This paper presents a review of the impact of rooftop photovoltaic (PV) panels on the distribution grid. This includes how rooftop PVs affect voltage quality, power losses, and the operation of other voltage-regulating devices in the system.
Some major standards for PV integration in distribution systems such as IEC 61727, IEEE 1547, and VDE-AR-N4105 are defined and used in to ensure that the power quality and stability defined by grid codes for PV sources connected to the grid are maintained.
This means that PV participation in voltage regulation is more effective in a lower voltage grid than a medium voltage one. On the contrary, if PVs do not participate in reactive power support, the hosting capacity of medium voltage grid to PV would be higher than the low voltage one.
Although research related to the possible impacts of PVs on the distribution grid has seemingly matured, there are still areas that require further exploration. One area of research pertains to control algorithms adopted for distribution systems with high PV penetration levels.
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.
Current power systems are not designed to support the massive integration of PV and to respond to the grid codes. The application of intelligent and online control methods for better coordination between all parts of modern electrical systems is very important.
