Zusammenfassung: | In this paper, an equivalent linearized electrical circuit of a photovoltaic generator is developed appropriate for association with electromagnetic transient packages for power systems studies which are based on nodal analysis. The proposed technique is based on published and well-tested i pv -v pv equations which are used in an alternative mathematical manner. The application of Newton-Raphson algorithm on i pv -v pv equations leads to uncoupling of the i pv and v pv quantities in each time step of a digital simulation. This is represented by a current source in parallel with a conductance. The proposed equivalent circuit is a powerful tool for power engineers who are involved in PV systems modeling since one can develop a PV generator element in electromagnetic transient programs for PV power systems studies. |
