Impact study of PV penetration on Mexican MV distribution network

The increase of distributed generation (DG) is now clearly significant in many countries as in Mexico. Photovoltaic systems (PV) arc the most popular, due the flexibility and simple installation. As it is known, PS' uses electronic power converters to adapt and get the necessary features as power sour-ce. Typically, PV converters produce certain implicit harmonic distortion current level due to the power electronics components. Therefore, additional considerations must be taken into account on typical distribution networks analysis. This paper shows the main effects of PV systems in a typical mexican radial network. Cases were adapted to approach the most symbolic and relevant technical and operational aspects. Maximum PV generation and minimum load conditions are considered as main operational states. Operational technical limits are taken also into account. Electrical parameters such as ener losses, power factor (PF), voltage regulation (VR) and voltage total harmonic distortion (THD) are analyzed in this context. Impact level is estimated in function of operational technical limits and electrical parameters.
