Techniques and mechanisms for determining constraints to be imposed on resource utilization by customers of an electric utility. In an embodiment, flexibility metrics are determined each for a different respective customer, the flexibility metrics each indicating a respective difference between a metric of resource utilization, and a respective constraint which is imposed on that resource utilization. The customers are ranked, relative to one another, based on the flexibility metrics, where the ranking is used as a basis for selecting one or more customers to accommodate a change to a power delivery service of the electric utility. In another embodiment, one or more updated utilization constraints are imposed each by a respective customer of one or more selected customers.

A method is disclosed for controlling a charge transfer of an electric vehicle using an electric vehicle charging station, a mobile device, and a cloud server. The method includes receiving, at a mobile device, a message for an electric vehicle of a user directly from the electric vehicle charging station, wherein a user of the mobile device is associated with the electric vehicle to be charged. The method also includes receiving the charging control signal from the cloud server via the mobile device at the electric vehicle charging station in response to authorizing a charging control signal using identification information and credit account information received from the mobile device, wherein the charging control signal is configured to adjust a parameter used to draw electric power from the electric vehicle charging station.

A system and method for stirring molten material such as glass are provided. To prevent sagging of a cover of a stirring system, a portion where deformation or sagging may significantly occur is suspended by a suspension system, so that local sagging and deformation of the cover is suppressed. As a result, a crack which may occur in the cover is suppressed, and therefore, contamination of the molten material is likewise suppressed.

A method and system of configuring wind turbines is provided. The method and system includes generation of a plurality of configuration profiles. Thereafter, one of the configuration profiles is set as the active configuration profile and the rest of them are stored as shadow configuration profiles. Further, the performance of the active configuration profile and the shadow configuration profiles are monitored. Based on the performance of the configuration profiles, a candidate configuration profile is chosen. Further, a delta configuration profile is generated by eliminating the duplicate parameters from the candidate configuration profile and the active configuration profile. Further, the active configuration profile is updated with the delta configuration profile.
