Optimal Design of a Diesel-PV-Wind-Battery-Hydro Pumped POWER system with the Integration of ELECTRIC vehicles in a Colombian Community

Abstract

This article proposes a novel design methodology for hybrid isolated microgrids, integrating electric vehicles (EV) as additional loads and also as additional storage systems in the microgrid design stage. The proposed method highlights the application of electric vehicles in rural environments. Two types of electric vehicles were considered: (1) EV that only operate in charging mode; and (2) EV that can interchange power with the microgrid (V2G). For both EV types, a dispatch strategy was developed to optimize the use of the system resources during the charging process. As an application example of the proposed design methodology, a hybrid microgrid was designed for the rural Colombian village of Unguía. The results show the advantages of the inclusion of EV as ancillary services providers for the system and also as public transportation agents.

Communication and Advanced Metering Issues for the Incorporation of Renewable Energy Resources in Microgrids

“…advances in small-scale generation technologies, as well as the desire to reduce dependence on coal-based generation, have been the main drivers for the growing participation of renewable energy generation in the power grid [5]. In this context, microgrids have played a key role, since they allow the integration of distributed energy resources (DERs) which include distributed generation (DG), demand response (DR) and storage systems [6], [7].…”

Aplicación del criterio de mínimo costo en la determinación del óptimo tamaño de planta para una empresa cafetera en Antioquia

“…Lo que significa es que el analista de planta deberá considerar las expansiones frente a los costos, ya que una gran ampliación de capacidad pude incrementar los costos económicos por dos razones: primero, porque los recursos empleados para ampliar el sistema permanecerían improductivos hasta que se necesite la capacidad adicional; segundo, estos recursos no podrían aprovecharse en usos mucho más productivos en otras esferas de la economía, lo cual representa el costo de oportunidad de la ampliación. Por lo tanto, la solución óptima podría encontrarse al lograr un equilibrio entre las posibles economías de escala y los costos de oportunidad menores asociados a las inversiones de menor escala [16].…”

Optimal Operation of a Hybrid Power System as an Island Microgrid in South-Korea

“…Renewable energy can replace existing energy sources as they depend on natural energy sources that are perpetual and do not deplete. Power generated from renewable energy is primarily sourced from solar, wind, hydro, and geothermal [4][5][6][7]. Advanced countries have been developing power generation technologies that use renewable energy sources and pursue various demonstration projects to promote their spread [8][9][10].…”
