The microgrid is an environment constructed with the aim of controlling local distributed resources. The most common power flow control technique utilised inside a power electronics dominated or standalone microgrid is - a technique known as power frequency droop. This paper develops a novel droop controller based on an arctan power profile that can provide natural limiting of frequency deviations and accurate frequency output. The new control system has been simulated in SABER and results are presented that show the advantages of the control. A low voltage microgrid consisting of two inverters and a passive load has been constructed. Experimental results from the hardware system are presented to confirm the operation of the new droop controller.
