Method and system to co-optimize utilization of demand response and energy storage resources

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.

1. A method to provide co-optimized utilization of demand response and energy storage resources in an electrical grid system, comprising:
obtaining a grid system load; estimating a dispatch cost in connection with the grid system load from energy supply cost curves stored in a database;evaluating a marginal savings relative to the dispatch cost if a demand response event is performed, wherein the evaluating of marginal savings regarding a demand response event comprises estimating at least one aggregate demand response profile for each potential group of demand response participants, wherein the evaluating of marginal savings regarding a demand response event for each potential group of demand response participants comprises
based on a respective aggregate profile of a respective demand response group being evaluated, adjusting an original load forecast; revising a dispatch cost based on the adjusted load forecast; calculating a savings in the dispatch cost relative to the original load forecast; subtracting an option or threshold cost of the demand response event from the calculated savings to determine a net savings; and selecting a demand response group with a highest normalized savings, which meets each load-reduction constraint to which the given objective may be subject; evaluating a marginal savings relative to the dispatch cost if an energy storage event is performed; determining a control strategy to perform a dispatch comprising a demand response event and/or an energy storage event, which is selected to co-optimize an integrated utilization of the demand response and energy storage resources to meet a given objective based at least in part on the respective marginal savings of the demand response event and/or the energy storage event, wherein said control strategy is further based on parameters indicative of an aggregate of hybrid operational capabilities resulting from the integrated utilization of the demand response and energy storage resources relative to the given objective; and performing a dispatch consistent with the determined control strategy.
