System and method for power load management
First Claim
1. A power load management system for regulating the energy demand from a distribution panel comprising a load control switch for selectively decoupling specific loads from a distribution panel in response to a demand limiting signal, the load control switch also providing load feedback data;
- and a control unit for monitoring the load feedback data and operational parameters for providing the demand limiting signal in accordance with a power management algorithm;
the operational parameters including at least one of;
a user weighting factor, a utility weighting factor, a power source limit, a utility limit, a total system load and a rate limit factor.

Abstract
A power load management system for regulating power demand from a distribution panel of a residence or building is disclosed. Load control switches placed in-line between circuit breakers of the distribution panel and the loads they control, such as a water heater, pump, AC unit etc., provide load feedback data to a load management CPU. The load management CPU monitors the load feedback data and other operational parameters for selectively switching load control switches to the open circuit state to ensure that the total load demanded does not exceed the demand limits imposed by the power source. The load management CPU includes adaptive algorithms to automatically prioritize loads based on user and utility applied weighting factors, and patterns of loading based on time and date.
