“…Although hybrid systems provide a promising alternative to single source energy system, the sizing of individual energy system and limited operational experience increases the design complexity. Various probabilistic and deterministic approaches have been used to develop models of hybrid systems to find optimum combination of the available resources and assess the system's performance [3][4][5][6]. This work evaluates the techno-economic feasibility of a hybrid system generating power for a small community using wind turbine and PV along with grid connection to further ensure uninterrupted power flow.…”

This work investigates the feasibility of hybrid power generation system using multiple energy sources to fulfil the electrical demand of a residential community. The system performance is evaluated against the capital investment, Cost of Electricity (COE), CO2 emissions and Net Present Cost. Results indicate that the hybrid system reduces the COE by 47% compared to grid price and has a negative CO2 emissions of 24,603 kg/yr due to supplying its surplus energy to the grid. Renewable sources contribute to 80.1% of the overall power produced by the hybrid system. The study finds that the hybrid systems could replace complete dependency on grids.

“…The Power Conversion Efficiency (PCE) was too low (in the order of 0.1% or lower) and it could not be increased for more than 20 years (Holger et al 2004). In 1986, Tang developed bilayer hetero junction OSCs with a PCE of about 1% which is regarded as a major milestone for OSC (Tang C. et al 1986;Prodhan et al 2017;Cheyns et al 2010;You J. et al 2013).…”

Enhancement of light absorption in solar cell presents a strong challenge to its overall performance. We analyzed an Organic Solar Cell (OSC) with Photonic Crystal (PC) structure using Finite Difference Time Domain (FDTD) method. Aluminum oxide (Al2O3) has been used as photonic crystal structure and the lattice structure has been chosen to be hexagonal. Absorption enhancement has been observed by changing the height of the Hexagonal Lattice structure (HLS). When height is increased to 0.26 and radius to period ratio (r/a ratio) is set to 0.4, there is a significant increase of absorption in the middle wavelength region approximately from 463 nm to 575 nm and a significant decrease in lower wavelength. As the height is increased further, these changes in absorption begins to increase and at a certain value, these changes begin to reverse. Almost same phenomena occur when r/a ratio is 0.2 and 0.3 taken at approximately same height.

“…Esta combinación puede aumentar la eficiencia de los sistemas frente a una única tecnología, proporcionando un mayor equilibrio en el suministro de energía y contrarrestando las variaciones en los recursos energéticos. Además, suelen mejorar los factores de carga y ahorrar costes de O& M (Bala & Siddique, 2009;Prodhan et al, 2017).…”

Energy access allows to improve population life quality, specifically in terms of food, education and health. Currently, 10% of the world population does not have electricity. 85% of this population is mainly concentrated in rural areas of developing countries. In order to increase electricity access, the national interconnected grid can be extended or, also, isolated systems can be implemented. In particular, systems based on the use of renewable energies are an appropriate option for the most remote communities, since they reduce dependencies on external resources and fossil fuels. Rural electrification planning consists in defining the strategies to be used to satisfy the energy needs of the population without electricity, regarding the design of projects, prioritizing and ordering their execution in time. In many countries, different rural electrification plans have been implemented at a regional and local scale, but they have not always been successful mainly because of the standardization in the design of systems, instead of the detailed analysis of the specific requirements of each population. In this context, this doctoral thesis aims to analyse rural electrification plans and develop a planning proposal at regional scale, which considers the particularities of each community, in the design of projects and their prioritization. In a region of a developing country with several communities without electricity, this proposal would be the guide for electrification promoters throughout the whole decision-making process to select the most appropriate electrification system to be implemented in each community and prioritizing the communities to be electrified, considering technical and social aspects. For the definition of an appropriate planning proposal, it is necessary to consider the key aspects that condition and/or guarantee the sustainability of projects. Hence, this work carries out an evaluation of different rural electrification project plans that have already been implemented, in order to identify and extract the lessons learned and, thus, consider them in the implementation of future plans. Based on the results of the evaluation, the planning proposal is defined, which consists in 3 stages. In stage 1, the initial evaluations are carried out to compile the information (socioeconomic, energy and technical) at regional scale. In stage 2, a definition of projects is performed, where different electrification technologies are compared for each community. Finally, in stage 3, the prioritization of projects is realized, where a hierarchical order of communities is sought from where to start the implementation, considering technical and social criteria. The planning proposal is validated through its application to a real case study, called the Solar communities network (RECOMSOL), which covers 8 rural communities in Chiapas (Mexico) and is promoted by the Chiapas University of Sciences and Arts (UNICACH). Thus, the proposal is demonstrated adequate to implement rural electrification plans at a regional and local scale in developing countries, since it allows the promoters to guide and interact throughout the whole decision process in a clear and systematized way, obtaining results validated by the promoters of the systems. El acceso a la energía permite mejorar la calidad de vida de las personas, específicamente en la alimentación, la educación y la salud. Actualmente, el 10% de la población mundial no tiene electricidad. El 85% de esta población, se concentra principalmente en zonas rurales de países en vías de desarrollo. Para aumentar el acceso a la electricidad, se puede extender la red interconectada nacional o, también, implementar sistemas aislados. En concreto, los sistemas basados en el uso de energías renovables son una opción adecuada para las comunidades más remotas, ya que disminuyen la dependencia de recursos externos y combustibles fósiles. La planificación de la electrificación rural consiste en definir las estrategias a utilizar para satisfacer las necesidades energéticas de la población sin electricidad, en cuanto al diseño de proyectos, priorizar y ordenar su ejecución en el tiempo. En muchos países se han implementado diferentes planes de electrificación rural a escala regional y local, pero no siempre han resultado exitosos debido principalmente a la estandarización en el diseño de los sistemas, en vez del análisis detallado de los requerimientos específicos de cada población. En este contexto, esta tesis doctoral tiene el objetivo de analizar planes de electrificación rural y desarrollar una propuesta de planificación a escala regional, que considere las particularidades de cada comunidad, en el diseño de proyectos y en su priorización. En una región de un país en desarrollo con varias comunidades sin electricidad, esta propuesta sería la guía para los promotores de la electrificación en todo el proceso de toma de decisiones para seleccionar el sistema de electrificación más adecuado a implementar en cada comunidad y priorizando las comunidades a electrificar, considerando aspectos técnicos y sociales. Para definir la propuesta de planificación adecuada, es necesario considerar los aspectos clave que condicionan y/o garantizan la sostenibilidad de los proyectos. Así, este trabajo realiza una evaluación de diferentes planes de proyectos de electrificación rural que ya han sido implementados, con el propósito de identificar y extraer las lecciones aprendidas y, así, considerarlas en la implementación de futuros planes. A partir de los resultados de la evaluación, se define la propuesta de planificación, que consta de 3 etapas. En la etapa 1, se realizan las evaluaciones iniciales para recopilar la información (socioeconómica, energética y técnica) a escala regional. En la etapa 2, se procede con una definición de proyectos, donde se comparan distintas tecnologías de electrificación para cada comunidad. Por último, en la etapa 3, se realiza la priorización de proyectos, donde se busca un orden jerarquizado de comunidades por dónde empezar la implementación, considerando criterios técnicos y sociales. La propuesta de planificación se valida mediante su aplicación a un caso de estudio real, denominado Red de comunidades solares de Chiapas (RECOMSOL), que cubre a 8 comunidades rurales de Chiapas (México) y que está impulsado por la Universidad de Ciencias y Artes de Chiapas (UNICACH). Así, se demuestra que la propuesta de planificación es adecuada para implementar planes de electrificación rural a escala regional y local en países en desarrollo, ya que permite guiar e interactuar a los promotores en todo el proceso de decisión de forma clara y sistematizada, obteniendo resultados validados por los propios promotores de los sistemas.
