Implementasi Metode Derivative Cluster Area Methods (Dcam) Untuk Meningkatkan Daya Keluaran Pv Dengan Tegangan Keluaran Konverter 12 Vdc
ABSTRACT
PV power plants, also known as photovoltaic power plants, convert solar radiation energy into electrical energy through the photovoltaic effect. However, current methods of extracting energy from PV power plants have not yet achieved optimal efficiency. This research aimed to determine the optimal power output of a PV system using the DCAM method and a buck converter, with a fixed output voltage of 12V and a connected load. The DCAM method is an algorithm for obtaining the highest possible power output from a PV system by calculating the area under the PV V-I curve. In this study, the DCAM method was implemented in the PV system by adjusting the load to achieve optimal power output. Changes in the output load affected the duty cycle of the buck converter. The results of testing the DCAM method showed an average power increase of 14% compared to traditional power search methods. The DCAM method produced a power output of 9.57 W under solar radiation of 800 W/m2, while traditional methods produced 8.13 W. The results of testing the PV system showed a difference between the output power and the DCAM reference power of 77%-90%, while simulation results showed a difference of 15%-30%. The implementation of the DCAM algorithm, based on integration, in determining reference power for the buck converter control system offers a new method for optimizing PV power plants.
