Abstract
A power system controller using a 2×2 decoupling controller, a model reference, and feedback with delay. Embodiments provide control of microgrid frequency F and voltage V. In addition, this technique can also be used to control the real and reactive power delivered from the microgrid to the connected macrogrid. The control engineering approach is the same in both cases, but the roles of the four variables involved are reversed.
