摘要:
A system and method of determining priorities for restoration of power in a power distribution system includes collecting customer prioritization data for a set of customers. An inconvenience factor is determined from the customer prioritization data for each customer. A zone restoration factor is then determined from the inconvenience factor for each customer. The inconvenience factor takes into account the estimated outage time, the customer's back-up time, the willingness of the customer to use back-up devices, and customer's priority for the estimated outage time.

A hand weapon that appears to be an innocuous key carrying device is employed for self-defense. In a first preferred embodiment, the device includes a hollow handle having flexible cordage, typically a double cord, that passes through it to which a number of keys or other weighted objects are affixed via an attachment mechanism, usually a split-ring or similar mechanism. A spring-loaded plunger mechanism extending radially through a cross-section of the hollow handle pinches a portion of the flexible cordage in the interior of the hollow handle to hold it in position. A first position is where the attachment mechanism abuts a first end of the hollow handle. If an attacker threatens, the user depresses the spring-loaded plunger mechanism while slinging the first end with weighted objects affixed, typically keys, toward the attacker using a slashing movement. The weight of the keys aids in rapidly deploying the flexible cordage to a second position, which reaches full extension when the stop mechanism abuts the second end of the hollow handle. This action permits the keys to be hurled to and fro at an attacker. This self-defense device may be used for blocking and counterattacking the attacker.

A system and method for minimizing load shed during restoration after a fault in a power distribution network includes collecting customer prioritization data for a set of customers and calculating an inconvenience factor from the customer prioritization data on each customer in the set of customers. A load reduction required for restoration is determined, and at least one zone to be isolated from the power distribution network based the load reduction and the inconvenience factor is identified. The identified zone may then be isolated from the distribution network. The customer prioritization data may include customer priority data, customer load data, customer back-up device data, customer available back-up time, data related to willingness of customer to use their back-up device.

One embodiment of a method for optimizing utility cost comprises receiving a rating for at least one device comprising at least utility service usage information for the at least one device; receiving a desired time of use for the at least one device; receiving utility rate information comprising cost information for the utility service at various times over a defined time period; determining a total cost to use the at least one device at the desired time of use based on the utility service usage information for the at least one device and the utility rate information at the desired time of use; and determining an economical cost to use the at least one device based on the utility service usage information for the at least one device and the cost information for the utility service at various times over the defined time period.
