Abstract
Compared with frequency droop control, angle droop control avoids frequency deviation, but it is hard to share active power exactly among distributed generations (DGs). Although this defect can be solved by secondary control, frequency droop control also has a similar way to eliminate frequency deviation. In this paper, several typical operating conditions are designed to test the control effects of these two control methods, and the following conclusions are drawn: using angle droop control is able to make the frequency more stable and take shorter time to enter the steady state than frequency droop control. Finally, the conclusion is validated by analyzing the simulation results.
