Abstract: The result of DG clustering is the hybrid power system while further clustering forms the intertied hybrid power system. Interfacing of intertied hybrid power system requires an interlinking converter with a legitimate power administration and control system. In contrast to individual hybrid power system (HPS), power administration of the intertied hybrid system is more complex. Autonomous droop strategy is appropriate for the intertied hybrid system where communication links are not possible. This paper proposes a new topology for control in intertied hybrid system where two hybrid power systems are connected to each other through interlink power converter. Evaluated frequencies in different HPSs can diverse. In order to manage power flow a power management strategy with consideration characteristics of common bus, a PDC- vDC2 method is proposed, and compared with conventional droop, to realize power sharing among HPS. The practicability of the proposed power sharing method is realized in MATLAB Simulink platform.
