“…Ali, Shafiullah and Urmee [70] determined that a PV/diesel/battery hybrid system is the most economical and environmentally friendly solution for the Hulhumalé Island. What is more, regarding specific evaluations of the Galapagos Islands, in reference [71], the optimization of the Baltra-Santa Cruz power system was In 2018, this system generated 35 GWh and the RE share was only 18% [15]. The RE generation represents a saving of approximately 2.6 million liters/year and a reduction of 5150 tons of CO 2 emissions [51].…”

The fragile ecosystem of the Galapagos Islands is being affected by population growth, intensive tourism, the exploitation of local resources and the high consumption of imported fossil fuels. This unsustainable development model makes the provision of services such as electricity a challenge. This research investigates the hybrid renewable mini-grid Baltra-Santa Cruz, which represents 62% of the electricity generation mix of the archipelago. This study aims to support the Galapagos Zero Fossil Fuel Initiative and the Sustainable Development Goal 7 through the reduction in diesel consumption and electricity generation costs. To do so, HOMER Pro, a specialized hybrid renewable mini-grid planning tool, is used to perform several techno-economic assessments, focusing on different electricity demand scenarios. Therefore, multiple pathways are compared to identify the most reliable alternatives towards the progressive decarbonization of this hybrid system. The results indicate that installing 18.25 MWp of photovoltaic and 20.68 MWh of battery capacity could reduce the Levelized Cost of Electricity (LCOE) from 32.06 to 18.95 USc/kWh, increasing the renewable energy (RE) share from 18% to 39%. Additionally, the successful application of energy efficiency measures would even reduce the LCOE to 17.10 USc/kWh. What is more, distributed energy is considered the most attractive way to involve islanders in the energy transition process. Finally, this paper offers a comprehensive business model proposal to achieve a resilient energy supply, based on a combination of auctions and energy community models, which demands high political will, reliable and innovative regulations and social awareness about energy use.Sustainability 2020, 12, 2282 4 of 47 and implement RE projects. In addition, the Ecuadorian Electricity Master Plan (PME) 2016-2025 [44] contains the list of priority projects to increase renewable electricity generation. Moreover, those possible new partners can propose additional RE initiatives thanks to the General Regulation of the LOSPEE. This regulation [43] is based on the targets of the National Plan of Development 2017Development -2021 which prioritize RE resources exploitation to reduce the dependency of fossil fuels. What is more, new companies interested in developing RE projects can receive an income-tax-exemption for five years [46].As regards distributed generation, the photovoltaic microgeneration to electricity self-sufficiency for final consumers of electricity regulation [47] and its amendment [48] promote the installation of PV systems up to 300 kWp per user in the residential sector and below 1000 kWp per user in the commercial and industrial sectors. This regulation is not limited to rooftop PV systems. A net-metering scheme is applied to compensate electricity costs. Thanks to this mechanism, consumers are billed for their "net" electricity use and the associated costs become credits for the following months if the electricity balance is positive for users. [47].

“…Then, the power generation structure was analyzed. In a micro-grid case, the authors of [110] presented power generation planning considering the integration of EBs and ETs. For this purpose, the charging loads of EBs and ETs for different scenarios were modeled to obtain the optimal generation portfolio.…”

“…Some remote communities or islands located far away from a mainland depend on isolated micro-grids based on diesel fuel, which is environmentally harmful [124]. These effects are even worse if pristine and protected environments are considered [110]. Therefore, micro-grids with RES are being developed, creating concerns for micro-grid stability due to the RES generation uncertainties and fluctuations.…”

The market for electric vehicles (EVs) has grown with each year, and EVs are considered to be a proper solution for the mitigation of urban pollution. So far, not much attention has been devoted to the use of EVs for public transportation, such as taxis and buses. However, a massive introduction of electric taxis (ETs) and electric buses (EBs) could generate issues in the grid. The challenges are different from those of private EVs, as their required load is much higher and the related time constraints must be considered with much more attention. These issues have begun to be studied within the last few years. This paper presents a review of the different approaches that have been proposed by various authors, to mitigate the impact of EBs and ETs on the future smart grid. Furthermore, some projects with regard to the integration of ETs and EBs around the world are presented. Some guidelines for future works are also proposed.
