A customer-interactive electric water heater demand-side management strategy using fuzzy logic

Abstract

This paper describes a fuzzy logic-based demand-side management (DSM) strategy to shift the peaks of the average residential electric water heater power demand profile from periods of high demand for electricity to off-peak hours. The DSM strategy is achieved by dividing the distribution area water heaters into several blocks and controlling each by a different fuzzy controller. Simulation results are presented to show the effectiveness of the proposed DSM strategy to shift the average electric water heater peak demand to off-peak periods and to level utility distribution demand profile.
