Controlling virtual microgrids in a power network

A method implemented by one or more processors, comprising:

• generating, based on a graph of a power network, a virtual microgrid that includes a virtual point of interconnection (vPOI) and that includes automatically controllable resources based on the automatically controllable resources being topologically behind the vPOI;
• in response to generating the virtual microgrid:
• operating a virtual microgrid controller for the virtual microgrid, operating the virtual microgrid controller including:
• processing, using the virtual microgrid controller, power flow setpoints for the vPOI and estimated power flow measurements for the vPOI to generate control actions for achieving the power flow setpoints at the vPOI, and
• transmitting the generated control actions to one or more of the automatically controllable resources to achieve the power flow setpoints at the vPOI.

A system, comprising:

• memory storing instructions;
• one or more processors operable to execute the instructions to:
• identify current power flow setpoints for a virtual point of interconnection (vPOI) for a virtual microgrid, the virtual microgrid including the vPOI and a plurality of electrical resources topologically behind the vPOI, the plurality of electrical resources including one or more automatically controllable resources;
• generate current estimated power flow measurements for the vPOI, wherein in generating the current estimated power flow measurements one or more of the processors are to use a network model to estimate the current estimated power flow measurements and one or more of the processors do not utilize corresponding real measurements for all of the electrical resources topologically behind the vPOI;
• generate, based on processing the current power flow setpoints and the current estimated power flow measurements using an integral action feedback controller, one or more control actions to achieve the current power flow setpoints, each of the control actions being for a respective one of the automatically controllable resources;
• and
• cause transmission of the one or more control actions to one or more of the automatically controllable resources that are topologically behind the vPOI.
