Tom Key, Electric Power Research Institute. Distributed photovoltaic (PV) systems currently make an insignificant contribution to the power balance on all but a few utility distribution systems.
Since the 1980s, many researchers have tried to study the impact of photovoltaics (PVs) on the distribution grid. It has been generally believed that once PV penetration exceeds a certain limit, problems and challenges could arise affecting the operation or security of the grid. Naturally, this would limit the hosting capacity of the grid for PVs.
This paper aims to investigate the factors influencing the voltage of the distribution network caused by grid-connected distributed photovoltaic power generation in China’s energy production structure, which is increasingly relying on clean energy, particularly solar energy for photovoltaic power generation, due to its reliability and low cost.
PV output was simulated using measured data with one-minute resolution. As expected, the probability density functions shown indicate that PV causes the distribution to shift toward higher voltages, but only by a small amount. The mean point of common coupling voltages increased by less than 2 V (on a 230-V nominal base).
In this paper, we survey the publications that study the impact of rooftop PVs on the distribution system, focusing on voltage profile, system losses, power flow through the lines, and other operational and technical concerns. Historically, the impact of PVs on the distribution grid was first observed in 1977 [1, 2].
