Reactive droop

WebApr 10, 2024 · One way to get around this is to use a reactive droop compensation. The way it works depends on the vendor. Typical value for situation like this will be 5% or 0.05pu. As per IEEE a reactive compensation droop will have a positive sign, however, some vendors (ie ABB) will swap the sign to facilitate the implementation. WebMar 28, 2024 · The droop control enables the parallel connection of DGs with the feature of active and reactive powers sharing [11,12]. Droop control primarily relies on the line impedance and load characteristics. Therefore, relying only on droop control has been reported as an unreliable choice because it may lead to voltage and frequency deviations .
