Abstract: Systems, methods, and computer program products for organizing messages received through different channels and from multiple sources. In response to receiving a message at a user system from a first communication channel, the user is prompted to identify a bucket to which the message should be added. In response to receiving input identifying the bucket, the message is stored and indexed to the identified bucket. Messages are thereby organized so that messages pertaining to the same matter are indexed to the same bucket. In cases where a query is received from a message application requesting instructions for processing the message, the user system transmits a reply to the message application instructing the message application to forward the message to a network address where the message is received from a second communication channel different than the first communication channel.

Abstract: A distributed synchronization method for interconnecting a microgrid with adjacent power grids at multiple points of interconnections. Receiving a request to connect to the microgrid from a first identified adjacent power grid. Synchronization controllers for each generator of the microgrid identify the generator connecting to the point of common coupling between the microgrid and the first adjacent power grid, and assigns the generator as a leader generator. Determining a frequency synchronization correction and a voltage synchronization correction by the synchronization controller of the leader generator, from synchronization parameters received from the first adjacent power grid. Adjusting active and reactive outputs of the follower generators and the leader generator and connecting the first adjacent power grid with the microgrid when a set of predetermined thresholds are satisfied.

Abstract: A power system including a first grid and a second grid, each grid having power flow parameters. A breaker installed at a point of common coupling between the first grid and second grid. A first sensor and a second sensor, each located on a side of the point of the common coupling for continually determining the power flow parameters of the first grid and second grid. Wherein the power flow parameters for the first and second grid are indicative of a frequency and a phase. A power source for supplying power to either the first grid or second grid. A controller for synchronizing the frequencies and the phases of the first and second grid, by continually adjusting an amount of power supplied, based on continually determining a frequency mismatch and a phase mismatch between the first grid and second grid, until a first predetermined condition is met.

Abstract: A power conversion system including a power source configured to provide input power is disclosed. The power conversion system also includes a first power converter comprising switches configured to convert the input power to an intermediate converted power. The power conversion system further includes a controller configured to control the switches based on an asymmetrical voltage cancellation mode wherein the controller is configured to operate the first power converter at a fixed operating frequency, maintain a zero voltage switching mode and control a duty cycle of the switches. The power conversion system also includes a contactless power transfer system configured to transmit the intermediate converted power to a load wherein the load is coupled to a second power converter that converts the intermediate converted power to an output power wherein an output voltage of the output power is controlled by the controller based on the asymmetrical voltage cancellation mode.
