With the proliferation of photovoltaic systems connected to the utility grid, it is necessary to study their impact on voltage quality in the electrical network in several conditions, since they use inverters to convert DC power to AC power. In this paper, we present an experimental analysis of a 9.45 kWp grid-connected PV system installed in the rooftop of Centre de Développement des Energies Renouvelables (CDER) in Bouzareah, Algiers, Algeria. It is made of 90 modules divided into three identical sub-systems of 30 modules generating 3.18 kWp. Three single-phase inverters, of 3kWp nominal power, were used to connect the PV system to the low voltage (LV) distribution network. The Voltage behavior, the total harmonic distortion (THD), short-term (Pst) and long-term (Plt) voltage flicker indexes are measured in the common connection point (PCC) in two cases, the first one with injection of PV production and the second case without injection of PV production.

摘要

With the proliferation of photovoltaic systems connected to the utility grid, it is necessary to study their impact on voltage quality in the electrical network in several conditions, since they use inverters to convert DC power to AC power. In this paper, we present an experimental analysis of a 9.45 kWp grid-connected PV system installed in the rooftop of Centre de Développement des Energies Renouvelables (CDER) in Bouzareah, Algiers, Algeria. It is made of 90 modules divided into three identical sub-systems of 30 modules generating 3.18 kWp. Three single-phase inverters, of 3kWp nominal power, were used to connect the PV system to the low voltage (LV) distribution network. The Voltage behavior, the total harmonic distortion (THD), short-term (Pst) and long-term (Plt) voltage flicker indexes are measured in the common connection point (PCC) in two cases, the first one with injection of PV production and the second case without injection of PV production.
