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.
In addition, the voltage fluctuation and power quality issues may limit the PV penetration level and hence mitigation measures are needed to alleviate the potential problems. In this paper, the impact of PV on the distribution network in term of voltage performance and losses has been investigated by using the OpenDss simulator tool.

If the frequency is <50 Hz, the solar plant shall continue injecting active power until the frequency reduces below 47.5 Hz. b. For over-frequency between 50 and 50.2 Hz, the solar power plant shall maintain the 100% of active power. Table 2. Range of voltage at the PCC.
Furthermore, voltage fluctuation, flicker, harmonics, unbalanced power flow, and line overloading are among the emerging challenges related to the large-scale integration of PV generation in the distribution networks.
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.
