Abstract

The integration of renewable energy is transcendental for sustainable development. This article analyses a hybrid grid-connected system composed of renewable energy technologies (photovoltaichydrokinetic), where several scenarios for energy management are proposed. They include a battery system as energy storage and a system without storage but with resale fee to grid, with the aim of determining the best economic and environmental balance. The results show that, by having a (PV-HKT-GRID) system with energy storage and no resale fee to the grid, the Net Present Cost (NPC) is increased by USD $ 132, 760 and the Cost of Energy (COE) decreases $ 0.013/kWh when compared to the grid. In addition, the same hybrid system without energy storage and no resale fee to grid, presents an energy cost savings of $ 0.043/kWh, and an additional cost of USD $ 43, 630. Finally, if a grid resale rate is included in the renewable hybrid system, then the difference is noticeable, the savings in the Cost of Energy is $ 0.073/kWh and presents a saving in the NPC of USD $ 39, 930. In all cases, CO2 emissions have been avoided.

Abstract

At present, the worldwide concern about climate changes on or planet is indisputable. One of the aspects that influences environmental problems is the generation of energy through conventional methods. Due to this, the governments all over the world, and particularly Ecuador, have opted for the implementation of renewable energy for the electricity supply. In the Ecuadorian case, for example, the government established a program called “towards a new energy matrix” and also regulations to promote the use of renewable energy sources for energy purposes. Taking into account this considerations, and the possible technical challenges that Distributed Generation (DG) could create, it is necessary to study the behavior of networks after the introduction of (DG). In this thesis, the standard IEEE 13 buses distribution feeder and a real distribution feeder were chosen in order to carry out two solutions mode which are snapshot power flow and Quasi- Static Time Series (QSTS) power flow. These networks were modeled and simulated using OpenDSS, a software used in scientific literature to analyze the impact of DG in electrical power distribution systems. For IEEE 13 buses feeder, five different scenarios were defined to evaluate technical features such as losses, voltages profiles and reversed power flow; only PV generation was considered for this network while for CENTROSUR network it was considered three case of study with five scenarios each one. The cases of study for CENTROSUR were: i) only PV, ii) PVs integrated with BESS and iii) PVs integrated with BESS and induction cookers. In order to carry out simulations for CENTROSUR network, the transformer demand profile, the storage system profile, the PV profiles and the load consumption profiles of 10 minutes of resolution was used.

Abstract

En el sector financiero de la ciudad de Cuenca, aproximadamente el 75% acostumbra a utilizar la hipoteca como garantía para conceder créditos. Las entidades utilizan esta figura para asegurarse en caso que existiere incumplimiento de la obligación por parte del Deudor. Sin embargo, no se considera el uso del fideicomiso mercantil como una opción, el mismo que puede ser estructurado para garantía de bienes inmuebles. Es por esto que el presente trabajo tiene como finalidad realizar un análisis de riesgos en el proceso del uso de la hipoteca que se maneja en la actualidad; y en un segundo paso, analizar los mismos riesgos mediante el uso del producto del fideicomiso mercantil en garantía de bienes inmuebles como una alternativa para recuperar la cartera vencida con menor riesgo y mayor agilidad. El estudio termina con un análisis comparativo de las diferentes matrices de riesgos entre ambos tipos de garantía y su porcentaje de efectividad según el tipo de garantía.
