Abstract: Methods and systems for an electric vehicle charging decision support system are provided. A system can include: a higher level agent configured to be connected to an energy grid and to receive a charging request from an electric vehicle and transmit the charging request to a virtual block agent; and a plurality of charging station agents connected to an energy service provider, the energy grid, and the virtual block agent. The virtual block agent can be configured to receive a respective power set-point and availability from the plurality of charging station agents and transmit a recommended energy price charged at a respective charging station to the energy service provider. The recommended price can maximize a probability of an electric vehicle agent choosing a particular charging station. The system facilitates a win-win situation for the mutual and simultaneous benefit of electric vehicles and the power grid.

Abstract: Systems and methods for detection of spoofed sensor measurements in a microgrid are provided. A system can include a control agent that is configured to determine whether an isolated or continuing intrusion of measurement data received from the primary sensors has occurred, and transmit forecasted measurement data to the controller rather than suspected corrupt measurement data for a suspected isolated intrusion. The control agent and a clone agent can be configured to communicate and work in parallel to confirm a continuing intrusion is occurring, and the control agent can be further configured to transmit measurement data from the redundant sensors to the controller if a continuing intrusion is confirmed.

Abstract: Embodiments of the present invention include methods and apparatuses for securing data transfer in power-system automation and smart grids. Embodiments of the present invention can be particularly helpful in securing GOOSE messages. A method of securing data transfer according to an embodiment of the present invention can include a message sequence synchronization and monitoring server (MSSMS) providing random seeds to a publisher intelligent electronic device (IED) and a subscriber IED, both having a pseudo random number generators (PRNGs), inputting the random seeds into the PRNG of the publisher IED and generating a publisher sequence hopping number, sending a message to the subscriber IED with the publisher sequence hopping number attached, and determining if the message is valid by comparing the message attached publisher sequence hopping number to a subscriber sequence hopping number generated by the subscriber PRNG.
