“…The derating factor from Asian Development Bank is 66 percent [33]. However, typical research in the Philippines uses a derating factor of 80 percent [34,35]. The estimated price of solar PV is $2400 per kWh in a study by the Department of Energy Philippines [36].…”

In the context of the increasing frequency and severity of disasters and associated power outages, a resilient energy system is needed to ensure smooth humanitarian operations and critical emergency responses such as preparing relief goods. The availability of electricity during the relief preparation is necessary to ensure that food items are packed efficiently and effectively. This study aims to design a resilient energy system for relief preparation. The objectives include assessing energy requirements during relief operations, determining the optimal energy system, and conducting sensitivity analysis to understand the effects concerning energy demand, component prices, and solar radiation. The sensitivity analysis reveals that the hybrid PV-diesel system is robust to varying parameters.

“…Resources include hybrid systems of solar, wind, hydro, battery, and power to hydrogen for grid and off grid applications. Nonetheless, most of these studies modeled their 100% RE system using computed estimated load [33,34] or generic load data from HOMER Pro [35]. Other grid connected case studies such as [36,37], which utilized real energy data in their model, only involved a few buildings from the selected sites.…”

Achieving 100% Renewable and Self-Sufficient Electricity in Impoverished, Rural, Northern Climates: Case Studies from Upper Michigan, USA

The development of 100% renewable electricity (RE) systems play a pivotal role in ensuring climate stability. Many municipalities blessed with wealth, an educated and progressive citizenry, and large RE resources, have already reached 100% RE generation. Impoverished municipalities in unwelcoming environments both politically and climatically (e.g., northern latitudes with long, dark winter conditions) appear to be incapable of transitioning to renewables. This study challenges that widespread assumption by conducting a detailed technical and economic analysis for three representative municipalities in the Western Upper Peninsula of Michigan. Each municipality is simulated with their own hourly electricity demand and climate profiles using an electrical supply system based on local wind, solar, hydropower, and battery storage. Sensitivities are run on all economic and technical variables. Results show that transition to 100% RE is technically feasible and economically viable. In all baseline scenarios, the 100% RE systems produced a levelized cost of electricity up to 43% less than the centralized utility rates, which are predominantly fueled by gas and coal. Current policies, however, prevent such self-sufficient systems from being deployed, which are not only detrimental to the global environment, but also aggravate the economic depression of such regions. Potential energy savings advance the prohibitive energy justice principle.

Introducción: El uso de fuentes de energía alternativas ha sido tema de gran interés a nivel mundial, tanto por beneficios ambientales como económicos. A pesar de ser un tema relativamente reciente, se han realizados varias investigaciones y proyectos al respecto. Se consideran híbridas las instalaciones que incorporan diferentes fuentes generadoras de electricidad. La finalidad es obtener el máximo aprovechamiento de los recursos energéticos para reducir la dependencia de las condiciones atmosféricas. Objetivo: El objetivo de esta investigación es desarrollar un modelo de operación de una generación hibrida con componentes solar – eólico, con la finalidad de aprovechar al máximo estas fuentes de generación de energía. Método: Se definió una topología para la conexión de los dispositivos. Para la realización de pruebas se han tomado dos prototipos, uno de generación eólica y otro de generación solar. Se realizaron mediciones del sistema híbrido y se comparó su rendimiento con los dos sistemas independientes. Resultados: Se han realizado pruebas en laboratorio para verificar el correcto funcionamiento de los equipos utilizados (regulador, inversor y baterías) y pruebas en campo para tomar mediciones reales de generación de potencia del sistema híbrido. El sistema híbrido propuesto presentó un mayor desempeño frente a los otros dos sistemas independientes. Conclusiones: En este estudio podemos concluir que el sistema híbrido cuenta con la ventaja de tener mayor independencia de las condiciones ambientales para la generación de energía. Teniendo en cuenta los resultados obtenidos en las pruebas de campo, la implementación de sistemas híbridos es adecuada en la costa atlántica.
