摘要:
A method for demand response management includes determining (62) a number of available demand response events, and determining (64) a number of opportunities available to issue the available demand response events. A priority for each demand response event is provided (66) and a threshold value for each demand response vent is determined (68). A highest priority demand response event among the available demand response events, whose threshold value is lower than an observed value of a selected demand response trigger, is selected (70). Control signals to utilize the selected demand response event for a current opportunity are transmitted (72) to customer sites.

A protection system (72) for a power distribution system (70) includes a bus voltage sensing unit (92) to measure a bus voltage or a load voltage and a demand response module (94) for estimating available demand resources on the distribution system (70) for a period of interest. A distribution system analyzer (93) is provided in the system for analyzing the bus voltage or the load voltage and system parameters to obtain voltage trip points for the available demand resources. A load control circuit (96) controls the available demand resources based on the voltage trip points.
摘要:
A system and method for simultaneously restoring power to loads in a distribution network that experienced an outage. The pickup load on the feeder in the distribution network is estimated (412) and the load limit on the feeder is determined (414). The load on the feeder is divided into groups (416) based on the load limit. A restoration load control process is determined, and power is restored to each of the groups simultaneously based (418) on the power restoration control process.
摘要:
A system and method for use in a network of utility customers to estimate demand response for various utility DR programs. The system first aggregates the premises (104) into clusters based upon customer information for each of the premises (602,604,804). A response estimation function is developed for each of the clusters (606,706,808,906). The demand response event request is then processed according to the clusters and the response estimation functions.
摘要:
A method and system (100) for controlling demand events in a utility network with multiple customer sites (104). The value of a demand response parameter threshold for invoking a demand response event is calculated based on the number of available demand response events and the number of opportunities remaining to issue the available demand response events. This parameter represents the utility objectives for using the demand response program (e.g., cost savings, reliability, avoided costs). A current value of the demand response parameter is compared to the threshold value, and a determination is made whether or not to call a demand response event for the current opportunity, or to save the event for a future opportunity based upon this comparison.
摘要:
A system for optimal planning of electric power demand is presented. The system includes a node comprising one or more smart charging plug-in electric vehicles (SCPEVs), a processing subsystem, wherein the processing subsystem receives relevant data from one or more sources; and determines an optimized SCPEV load and optimal charging schedule for the node by applying an operations research technique on the relevant data.

A method and system (100) for controlling load (116) in a utility distribution network are provided that initiates a shed event for a node in the distribution network by selecting premisess (112) associated with the node that are participating in a demand response program to reduce the load (116) at the node to desired levels. More specifically, the system and method (100) provide for selecting only enough participating premises (112) associated with the node that are necessary to reduce the load to desired levels.
