Voltage and frequency restoration control and economical operations at decentralized and centralized secondary control are analyzed in detail. Based on the existing literature, critical discussion on MG control and future trends are also presented to provide future research perspectives.
To obtain the mitigated frequency deviation of primary control, the secondary control is developed based on the concept of adding the compensating term \ (\omega _ {s,i} (t)\) which represents the computed output derived from the secondary controller while \ (M_ {p\omega , i}\) represents the slope of frequency law’s droop.
The communication-based methods provide an accurate power sharing, fast transient response, high power quality and reduce circulating power among the inverters. However, implementation of these methods needs a high-band width communication link.
From these equations, it can be understood that the voltage difference is correspond to the active power and the power angle correspond to the reactive power. Therefore, the frequency can be controlled by reactive power flow and the voltage can be controlled through the active power, as well.
