Techno-economic analysis for a photovoltaic system with Lithium-Ion battery energy storage for a residential house in Valencia-Spain

This thesis deals with a techno economic analysis of a hybrid photovoltaic(PV)-battery energy storage (BES) system. A first view is taken on the technologies and prices of the main components need, inverter, photovoltaic panels and batteries, and the possible configuration of the plant. Before proceeding with the complete analysis simulating an entire year, a comparison between an analysis made with measures based on 5 seconds time step, with the data taken in a residential hours and a PV plant in Valencia over a week, and on 15 minutes time step is done. The will is to prove the reliability of the latter one, which is way faster and lighter. Proved its reliability, an analysis over an entire year with a time step of 15 minutes is carried out to evaluate the economic profitability of a hybrid PV-BES plant. With the results it will be possible to see that, even if a plant with batteries has a positive Net Present Value (NPV), a system with PV panels only is more convenient.
