Abstract

Embodiments are directed to systems and methods for controlling the start-up sequence of two or more electrical devices. An electronic controller intercepts a plurality of initiation signals configured to start a plurality of electrical devices. The controller then implements a delay between the initiation signals so as to avoid demand spike surcharges.

Claims

1. An electronic controller including a memory module and at least one processor for controlling a start-up sequence of two or more electrical devices, wherein the electronic controller is configured to perform the following:

intercepting at the electronic controller a group of two or more externally generated initiation signals configured to initiate two or more different electrical devices;

storing the group of two or more externally generated initiation signals in the memory module in sequence as they are received;

prioritizing the sequence of initiation signals stored in the memory module such that initiation signals associated with electrical devices with higher priority are scheduled to be passed to their respective electrical devices before the initiation signals associated with lower-priority electrical devices;

determining an electricity demand value for each of the two or more different electrical devices, where the electricity demand value comprises the amount of electricity required to simultaneously initiate each of the two or more different electrical devices;

determining a usage threshold, the usage threshold specifying an electricity usage limit beyond which additional cumulative demand electricity fees will apply regardless of the time of day at which the usage threshold is exceeded, the cumulative demand electricity fees comprising fees charged for stacked spikes in electricity demand that exceed the usage threshold;

upon determining that the cumulative electricity demand values from the two or more different electrical devices is determined to be less than the usage threshold, passing initiation signals to the two or more different electrical devices based on the prioritized sequence of initiation signals;

implementing one or more delays in passing initiation signals that would cause the usage threshold to be exceeded, such that the remaining initiation signals within the prioritized sequence of initiation signals are passed to the associated electrical devices after the implemented one or more delays, wherein the implemented one or more delays are calculated, based on the electricity demand values associated with each electrical device, to be long enough to avoid surpassing the usage threshold due to multiple stacked electricity demand spikes and thereby avoid cumulative demand spike fees; and

passing the group of two or more externally generated initiation signals that do not exceed the usage threshold to the associated two or more different electrical devices without delay.

2. The electronic controller of claim 1, further comprising a delay preset module, wherein the delay preset module delays any subsequent initiation signals such that only a set number of devices are activated within a preset delay period.

3. The electronic controller of claim 2, wherein the preset delay period of the delay preset module is user-adjustable.

4. The electronic controller of claim 2, wherein the preset delay period of the delay preset module is set by the manufacturer of the electronic controller.

6. The electronic controller of claim 2, where the length of the preset delay period for a selected electrical device is set based on one or more characteristics of the selected electrical device.

7. The electronic controller of claim 1, further comprising:

an act of determining a level at which spike surcharges apply for a given user; and

based on that determination, further determining appropriate delay periods for the electrical devices such that the determined spike surcharge level is not exceeded.

8. The electronic controller of claim 1, further comprising a plurality of micro-controllers, each micro-controller comprising an input lead for receiving an initiation signal from an external initiation signal generating device, and an output lead to relay an activation signal.
