous generator units from surpassing their power ratings in response to these disruptions. Simulation results also validate the effectiveness of the proposed controller in comparison with previous techniques.
