ANALYSIS OF POWER SHARING BASED ON SMALL SIGNAL STABILITY IN A DC MICROGRID A

Control techniques are wildly used and popular method to improve operational performance of microgrid. Control techniques are divided into two groups: centralized and decentralized that also known as droops controlled. In this paper, droop based decentralized control of a microgrid is studied for power sharing. In order to analysis stability, state space equation is derived. Dynamic model of each component is extracted individually and used for microgrid stability analysis. Eigen values of system indicate that variation of PI controller results in changing the location of system poles. Results show that system stability depends on system and PI controller parameters.
