Paper Title
Review of Different Droop Control Method
  Dipakkumar R. Gondalia

in transmission line, there are large quantities of distributed generators in micro-grid, which are all connected with PCC (Point of Common Coupling) through inverters. The droop control method is widely used to distribute active and reactive power among parallel inverters because its properties of low cost, high stability and no need of communication channel. In a micro-grid, the inductance values of transmission lines connecting to respective inverters are different due to the low density of distributed generators. In addition the settling time of the traditional droop control is high. In that situation, the reactive power cannot be equally shared even if all the inverters are using the same droop control method. With regards to this problem, a modification, called virtual impedance loop, is put forward for the droop control strategy to share reactive power equally in this paper. To improve the system response and settling time the arctan function also implement in power-frequency droop control strategy. The feasibility of the design is validated by simulation.

Keywords- Droop control, Virtual impedance loop, Arctan function, Reactive power sharing
