For this purpose, this study utilizes measured PV power output data with a two-second resolution. Next, the voltage fluctuation mitigation potential of three different solutions is tested, namely: (i) active power curtailment, (ii) grid reinforcement and (iii) supercapacitors.
A PV penetration of 40% will already cause problematic voltage fluctuations in the considered low voltage grid. A numerical comparison among three different regulation strategies for mitigating rapid voltage fluctuations. Grid reinforcement, active power curtailment and supercapacitors reduce the magnitude of voltage fluctuations.
The power output of PV sources fluctuates due to changes in weather conditions, rain fall, and movement of clouds. The primary reason for this fluctuation is cloud movement. Given below are some of the issues of PV output power fluctuation caused by cloud movement as reported by investigators:
Mitigating methods for fluctuations in photovoltaic (PV) power can be compared. Energy storage devices such as batteries, capacitors, or SMES are suitable candidates for addressing this issue. Rapid changes in PV output power may induce unwanted voltage or frequency fluctuation at the point of interconnection.
