This paper proposes a fully distributed control methodology for secondary control of AC microgrids. The control framework includes three modules: voltage regulator, reactive power regulator, and active power/frequency regulator. The voltage regulator module maintains the average voltage of the microgrid distribution line at the rated value. The reactive power regulator compares the local normal...

According to the latest developments in smart grid infrastructures of recent modern networks, in this paper, end-consumers are presented as a means for participating in networks voltage distribution control. In this regard, for reactive power control of the smart grids, a distributed control approach is proposed as an efficient approach which improves computation burden of the problem, consider...
This paper develops a new distributed secondary cooperative control scheme to coordinate distributed generators (DGs) in islanded microgrids (MGs). A finite time frequency regulation strategy containing a consensus-based distributed active power regulator is presented, which can not only guarantee the active power sharing but also enable all DGs’ frequencies to converge to the reference value w...
This paper presents a distributed hierarchical control framework to ensure reliable operation of dc microgrid (MG) clusters. In this hierarchy, primary control is used to regulate the common bus voltage inside each MG locally. An adaptive droop method is proposed for this level, which determines droop coefficients according to the state-of-charge (SOC) of batteries automatically. A small-signal...
One of the most important control methods in induction motor is direct vector control. This method is based on rotor flux estimation using stator voltage. The machine voltage is low in The voltage model for low speed and voltage drop over the stator resistance is not negligible in front of stator voltage. Thus the stator flux estimation using voltage method is not precise. Some methods are base...
