Coordinated control of distributed energy resources in a DC micro grid is very much essential in order to meet the critical load demand. A number of control strategies including droop control, Master slave control, Local control, Adaptive control have been investigated and implemented by many researchers. However due to absence of communication link in droop control it has been extensively used in dc microgrid. However the circulating current cannot be avoided which further leads to the loss of power. In this paper an effort has been made to apply markov chain along with fokker plank solution to design the the droop control for fast response during disturbances and at the same time it will also limit the circulating current. The proposed model has been tested for a standard dc microgrid model using matlab simulink.
