Abstract: Briefly, embodiments are directed to a system, method, and article for generating a power system load model of a power system. Power grid disturbance data may be accessed. A power system simulation engine may be prepared, wherein the simulation engine may implement the power system model of the power system. A parameter subset A may be identified from a knowledge-based approach. The parameter subset B may be identified based on a special grid event type based on the power grid disturbance data. A final parameter subset may be selectively determined based on parameter subsets A and B using a decision-making approach. At least one parameter of the final parameter subset may be tuned. One or more parameters of the power system load model may be modified based on the tuning.

Abstract: Some embodiments provide a system to prioritize power delivery from a charging station to electric vehicles. The charging station may include a communication port to receive a charge request from an electric vehicle associated with a delta platform certificate. The charging station may evaluate the delta platform certificate to determine if the electric vehicle is associated with a prioritized charging category (e.g., if the vehicle is an ambulance, police care, fire truck, etc.). A constrained optimizer may allocate power to the electric vehicle, relative to other electric vehicles being charged at the charging station, based at least in part on said determination. A charge pump may then provide power to the electric vehicle in accordance with a result from the constrained optimizer.

Abstract: A fuel cell system is disclosed, which includes an anode recirculation loop including a fuel cell stack for generating power, a fuel supply device for providing a fuel to the anode recirculation loop, an air supply device for providing air to a cathode of the fuel cell stack, a voltage monitoring device for monitoring a voltage of the fuel cell stack, and an anode protection controller. The anode protection controller decreases a current drawn from the fuel cell stack by a predetermined amount whenever the voltage of the fuel cell stack drops below a predetermined voltage threshold and decreases a fuel flowrate provided to the anode recirculation loop based on the decreased current, so as to maintain a steam to carbon ratio in the anode recirculation loop above a predetermined steam to carbon ratio limit. A shutdown method for the fuel cell system are also disclosed.

Abstract: Some embodiments provide a system to protect an electric vehicle charging infrastructure. An electric vehicle charging site may receive AC power from a power grid and provide DC power to electric vehicles. The charging site may include a plurality of monitoring nodes each generating a series of current monitoring node values over time that represent a current operation of the electric vehicle charging infrastructure. A supply equipment communication controller may receive an access request from an access requestor associated with an electric vehicle, the access request being associated with a platform certificate. A secondary actor policy decision point at the charging site may evaluate the access requestor's identity and respond with an action message allowing high-level communication with the access requestor to proceed. Note that information associated with the current monitoring node values and/or the access request may be stored in a secure, distributed transaction ledger (e.g., an attestation blockchain).

Abstract: Temperature control system and method for a fuel cell system are disclosed. The temperature control system includes a state detector, a control selector, a normal controller and an internal model controller. The state detector determines whether the fuel cell system is in a leakage condition based on a dynamic transfer function from an air flowrate provided to the fuel cell system to a fuel cell temperature. The control selector selects to switch between the normal controller and the internal model controller based on a determined result. The normal controller is configured for controlling an air flowrate of the fuel cell system which is not in the leakage condition. The internal model controller is configured for controlling the air flowrate of the fuel cell system in the leakage condition to control the fuel cell temperature. A fuel cell system with the temperature control system is also disclosed.
