Currently, solar energy is considered one of the most suitable options for overcoming the problems of fossil fuel depletion, and global warming. Also, the high costs associated to photovoltaic systems, renders the maximum utilization of solar cells, a fundamental and undeniable necessity. Technical-economic-environmental analysis, using HOMER software, was performed under four different scenarios: without the tracker, with the horizontal axis tracker, with the vertical axis tracker, and with the dual-axis tracker. Consequently, the best configuration was chosen for each scenario. The optimal system for all four scenarios, in the circumstance of disconnection from the grid, only involves the solar cells, while in the circumstance of connection to the grid; both the solar cells and the wind turbine are included. The results demonstrate that in the off grid situation, the scenario involving the use of a vertical axis tracker would be the most cost-effective, with the price of 0.812 $/kWh for energy produced, while the lowest price for producing one kg of hydrogen is $77.97 is attributable to the scenario without the use of a solar tracker. In the circumstance of being connected to the power grid, the scenario involving the use of a vertical axis tracker would be most cost-effective, with the price of each kWh of energy produced equal to $ 0.223. At the price of $29.33 per kilogram, the scenario involving the use of a vertical axis tracker would also be most suitable for the production of hydrogen. Another important fact revealed through the results, is the crucial role of dump load, in the provision of the heat required in an off-grid situation. However, dump load is not associated to heat provision in a grid-connected situation.

“…In 2018, all urban population and 100% of all rural households with more than 20 households had access to electricity. This year, Iran's required electricity energy was supplied by power plants affiliated with the Ministry of Energy, large industries, and the private sector, including 25 steam power plants, 70 gas plants, 25 distributed generation units, 28 combined cycle power plants, 45 diesel power plants, 59 hydraulic power plants (large, medium, small, and mini), 270 wind turbines, 50 photovoltaic units, biogas power plants, and 2 thermal recycling power plants owned by the private sector 9 . Also, large industries have 5 steam power plants, and 16 gas plants.…”

Nowadays, due to the increasing energy demand in different industry, agriculture, and household sectors, great importance is attached to energy portfolio and generation/consumption in macrolevel planning. A viable approach to power generation planning is the environmental assessment of the power generation process. This study employs life cycle assessment based on Eco-Indicator 99 methodology which analyzes midpoint and endpoint impacts. Energy impact evaluation is based on Eco-invent database from resource harvesting to recycling. The study aims to assess Iran's energy production/consumption portfolio, but technical construction, operation, and recycling are not discussed. The study focuses on energy demand and energy generation resources in Iran, under three energy portfolio scenarios: (1) a basic scenario is a real energy portfolio for Iran's 2018-power demand, (2) Iran's 2050-energy portfolio with maximum accessible renewable energy capacity, and (3) Iran's 2050-energy portfolio with zero-carbon emission to evaluate the final consequences of life cycle. The York model is used to estimate energy demand in 2050. The Green-X model is used to evaluate the relationship between the impacts and economic growth. Iran's energy portfolio has a low emission, compared with the global portfolio with a 36%-coal application. Among Iran's portfolios, the most adventitious scenario is in 2018, followed by the 2050 portfolio with population growth and 50% increase in energy demand, and the zero-carbon scenario with 64% of energy portfolio based on solar and wind energy technologies. Compared with the 2018 scenario, in the second and third scenarios, the environmental effects are decreased by 40% and 52%, respectively, indicating the significance of renewable energy in reducing the environmental consequences.

“…Also, the study mentioned that the CC method minimized the financial indicators of the optimal solution more than other strategies. Some other relevant studies of the technoeconomic feasibility of HES have focused on three major groups, comparison procedures [27], design and planning [28][29][30], and energy management [31,32]. The project lifetime in all of these research articles has been set at 20 or 25 years, with no consideration of the impacts of reducing the project's lifetime.…”

Sustainable generation is impacted by the adoption of renewable energy, the growth of energy markets, and economic strategies. This paper offers a sustainable strategy and a technoeconomic analysis of off-grid hybrid energy systems (HES) in remote islands of Iran, including Lavan, Larak, and Failaka, utilizing PV module, wind turbine, and hydrokinetic turbines. Hourly wind speed, solar irradiation, and hydrovelocity have been implemented under load following (LF) and cycle charging (CC) dispatch strategies in order to ascertain the most appropriate systems. Lavan Island achieves the winning HES with a CC dispatch strategy, which consists of 3 hydroelectric turbines, 1 wind turbine, 349 kW of solar power, 150 kW of generator power, 316 kWh of batteries, and 287 kW of the converter. This ideal HES, which generates a consistent generation profile and reasonable net present cost (NPC) and cost of energy (COE) of M0.160$ and $0.013 kWh, respectively, can be practically attained in these areas. LF-controlled optimal solutions use less fuel than CC-based ones, leading to a higher share of renewable energy. Compared to Larak and Lavan, the CC- and LF-controlled options on Failaka Island generate cleaner electricity with emissions that are 57% and 44% lower. Regarding the ability to recoup the project’s initial investment costs, long-term energy production would be more financially viable than short-term. Short-term projects with higher financial uncertainty due to the salvage cost should use the CC method.
