Abstract

A basic algorithm provides a tool to help a power user maintain power consumption below allowable demand interval peak limits as defined by the user. A central processor is connected to monitor operation and control power application to various equipments, such as might be utilized within a facility. The algorithm determines when and what equipment to turn on and off, so that proper scheduling of that equipment can be accomplished and power demand peaks reduced. Reduction of power demand peaks results in reduced power costs.

Power Management

A basic algorithm provides a tool to help a power user maintain power consumption below allowable demand interval peak limits as defined by the user. A central processor is connected to monitor operation and control power application to various equipments, such as might be utilized within a facility. The algorithm determines when and what equipment to turn on and off, so that proper scheduling of that equipment can be accomplished and power demand peaks reduced. Reduction of power demand peaks results in reduced power costs.

The algorithm requires input data to define loads and operating periods as well as priorities. Essentially seven major input data areas are required including: (1) identification of equipment which must be turned on at a specific time of day and day of year, (2) equipment that must be started and stopped at regular intervals, (3) pieces of equipment that are required to be on but are off including priorities associated with such equipment, (4) pieces of equipment that are on but can be turned off with appropriate priorities associated with these equipments, (5) the user defined power limits, (6) the power utility demand period, and (7) equipment scheduling lists containing specific information on each piece of equipment. Based on the above input data, the following equation defines the algorithm to project the breakage or exceeding of the user defined limit: Projected Limit = ((Power Not Controlled By Program) X (Time Left in...
