“…Finally, few studies considered marine-based energy sources as renewable HRES-OFF sources. Two studies evaluated wave energy [15,68] and three considered tidal energy [41,69,70]. One study analyzed the flywheel as an energy storage system in combination with batteries, taking advantage of the high energy density that this system provides and the high depth of discharge, which are favorable characteristics in the transition between renewable energy sources and the storage system.…”

“…Seven investigations analyzed HRES-OFF in communities with more than 20,000 inhabitants, six of these on islands and one continental. The study with the largest number of inhabitants was on the island of Sandwip in Bangladesh (Figure 5), although this study did not represent the highest daily demand for electrical energy with 93,000 kWh/d [70]. The study that represented the highest level of energy consumption was that of [44], in which the authors considered five energy demand scenarios for Cozumel Island, Mexico, in 2018, 2020, 2024, 2035 and 2050.…”

Off-Grid Hybrid Electrical Generation Systems in Remote Communities: Trends and Characteristics in Sustainability Solutions

The objective of this review is to present the characteristics and trends of hybrid renewable energy systems for remote off-grid communities. Traditionally, remote off-grid communities have used diesel oil-based systems to generate electricity. Increased technological options and lower costs have resulted in the adoption of hybrid renewable energy-based systems. The evaluated 168 studies from the period 2002–2019 considered energy developments in Asia, northern Europe, Africa and South America, with the great majority in the northern hemisphere (n = 152, 90.5%). Many of the studied systems were located in tropical (44.1%) and subtropical areas (31.0%). Our review shows that most of the studied approaches combined photovoltaic (PV) and wind energy and that diesel generators are the preferred backup system (61.3%), while batteries are the preferred method of energy storage (80.4%). Communities far from coasts have more options for renewable energy sources, such as biogas. Although half the studies were related to communities with access to marine-based renewable energy resources, their use was only referred to in fifteen studies. In terms of trends, the studies show a mature development of PV and wind-power technology for off-grid hybrid systems independent of the latitude, which is preferred as they are proven and accessible methods. The preferred storage method is batteries, and diesel is the preferred backup system given the low efficiency of PV and the intermittent character of wind power.

A techno-economic analysis of a hybrid PV-Diesel mini-grid system in rural Bangladesh is presented in this study. The case-study is done using data from Patar Char village in Patuakhali district of Bangladesh, considering non-electrified households. HOMER simulation compares three system designs: Hybrid PV-Diesel-Battery, PV-Battery, and Diesel-Battery. Hybrid PV-Diesel-Battery system yielded optimum results in terms of the lower cost of energy (COE) of around USD 0.182/kWh. Overall carbon emission of this system is around 307 kg/year, which is lower than the Diesel-Battery system, but higher than PV-Battery system. A sensitivity analysis of PV-Diesel-Battery system is performed, by considering and varying some of the indicators to prove system sustainability and feasibility. The impact of price variability in diesel price, discount rate on COE, and total net present cost (TNPC) showed that PV-Diesel-Battery system is the most feasible option. Finally, a SWOT analysis is also presented to address participatory planning strategy of developing the hybrid energy system.

“…To achieve the best technical, financial, and environmental results, the design included a 50 kW diesel generator, a 12.4 kW PV, 11.1 kW wind turbines, and 18 batteries. This paper by Khan et al (2014) modelled a wind-PV-diesel generator-battery-tidal system to provide affordable electricity at Sandwip Island, in Bangladesh. That research revealed that the cost of electricity is minimum (0.069 $/kWh) for wind-PV-diesel and maximum (0.088 $/kWh) for tidal-wind-PV-diesel systems.…”

Ikuza Island in Tanzania faces lack of electricity. Therefore, this paper undertakes to design hybrid renewable energy sources for the island by specifically focusing on the buck-boost converter for the energy conversion from these renewable resources. The design of the bidirectional buck-boost converter for maximum power point tracking in off-grid hybrid renewable energy systems is multifaceted due to the inhomogeneity nature of the renewable energy sources. The bidirectional buck-boost converter, solar PV, wind-based generator, and energy storage system were designed and simulated in MATLAB/Simulink software. The designed system was tested with varying solar irradiance (750 to 1000 W/m2), temperature (20 to 25°C) and wind speed (150 to 157.5 radians/s) at constant load of 260 A while load variation involved varying the load current from 0 to 260 A at solar irradiance, temperature, and wind speed of 1000 W/m2, 25 °C and 157.5 radians/s, respectively. The variation of DC link bus voltage at different load conditions was reported. The simulation results show that the designed converter is able to maintain DC link voltage at 600 V. Moreover, the DC link voltage showed a maximum drop of approximately 0.67% during the constant load condition. Contrarily, a significant improvement is observed when the designed converter operates with the hybrid system of solar PV, PMSG-based wind generator and with energy storage system.
