El Centre de Recerca Motion Control and Industrial Applications (MCIA-UPC) de la Universitat Polit\u00e8cnica de Catalunya – BarcelonaTech (UPC) participa en el projecte OPTIMA, que t\u00e9 com a objectiu el disseny i desenvolupament d\u2019un sistema fotovoltaic bifacial complet, caracteritzat per la seva alta efici\u00e8ncia i per la seva adaptabilitat per a la instal\u00b7laci\u00f3 en cobertes planes d\u2019edificis d\u2019alt consum energ\u00e8tic, com s\u00f3n les d\u2019infraestructures comercials o industrials.<\/h4>

En un context marcat per la necessitat urgent de reduir el consum energ\u00e8tic i avan\u00e7ar cap a models m\u00e9s sostenibles, especialment en entorns comercials i industrials, el projecte OPTIMA neix com una resposta tecnol\u00f2gica d\u2019alt impacte, no nom\u00e9s orientada a millorar l\u2019efici\u00e8ncia energ\u00e8tica de sistemes fotovoltaics, sin\u00f3 tamb\u00e9 de fer-los adaptables i intel\u00b7ligents per maximitzar l\u2019autoconsum i reduir la depend\u00e8ncia de fonts energ\u00e8tiques no renovables.

En aquest marc, l\u2019objectiu del projecte OPTIMA \u00e9s desenvolupar diversos sistemes que, treballant de manera conjunta, aprofitin de la manera m\u00e9s eficient possible l\u2019energia solar rebuda, aplicada a l\u2019autoconsum en edificis. Es tracta d\u2019un projecte de demostraci\u00f3 que integra diferents tecnologies fotovoltaiques, mec\u00e0niques, electr\u00f2niques i computacionals, aix\u00ed com la seva aplicaci\u00f3 intel\u00b7ligent en edificacions, per demostrar que \u00e9s possible una generaci\u00f3 energ\u00e8tica neta i eficient, fins i tot en grans nuclis urbans fortament contaminats. Com a resultat del projecte, s\u2019han desenvolupat diferents prototips dels diferents m\u00f2duls del sistema fotovoltaic.

Per exemple, respecte al panell fotovoltaic, el prototip proposat presenta la particularitat de captar energia per ambdues cares (bifacial), amb capacitat d\u2019auto-orientaci\u00f3 per seguir la traject\u00f2ria del sol, mitjan\u00e7ant un sistema electromec\u00e0nic que es pot ajustar din\u00e0micament a les ombres que es produeixen sobre la mateixa coberta per tal de maximitzar l\u2019energia total capturada per ambdues cares. Per altra banda, el projecte inclou el desenvolupament d\u2019un prototip d\u2019estaci\u00f3 meteorol\u00f2gica de baix cost, que aporti informaci\u00f3 per al control del seguiment solar en temps real. Respecte a la tecnologia de gesti\u00f3 d\u2019energia fotovoltaica, el grup MCIA ha desenvolupat un prototip d\u2019inversor amb tecnologia de semiconductors de darrera generaci\u00f3 (SiC), caracteritzats per la seva alta efici\u00e8ncia energ\u00e8tica, que en combinaci\u00f3 amb un sistema propi de sensors i comunicacions permet l\u2019\u00fas d\u2019algoritmes de c\u00e0lcul de seguiment optimitzats, que milloren el rendiment energ\u00e8tic del conjunt, alhora que monitoritzen el seu estat de salut per prevenir el funcionament en condicions no \u00f2ptimes i, per tant, menys eficients.

Impacte<\/h4>

Aquest sistema presenta avantatges competitius respecte a les instal\u00b7lacions fotovoltaiques convencionals sobre coberta. En destaca una major producci\u00f3 d\u2019energia el\u00e8ctrica per unitat de pot\u00e8ncia instal\u00b7lada (kWh\/kWp) i per unitat de superf\u00edcie (kWh\/m\u00b2), fet que permet maximitzar l\u2019\u00fas de les cobertes disponibles.

Tamb\u00e9 ofereix un millor acoblament entre les hores de generaci\u00f3 i les de consum, reduint aix\u00ed la depend\u00e8ncia de la xarxa el\u00e8ctrica i la necessitat de contractar pot\u00e8ncia addicional. A m\u00e9s, s\u2019aconsegueix una efici\u00e8ncia superior en la conversi\u00f3 d\u2019energia CC\/CA gr\u00e0cies a l\u2019\u00fas de dispositius electr\u00f2nics Wide Band Gap (WBG) de darrera generaci\u00f3, amb un impacte directe en l\u2019augment de la producci\u00f3.

En la darrera fase del projecte, el Centre de Recerca MCIA ha implementat millores significatives en l\u2019electr\u00f2nica de pot\u00e8ncia, utilitzant transistors d\u2019alt rendiment de carbur de silici (SiC), que gr\u00e0cies a la seva redu\u00efda conductivitat t\u00e8rmica, han perm\u00e8s assolir una efici\u00e8ncia energ\u00e8tica del 96% Paral\u00b7lelament, el centre ha desenvolupat una interf\u00edcie de comunicaci\u00f3 Modbus TCP-IP, que habilita la connexi\u00f3 amb la xarxa i la transmissi\u00f3 de dades al n\u00favol, promovent solucions de monitoratge i la gesti\u00f3 intel\u00b7ligent del sistema en temps real.

Socis, pressupost i finan\u00e7ament<\/h4>

El projecte, amb una durada de 36 mesos (de setembre de 2022 a agost de 2025) i un pressupost total de 798.294 \u20ac, est\u00e0 coordinat per l\u2019Instituto de Sistemas Fotovoltaicos de Concentraci\u00f3n (ISFOC), societat constitu\u00efda dins del Grup Institut de Finances de Castella-La Manxa, l\u00edder en tecnologies solars, i tamb\u00e9 hi participa la Fundaci\u00f3 Eurecat.
