“…There have been many significant works done by researchers around the world on the Hybrid power system with renewable energy, which are either off-grid [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] or grid-connected [26][27][28][29][30][31][32][33]. In [7], Groppi et al focused on the hybrid storage (battery plus hydrogen) system while planning a smart energy system to ensure economic and environmental benefits.…”

Analysis of Techno-Economic-Environmental Suitability of an Isolated Microgrid System Located in a Remote Island of Bangladesh

Following a rise in population, load demand is increasing even in the remote areas and islands of Bangladesh. Being an island that is also far from the mainland of Bangladesh, St. Martin’s is in need of electricity. As it has ample renewable energy resources, a renewable energy-based microgrid system seems to be the ultimate solution, considering the ever-increasing price of diesel fuel. This study proposes a microgrid system and tests its technical and economic feasibility in that area. All possible configurations have been simulated to try and find the optimal system for the island, which would be eco-friendly and economical with and without considering renewable energy options. The existing power supply configuration has also been compared to the best system after analyzing and investigating all technical and economic feasibility. Sensitivity and risk analysis between different cases provide added value to this study. The results show that the current diesel-based system is not viable for the island’s people, but rather a heavy burden to them due to the high cost of per unit electricity and the net present cost. In contrast, a PV /Wind/Diesel/Battery hybrid microgrid appeared to be the most feasible system. The proposed system is found to be around 1.5 times and 28% inexpensive considering the net present cost and cost of energy, respectively, with a high (56%) share of renewable energy which reduces 23% carbon dioxide.

The introduction of environmental impact targets around the world has highlighted the need to adopt alternative sources of energy, which can supply the demand and mitigate the damage caused to the environment. Solar energy is one of the main sources of alternative energy, and is considered an abundant source of clean energy. However, to facilitate and encourage investors interested in the installation of photovoltaic energy systems for electricity production, it is essential to evaluate the factors that impact the economic viability of the projects. Therefore, the objective of this research is to present a systematic analytical framework, in order to identify and analyze the main factors that impact the financial feasibility of projects for the installation of photovoltaic energy plants. For this purpose, a systematic literature review was carried out, analyzing the main studies related to the topic and identifying the main factors that may financially affect investments in photovoltaic energy systems. From this review, 29 influencing factors were identified and separated into five categories, namely, location, economic, political, climatic and environmental, and technical factors. The main factors highlighted are the investment cost, power generation, operation and maintenance costs, solar radiation, lifetime, energy tariff, efficiency, electricity consumption, and interest and taxes. The results may assist policy makers, investors, researchers, and other stakeholders to identify the key factors that are being examined in the literature, and to evaluate which ones should be considered in their study to ensure the sustainable development of power generation through the solar source.

“…Therefore, a bidirectional communication system between the controller and devices forms an important aspect [18][19][20]. Apart from stability studies, the feasibility studies of microgrids include techno-commercial analysis [21,22]. Renewable energy sources are major components of these microgrids.…”

A stability study of interconnected microgrids is presented herein. This interconnection is vital to enhance the performance under dynamic conditions by providing mutual power support. The microgrids considered are based on three renewable energy sources, namely wind, solar, and biogas. The wind energy converting system (WECS) considered has a permanent magnet synchronous generator (PMSG) for conversion to electrical energy. A solar photovoltaic system (SPVS) with appropriate inverter has been incorporated. These two renewable energy sources are intermittent in nature. A biogas genset (BG) consisting of a biogas engine coupled with a synchronous generator is the third power source. The interconnection is by an AC line. Two interconnected microgrids, M1 and M2, are considered for mathematical modelling. Additionally, the microgrid M2 is also connected to the main grid for a limited but continuous power supply. Proportional integral (PI) controllers are used to control the frequency and voltage of the microgrids. Simulation studies are conducted on the system under step load disturbances and also for step changes in input power of wind/solar. It has been found that frequency and voltage deviations of the microgrids vanish under steady‐state conditions.
