    Abstract: A data compression/decompression methodology and system stores in a compression-side dictionary the data that has been transmitted and additionally applies to such data in the compression-side dictionary a status of being “invalid” for purposes of use as a reference in data compression until an acknowledgement signal has been received from the decompression side indicating that such data has been received. Once the compression side has received the acknowledgement signal indicating that the data in the form of a compressed data packet has been received on the decompression side, the status is changed from being “invalid” into being “valid”, i.e., into being usable as reference data for use in compressing further data elements in the data stream. Each data packet includes a stream index which is representative of the memory location in the compression-side dictionary where the first data element of the uncompressed data set of the data packet is stored.

    Abstract: A system and method for calculating real-time carbon emissions at a distribution substation level and at an individual device level is disclosed. A substation controller is provided at the utility substation that is in operable communication with one or more devices via a demand response protocol, the demand response protocol including demand response signals transferrable from the substation controller to the one or more devices and demand response signals transferrable from the one or more devices to the substation controller. A carbon emissions calculator module is embedded in the substation controller and/or the devices that is programmed to identify or receive power consumption data from respective devices and calculate carbon emissions for the respective devices based on the power consumption data. Carbon emissions data may be provided to the substation controller to provide for a determination and output of the calculated carbon emissions for each of the one more devices.

    Abstract: An electrical system can include a diagnostic device that generates a first test signal. The electrical system can also include multiple energy transfer links coupled to the diagnostic device, where the first test signals flows through a first subset of the energy transfer links. The electrical system can further include a first monitoring device coupled to the first subset of energy transfer links, where the first monitoring device receives the first test signal from the diagnostic device through the first subset of the energy transfer links. The electrical system can also include a first electrical device coupled to the first monitoring device. The first monitoring device can implement a first test procedure based on the first test signal, where the first test procedure helps determine a first condition of the first electrical device.
