Real-Time Demand Response Through Aggregate Electric

Abstract: Demand response (DR) has shown to be a promising tool for balancing generation and demand in the future power grid, specifically with high penetration of variable renewable generation, such as wind. This paper evaluates thermostat setpoint control of aggregate electric water heaters (EWHs) for load shifting, and providing desired balancing reserve for the utility.

Estimating Water Demand under Increasing-Block Tariffs

The price specification suggested by Nordin (1976) for theanalysis of demand under block tariffs is applied to estimatewater demand functions using aggregate data from the Northwest ofSpain. The traditional way of using Nordin's specification whenonly aggregate data are available (using values of marginal priceand difference faced by the average user) is compared with thetheoretically correct
