Droop-free controls of inverter-based generator for use in systems that interconnected with synchronous generators

Because of its simplicity and autonomous operation, droop control technique is widely implemented for power generation in microgrids. Despite popularity, it has been reported that the stability problem. In this paper, previous work droop-free inverter-based generator designed operating a fix frequency islanded microgrid, redesigned to have ability operate both grid connected microgrid as well main where interconnected with synchronous generators. The proposed voltage source inverters use phase locked loop(PLL) algorithm synchronize changing due operation generator. Unlike output varied active changed, controls do not make an adjustment system frequency. This kind reduces chance unstable severe change also deviation when increases output. Simulation result meshed network demonstrate feasibility implement thereal system.
