Assessment techniques of the impact of grid-tied rooftop
The standards covering voltage level in power systems are shown in Table 4. The RMS value of the voltage is the most commonly used index for voltage variation. Grid codes in different countries have their specific voltage limits as well. Some examples are 6 ±% in Australia, ±7% in Spain, ±7.5% in Hungary, and ±6% in Korea [70].
