Currently, many researchers from industry and academic institutions are working on the study of electric vehicles, battery systems and renewable energy sources (solar, wind, geothermal, etc.). In order to carry out research on each of these technologies it is required large capital investment for equipment. Additionally, problems must be faced such as variability of environmental parameters, large space requirements, pollution (in some cases), etc. The use of software and hardware to emulate different types of actual batteries shows to be a low-cost and environmentally friendly option due to some of its features. The battery emulator system has the ability to replicate the behavior of any kind of actual battery using a virtual battery model (also known as battery electric model) and a controllable DC/DC power converter to be used in laboratory environments. Moreover, emulators are not only used for batteries, these can be used to emulate fuel cells, photovoltaic systems, wind generators, thermoelectric generator, etc. This survey aims to present the technologies to implement battery emulators based on DC/DC power converters. This survey is split up into five sections. In the first section, as an introduction, we present the advantages offered by the use of battery emulators to the scientific community and the environment. The second section presents a review about batteries (technologies, models, model parameters, etc.) and also it includes the virtual battery models, which are the main components of battery emulators based on DC/DC power converters. In the third section, we present the main DC/DC power converter types used in these systems and their operation modes. Additionally, in section 4 are presented some case studies where different topologies battery emulators based on DC/DC power converters with battery model are analyzed. These topologies are focused on their use in electric vehicles (EV).Digital Object Identifier (DOI):http://dx. first section, as an introduction, we present the advantages offered by the use of battery emulators to the scientific community and the environment.

Abstract-This project presents a solution for the design of a microgrid in Jaboneria, located in Chile considering technical and economic aspects. For the design of the microgrid, the reference time of project is 20 years and a limited budget of USD $ 250836, which is conceived as a Rural Electrification Budget. In order to produce a solution to the problem, HOMER PRO software is used. Sensitivity variables were taken into account, these include the variation of the electrical load, the state of charge of the batteries and renewable electricity generation systems. In addition other design parameters such as fuel cost, limitation residential electricity consumption, battery type, annual load profiles, fixed capital costs, etc.; were used. The cost of an Energy Management System (EMS) is not considered in the present analysis. Using HOMER, an optimal solution that combines the design parameters to find an efficient electrical energy production configuration that combines renewable energy sources (solar-wind), conventional generation (diesel) and battery power was produced, prioritizing clean energy. The optimal solution is obtained by evaluating the Net Present Value -NPC (USD $) according to each of the scenarios generated by sensitivity variables. A schematic of the system components and the corresponding load profiles are shown. Then, the information concerning renewable resources that exist in the study area and the technical-economic information of each system components was introduced. In addition, parameters of model are established. A social plan of energy-efficient consumption and citizen participation is also proposed. Finally, a simulation and analysis of the results of the scenarios generated by sensitivity variables of the system are presented. The chosen solution had the lower value of NPC and it contains the final sizing of each of the system components. This solution has to be of less value than the base budget of the project.
