Abstract: A software-defined network (SDN) rule modification counter system provides counters that track all changes and edits to rules at SDN controllers and SDN switches on an SDN. The system compares counters at the SDN controller and SDN switch to determine if they match. If the counters do not match, a change has been made to the rules. With the addition of rule edit statistics the SDN controller will now have visibility that a rule modification was performed. The SDN controller then verifies that the state of the device is the same as its expected state as a secondary integrity check. Based on the rule modification notification, changes to a central rules table at the SDN controller and changes to rule settings at the SDN switch are made according to pre-programmed logic.

Abstract: One of the biggest challenges for all renewable energy sources (RES) is that they are variable power generators which will require reactive power or energy storage systems (ESS) to provide reliable power quality (ideally power factor of one) at the power grid generation side. The present invention is directed to a power packet network (PPN) for integrating wave energy converter (WEC) arrays into microgrids. Specifically, an array of WECs can be physically positioned such that the incoming regular waves will produce an output emulating an N-phase AC system such that the PPN output power is constant. ESS requirements are thereby minimized whilst maintaining grid stability with high power quality. This will enable RES integration onto a future smart grid for large-scale adoption and cost reduction while preserving high efficiency, reliability, and resiliency.
