In the islanded operation of microgrids, various control strategies have been developed to guarantee stable operation of microgrids. In this paper, different power sharing methods such as droop controller, average power sharing (APS) method, and master–slave method are compared in AC and DC islanded microgrids with converter–based distributed generations (DG). The suitable controller (voltage controller and power sharing controller) for each DG is designed. Different scenarios of load variations are tested using Matlab\Simulink sofware to compare the accuracy and effectiveness of power sharing methods. Based on the simulation results, suitable power sharing method in each microgrid (AC or DC) is chosen based on its performance and minimum power sharing error.<\div>

This paper presents a decentralized controlscheme for voltage balancing and power sharing in bipolar dcmicrogrids. This relies on utilizing a converter topology whichoffers three levels of output voltage availability with the keyfeatures of boosting the input voltage and balancing the outputvoltages. This converter makes it possible to further improve thestructure of bipolar dc microgrids as it does not require a centralvoltage balancer. Small–signal analysis is done and systemtransfer functions are derived. Based on the RGA concept thehighly coupled input–output pairs are found which helps withreplacing the MIMO control system of the converter by two SISOsystems. The appropriate voltage and current controllers aredesigned based on SISO principles. Moreover, a double droopcontrol method is proposed which fulfills the simultaneous powersharing and voltage regulation of DG units in the host microgrid.The effectiveness of the proposed control strategy isdemonstrated through simulation studies conducted on anislanded bipolar dc microgrid involving unbalanced loads, whilethe voltage balancing of the bipolar dc microgrid and the powersharing accuracy are evaluated.<\div>
