The project would give continuity to the Final Project of the student Ana Garre, whose exhibition was attended by the general director of Energy, Esther Marín The UPCT and the Community, through the General Directorate of Energy and Industrial and Mining, study the installation of a pilot plant at the Polytechnic of Cartagena to investigate and disseminate the benefits in terms of energy efficiency of electricity demand management systems in photovoltaic installations.
Both institutions work in an agreement that still has administrative procedures.
The plant would simulate a domestic or commercial consumption and check the disturbances in the electrical system of surpluses not consumed in homes and SMEs with photovoltaic energy generation equipment.
The project, which could have a financing of 100,000 euros by the ERDF Funds, would allow continuing lines of research such as the student of the Master's Degree in Industrial Engineering Ana Garre, whose presentation of the TFM came this week the general director of Energy and Industrial and Mining Activity, Esther Marín.
"Ana has a great scientific vocation and it would be great to have funding so that she could develop her research on electric self-consumption", explains the vice-rector of Research of the UPCT, Beatriz Miguel.
"The pilot plant would have to be located in a public place, like the UPCT, so that it also carries out sensitization functions in terms of energy efficiency," stresses Esther Marín.
The Master Final Project (TFM) of Ana Garre, directed by Antonio Gabaldón, has proven that demand management allows the percentage of self-consumed energy to be increased up to 77% by adapting the charges to solar production, thus improving the profitability of the Photovoltaic systems.
The student details in her TFM how the charges associated with the costs of the system penalizes the self-consumed energy, raising remarkably the years of amortization of the investment to install photovoltaic energy systems.
The student has measured how the use of storage systems, using batteries, increases self-consumption by 17% in a house, 22 "in an SME and 5% in a public building, but decreases the profitability of the system due to the need to replace the batteries periodically.
The student has also calculated the losses they generate when the orientation of the solar panels is not towards the south.
In particular, orientations to the north, west and east decrease their performance by 53%, 29% and 17%, respectively.
The optimal inclination of the modules has also been encrypted, which must coincide at least ten degrees with the latitude of the site.
The influence of the different tariffs on the annual cost of energy has also been verified, concluding that the most suitable for residential consumers and small and medium-sized companies is the night rate, which coincides with the period in which solar self-generation is not possible.
"It is a very meticulous and objective work," stressed the general director after attending the presentation.
"We are interested in continuing the research with the pilot plant because it is very important to raise awareness of the importance of domestic energy efficiency," he added.
