A PV Hosting Capacity Technique on Distribution Network with Considering New Grid Requirement

Grid-connected distributed photovoltaic systems are becoming more prevalent and their spread could pose technical hurdles to the grid in the form of voltage spikes, equipment overloads, power quality issues, and protection breaches. Grid-connected distributed photovoltaic systems might be needed to support the restoration of remote distribution feeder power during an emergency. This condition can occur due to the non-dispatchable nature of PV generation which tends to be difficult to control and fluctuates, depending on the irradiation and environmental conditions received by the PV. However, having rooftop PV in the distribution network also interferes with voltage regulation, which causes the voltage to fluctuate throughout the day based on the PV rooftop's power output and to decrease at night. The results demonstrate that, depending on the technical circumstances that arise, namely the value of reverse power, the value of voltage, short-circuit current capacity, and power factor (pf) against the limit defined grid code boundaries, can determine the maximum capacity (hosting) that the network can receive from the PV penetration of each scenario.
