PV-Electrolyzer plant: models and optimization procedure
No full textThe work focused on the analysis of the connection between a photovoltaic (PV) plant and an electrolyzer for hydrogen production. On the basis of PV plant and electrolyzer experimental data, the effectiveness of the models adopted in the simulation program has been verified in order to choose the best model and, eventually, modify some parameters.
By running the simulations, the procedure to optimize the PV plant and the electrolyzer combination has been established. In fact, the simulation results might be considered to size an electrolyzer as small as possible, which is able to exploit up to the maximum power actually produced by the PV plant during a working year. This criterion allows minimizing the overall plant costs. Furthermore, the possibility of deleting the Maximum Power Point Tracker (MPPT) and the DC/DC converter has been analyzed. On the basis of the obtained results, this opportunity is preferable to avoid the energy losses in the power control system; and it is convenient even from an economic point of view, considering that the electronic devices costs are comparable with the PV plant ones

Social Impact Method of Energy Analysis: improvements and results
No full textSIMEA (Social Impact Method of Energy Analysis) is a new methodology to evaluate the environmental impact of energy systems. The SIMEA approach is based on "enlarged environment" definition, considering as environment not only the natural environment, but also the "human environment", with so including the economy structure, social organisation, cultural and historical aspects of the site.
The aim of SIMEA is to consider in an integrated way many possible effects on the environment (considering the definition of enlarged environment: nature economy, culture etc) of an energy system and evaluate the social consequences and effects as social impact.
SIMEA is being developed in an "iterative" way, so after the first development end validation in 1996, a second version SIMEA has been realised and tested by applying the improved methodology to the same site. The improvements and results are proving the methodology effectiveness and show that a possible computer aided application can be expected after analysis of the comparison between the two experiences.
