“…In recent years, problems such as environmental pollution and air quality, which are closely related to the extensive use of fossil fuels, have become increasingly relevant (Gandhi & Gupta, 2021). Therefore, to proactively address these challenges, steps must be taken to diversify the energy matrix and transform it into one with lower emissions.…”

“…A microgrid is small-scale, independent and decentralized, uses advanced energy technologies, including gas turbines, wind power, solar power, fuel cells, energy storage devices, etc., and is close to users. For large grids, a microgrid can be considered a controllable power supply unit that can operate in seconds to meet the needs of the external transmission and distribution network (Gandhi & Gupta, 2021). Table 1 summarizes the characteristics of the different DERs, their advantages and disadvantages.…”

The integration of renewable energy technologies and the consequent reduction in investment costs has led to an increase in the use of distributed energy resources (DER), which has allowed the deployment of more and more microgrids. Despite the many benefits that can be derived from microgrids, they still face many barriers to participating in the electricity industry compared to traditional grids. This paper proposes to address the implications of installing renewable energy in the parish 5 de Agosto, Stone Mine Sector of the city of Esmeraldas, through a technical-economic analysis of the implementation of a microgrid using the HOMER network software. The analysis shows that implementing a microgrid for renewable energy production significantly reduces total costs, unit energy costs and carbon dioxide emissions over the entire project life cycle. Finally, it is concluded that the photovoltaic matrix produces 82.3%, wind turbines 15.3% and the contribution from the grid is 2.45% of the total energy, respectively. The percentage of renewable energies in the system is 100%.

“…The last-mile connectivity problem remains a challenge for the developing countries [1][2]. Though the existing microgrids (MGs) are unable to provide cheaper electricity than the grid supply, the highest reliability and quality drives the growth of microgrids in developing countries [3][4][5][6]. But the poor planning strategy resulted in failure of the MGs within short span.…”

The energy efficient microgrid (MG) plays a vital role in electrifying the remote community. But the over/under sized MG resulted in high-cost or unreliable electricity. So, the optimal sizing of MG is implemented in this paper by identifying the optimal control strategy for the highly reliable solar PV/Battery/Diesel generator-based configuration. The negative impact of temperature on the performance of PV array is included in optimal sizing and the resulted changes in the capacity of MG components are estimated and presented. Also, the uncertainty of the design parameters is included in optimal sizing through the probabilistic approach and the distribution of optimal sizes for each MG components are presented to identify the size which provides highest reliability for sensitive applications. It is proved that additional 11% PV array capacity is required to compensate the power loss due to temperature effect but with the advantage of reduction in battery and converter size.

Micro-grids have become the building block of modern energy systems, where distributed resources are the characterizing feature. The charging operation of electric vehicles can be exploited as a flexible load to achieve operational goals of the micro-grid. In the particular case of car-sharing fleets, the degrees of freedom in the charging procedures are reduced when compared to private users. In this work, we illustrate how a car sharing fleet can be incorporated as a flexible load in the micro-grid management system. A linear optimization problem is formulated, where the cost function makes a trade-off between the gain in flexibility in the micro-grid and the loss incurred by the car-sharing service for delaying the recharging procedure of the EV. The proposed approach is evaluated on a data set of charging events generated by a real car-sharing fleet showing that the EMS allows reducing the daily peak demand requested to the public grid and diminishes the operational costs.
