Dimensioning of energy capture, generation and storage systems, through renewable energy sources, to provide autonomy, self-sufficiency, and energy independence from the grid to a house in the Canary Islands

Abstract

This master's thesis, belonging to the university master's degree in renewable energies at the University of La Laguna, consists of the dimensioning of energy use facilities based on renewable energy sources according to the procedures of calculation fixed to normative of application, and aim to project a design of the energy installations necessary to provide a single-family home currently connected to the grid, in the Canary Islands, with the necessary self-sufficiency according to its energy demand, focusing directly into the electricity and hot water demands. The idea is that the projected systems work synergistically with each other, to offer the end user, with respect to the installations connected to the network, normal use in their home installations, as well as maintaining the same living comfort. This work also seeks greater independence of the electricity distribution and marketing system, and thus protect itself from the volatility of electricity market prices, which strongly depend on the tensions of the socio-political-economic panorama at the international level, which goes beyond of the control of the citizens. And in the other side, it also seeks demonstrate that it is possible to reach to produce in a mediumlong-term several monetary savings. That means that their cost of implementation due the required capital investment, can return because them will be amortized investments in reasonable terms, between 6 and 15 years, also guaranteeing sufficient self-consumption energy generation for self-supply of demand of the familiar core. In addition, this kind of investment also promoting some SDGs established by the 2030 Agenda, as the number 7 about clean and accessible energy for everyone, and 8, 9, 11, 12, 13, betting for the development of the ecological and energy transition. Lastly, mention that this, that so important is at a global level, can today be carried out in whole Spain as a fact, in a practical way thanks to a lot of aids and subsidies programs running on which are being promoted from the Government.
