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.
Many efforts have been made to define patterns, predict, and forecast energy use. However, changes in energy consumption may be studied in detail using various methodologies. This work presents a statistical methodology to assess changes in a facility consumption profile. Consumption patterns are obtained from a historical database of a predefined time interval, according to the type of day (day of the week, working or non-working), and an index that assesses change in the electrical consumption profile is proposed. Assessing these changes enables associating these values with possible events in a facility, which can serve to generate alarms in an energy management system, and reduce costs and maintenance periods. Additionally, a multi-criteria interpretation of the applied test table is presented that offers explanations and identifies possible causes of anomalous consumption.
The submitted paper deals with the shopping mall project that will be supplied with solar power. The selected location was "La Playa Store" shopping center located in the city of Azogues, south of Ecuador. This type of building has at least two characteristics worth studying i) the available surface on the roof, ii) the characteristics of the energy demand curve. This evaluation process establishes the energy requirement of the installation; that is, the energy potential available depending on the surface of its roof, to design a solar plant according to international standards and local ARCONEL 003/18 regulations. The tools used for the involving simulation were the Lumion software, an IFC file created and imported into the Solarius Pv energy simulator, a software specialized in the design of photovoltaic systems. The designed photovoltaic system has a projected annual energy generation of 9,3695.26 kWh; an installed price per watt of $1.1 with viable results at the end of the fifth year of implementation with an IRR of 7.33% and NPV of $390.51. As this is a commercial facility, a constant and flat consumption throughout the day is expected, so implementing solar energy would reduce the actual power requirements by 32.63%
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
