Frequency and voltage regulation in droop-based microgrids is generally modeled using small-signal analysis. In order to ensure accuracy, existing models do not decouple real and reactive power responses. However, the models become complicated and hide the real decoupled dynamics. This paper proposes a simple linear model which makes it possible to discern the different dynamic properties and to readily...
Droop method is an advantageous technique for generating the grid in stand-alone AC supply systems with distributed generation. Regarding the AC voltage regulation, an interesting approach is to control the RMS voltage instead of its instantaneous value. However, this regulation has serious drawbacks when feeding non-linear loads since the voltage THD increases and current harmonics are not equally...
