PASSIVE PEAK REDUCTION SYSTEMS AND METHODS

摘要

The systems and methods disclosed herein relate to management of peak electrical demand as registered by an electrical utility meter of an electrical utility customer. The metered demand level of the customer may be monitored over a first portion of a demand charge measuring period, then a cumulative amount of energy consumed by the customer in the first portion and a projected total energy consumed during the demand charge measuring period may be calculated. Next, an offset energy amount may be determined that is the amount required to bring a net amount of energy consumed by the customer during the demand charge measuring period to lie within a target value range for the demand charge measuring period. A power source such as a battery may then be controlled to provide the offset energy amount to the customer over a second portion of the demand charge measuring period.

主权项

1. A computer-implemented method of managing peak electricity demand registered by an electrical utility meter of an electrical utility customer, the method comprising:
monitoring a metered demand level of an electrical utility customer over a first portion of a demand charge measuring period, the demand charge measuring period having a start time and an end time; calculating a cumulative first amount of energy consumed by the customer in the first portion and a projected total amount of energy consumed by the customer in the demand charge measuring period based on the metered demand level during the first portion; determining an offset energy amount required to bring a net amount of energy consumed by the customer during the demand charge measuring period to lie within a target value range for the demand charge measuring period, the net amount being a difference between a cumulative final amount of energy consumed and the offset energy amount; controlling a power source to provide the offset energy amount to the customer over a second portion of the demand charge measuring period.
