Abstract
Med stigende investeringer i nettilsluttede solcelleanlæg (PV) bliver det stadig vigtigere at sikre stabil og driftssikker teknologi. PV-invertere, som omdanner jævnstrøm fra solpaneler til netkompatibel vekselstrøm, kan overophede og tage termisk skade. En måde at forebygge dette er at anvende styring af Constant Power Generation (CPG), styret af forskellige parametre. Dette projekt sammenligner tre hovedstrategier til at implementere CPG. De vurderes i udvalgte scenarier på baggrund af energikomkostningen for hver opstilling og undersøges for, om de reducerer Lifetime Consumption (LC), dvs. hvor meget af komponenternes levetid der forbruges.
As investment in grid-connected photovoltaic (PV) systems grows, ensuring stable and reliable operation is increasingly important. PV inverters—which convert DC from solar panels into grid-compatible AC—can overheat and suffer thermal damage. One way to prevent this is to apply Constant Power Generation (CPG) control, guided by different parameters. This project compares three major strategies for implementing CPG. It evaluates them in selected scenarios based on the energy cost of each setup and examines whether they reduce Lifetime Consumption (LC), meaning how much of the components’ lifetime is used.
