PV emulation by using DC programmable sources

Abstract

The paper describes fast emulation of one selected photovoltaic system. This type of emulation reduces emulation time multiple times regarding standard emulation. By speeding up emulation time it is possible to predict electricity generation in advance on a daily basis. This facilitates the evaluation and comparison of electricity generation of photovoltaic systems of diferent power and/or diferent photovoltaic (PV) modules. The emulated electrical energy of the selected photovoltaic systems will make it possible to put forward recommendations concerning the choice of the optimal photovoltaic system with regard to the climate elements of the region.
