Methodology to assess the influence of PV systems as a distributed generation technology

This paper shows a simplified methodology for assess the impacts of photovoltaic systems connected to a supply of low voltage distribution power system, analyzing voltage variations outside the limits according to the NTC 1340, the chargeability and losses through a development software implemented in DIgSILENT®. The development includes the characterization of solar resource and ambient temperature to estimate the generation of the photovoltaic system, with this procedure it can find an optimum rate of penetration PV on the electric network under two scenarios: first, a circuit located for residential loads and second, a commercial circuit, both in the city of Bogotá, Colombia.
