Abstract
A controller used in microgrid systems that includes a primary control module and a secondary control module. The primary control module may employ a primary consensus control to control at least one of a real power and reactive power sharing in at least one distributed generator system of a microgrid. The secondary control module may employ a secondary consensus control to maintain at least one of voltage and frequency in the microgrid to a nominal value.

A controller used in microgrid systems comprising:
- a primary control module that employs a primary consensus control including at least one hardware processor to control at least one of a real power and reactive power sharing in at least one distributed generator of a microgrid, wherein the primary consensus control exchanges reactive power information between each neighboring distributed generator in the microgrid so that said each distributed generator has a proportion of total power in the microgrid;
- and
- a secondary control module that employs a secondary consensus control to maintain at least one of voltage and frequency in the microgrid to a nominal value.
A method for controlling a microgrid system comprising:
- controlling at least one of real power and reactive power amongst distributed generators of a microgrid using a primary consensus control employing at least one hardware processor to exchange reactive power information between each neighboring distributed generator of the microgrid so that each distributed generator has a proportion of total power in the microgrid;
- and
- maintaining a nominal value of at least one of voltage and frequency in the microgrid using a secondary consensus control.
A computer program product is provided that includes a non-transitory computer readable storage medium having computer readable program code embodied therein for a method of controlling a microgrid system, the method comprising:
- controlling at least one of real power and reactive power amongst distributed generators of a microgrid using a primary consensus control employing at least one hardware processor to exchange reactive power information between each neighboring distributed generator of the microgrid so that each distributed generator has a proportion of total power in the microgrid;
- and
- maintaining a nominal value of at least one of voltage and frequency in the microgrid using a secondary consensus control.
