Abstract: Implementations are directed to achieving a real-time and distributed control solution that can at least selectively achieve a deterministic flow of power at a virtual point of interconnection (vPOI) of a virtual microgrid, where there is limited or no power measurement data available at the vPOI. Some of those implementations are directed to automatically generating virtual microgrids for a power network, optionally including generating additional and/or alternative virtual microgrids in response to transient and/or persistent changes to the power network. Some of those implementations are additionally or alternatively directed to dynamic control of a virtual microgrid to achieve the deterministic flow of power at the vPOI thereof.

Abstract: Systems and method are described herein for determining scheduling of electrical power system loads and generation resources. A load scheduling module determines load scheduling characteristics of the electrical power system loads and the generation resources based on power system constraints including power system flow, voltage constraints associated with each electrical system loads or each generation resource, or energy storage capacity of an energy storage device coupled to at least one of the electrical power system loads or the generation resources. The load scheduling module initiates a first signal that curtails power of a subset of the electrical power system loads based on the load scheduling characteristics. The load scheduling module initiates a second signal that adjusts power of at least a portion of remaining loads of the electrical power system loads to accommodate for the subset of the plurality of the electrical power system loads having curtailed power.

Abstract: A power flow schedule of a cluster is determined by calculating sensitivity of the net power exchange bounds. Each cluster includes a different section of the power system. The cluster provides to another cluster the power flow schedule and the net power exchange bounds for determination of a second power flow schedule by another cluster based on collective net power exchange bounds, a forecast power supply of the plurality of clusters, and a forecast power demand schedule. The clusters are hierarchically arranged such that the another cluster is higher in a hierarchy than the cluster. The cluster receives from the another cluster the second power flow schedule. The first power flow schedule is adjusted locally within the cluster based on the second power schedule and the net power exchange bounds of the cluster. The power output of the cluster is controlled using the adjusted first power flow schedule.

Abstract: Systems and methods are described herein for maintaining stability of a power grid by providing a continuous power system data stream. Power system data including one or more data packets is monitored to identify reliability of data transmission. A predicted data packet is continually generated, characterizing predicted power system data of the power grid based on filtering of the one or more past and most recent non-missing and reliable data packets. A substitution factor of the one or more data packets is determined. The predicted data packet is selectively substituted in place of the one or more data packets based on the substitution factor.

For each electrical component, a deviation of the electrical component is identified based on comparison of the determined electrical characteristic value with a reference value of the electrical characteristic of the electrical component or based on identifying the deviation by means of a filtered rate of change. An alert of the deviation is provided for further characterization of an abnormality in the power system.

The error data stream and the reference data stream are processed to generate the control data stream. The control data stream is continuously output to enable control and/or monitoring of the power flow of at least one distributed energy resource.
