摘要:
Method and system to provide co-optimized utilization of demand response and energy storage resources in an electrical grid system. The system may include a module to evaluate a marginal savings relative to a dispatch cost, if a demand response event is performed. The system may further include a module to evaluate a marginal savings relative to the dispatch cost, if an energy storage event is performed, and a controller including circuitry may be configured to determine a control strategy to perform a dispatch including a demand response event and/or an energy storage event, based at least in part on the respective marginal savings of the demand response event and/or the energy storage event, which may be selected to co-optimize an integrated utilization of the demand response and energy storage resources to meet a given objective.

摘要:
A method and system for controlling demand events in a utility network with multiple customer sites. 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 method includes receiving at least one event parameter for a demand response event and identifying a pool of customers. The pool of customers includes a plurality of customers potentially usable to support the demand response event. Characteristics of each customer in the pool of customers are retrieved and a plurality of groups of customers are created from the pool of customers based on the retrieved characteristics and the at least one event parameter.
摘要:
A system and method for receiving demand response data and for grouping customers into customer groups based on the demand response data. One or more of the customer groups is scheduled for a demand response event based on the demand response data and forecast data. The selected customer groups are notified and the demand response is implemented for the selected customer groups.

A power forecasting module determines a load forecast of a distribution system (DS) and a power generation forecast of distributed energy resources (DERs) A demand response (DR) module estimates an available DR based on the load and the power generation forecast and modifies the load forecast by dispatching an optimal DR. An energy storage commitment module determines a charging/discharging schedule of energy storage devices in the system based on the modified load profile and generates a second load profile by incorporating the charging/discharging schedule of energy storage devices. An unit commitment (UC) module determines a DER schedule of supplying electrical power to the loads in the second load profile based on a first objective function. An economic dispatch (ED) module determines an optimum operating point for each DER and an Integrated Volt-VAR Control (IVVC) module controls distribution assets to maintain a voltage profile in the system.
摘要:
A method and system for controlling load in a utility distribution network are provided that initiates a shed event for a node in the distribution network by selecting premisess associated with the node that are participating in a demand response program to reduce the load at the node to desired levels. More specifically, the system and method provide for selecting only enough participating premisess associated with the node that are necessary to reduce the load to desired levels.
摘要:
A method of load dispatch generates a load dispatch curve in response to both the opportunity cost of dispatching resources with a contractually limited number of dispatches in a given time period and estimated rebound effect data. The method identifies a best time period for dispatch based on the load dispatch curve and also supply curve data and generates a resultant load dispatch schedule. The resultant load dispatch schedule is transmitted to one or more smart home meters to dispatch loads in a manner that provides the greatest economic benefit.
