Abstract: Large solar photovoltaic (PV) penetration using inverters in low-voltage (LV) distribution networks may pose several challenges, such as reverse power flow and voltage rise situations. These challenges will eventually force grid operators to carry out grid reinforcement to ensure continued safe and reliable operations.
These challenges will eventually force grid operators to carry out grid reinforcement to ensure continued safe and reliable operations. However, smart inverters with reactive power control capability enable PV systems to support voltage quality in the distribution network better.
of smart inverters to contribute to voltage regulation. The IEEE standard is not prescriptive as to how smart inverters shall support grid voltage management, instead it requires a set of capabilities that smar
Another potential solution is the utilization of PV inverters for voltage control due to their control of active and reactive power generation capabilities . It is to be noted that power electronic converters based PV systems are able to provide reactive power support for their entire operational range.
