Free QuoteAbstract: 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.
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.
Motivated by, a three-layered architecture for automatic voltage regulation (AVR) application is proposed for PV inverters to keep voltages within the specified limits in the LV distribution grid.
This paper proposes a coordinated control strategy for PV inverters in the LV grid with the aim of bringing voltages within the specified limits. The proposed method has a three-layer hierarchical structure. The AVR app at the top layer is the main component that manages reactive power outputs of PV inverters efficiently.
