Abstract
Spanish’s energy market is experiencing big changes. Renewable energy sources and decentralization of production are on the rise. An example of this is PV systems for self- consumption with or without batteries, in houses or other buildings. One clear advantage of this is the reduction of transmission losses. In addition, this type of systems will serve to reduce CO2 emissions and allow for a better implementation of electric cars in today’s society. The aim of this thesis is to analyse the solar potential of the UC3M Campus of Leganés and Campus of Colmenarejo. Installed capacity in both campus will be maximised in an attempt to achieve “full self-consumption”, defined as the point where yearly energy generated and consumption level off. System Advisor Model will be used to simulate PV generation. This term is ambiguous, as it seems that it refers to independence from the grid and 100% renewable penetration. However, it is a reflection of the PV potential of the location at hand. Spanish regulatory framework regarding the energy sector has been modified twice in the last year. The recent Royal Decree (RD 244/2019) will be explained, allowing for a better understanding of each scenario studied. Moreover, a statistical analysis of the demand and generation for both campuses will be performed, using various tools. A Matlab script has been created for this task and to store all data found, which may serve for future work regarding the university. Results showed that over 1MW of capacity was installed in Leganés, and around 10MW in Colmenarejo, which had land available for the panels. From this project, it was concluded that full self-consumption is feasible in Colmenarejo (827.63MWh) but not in Leganés (7.85GWh), as demand is larger and space limited. For a combined case, using space from both campuses to meet their total demand, full self- consumption is achieved (8.68GWh). In addition, if remuneration of excess energy (see section [1.1.2.2]) was aimed, only Colmenarejo would be an option, with a total of 11.3 MWh a year of injected energy. A 100kW system would produce no excess energy with Leganés’ consumption. This means that for every scenario but the first one mentioned, all energy injected to the grid would mean losses, with the current regulatory framework. Moreover, the use of batteries with total power capacity of 500kW in Leganés would be beneficial from an energy point of view, allowing for a reduction in injected energy of around 37MWh in the first year. For the combination of both cases, with a total power capacity of 3MWh, injections would be reduced to 1GWh annually.
