Peak demand cost management through load control

Multiple infeed power distributors on the TVA system are given a choice of two demand billing options. . They may pay on the summation of the peak demands of each individual infeed; or they may pay on the coincident system peak demand plus a 3% penalty. Load diversity usually makes the coincident peak option the least expensive of the two. If the infeed demand profiles may be altered so that the summation of the peak demands of the infeeds does not exceed the coincident system peak demand by more than 3%, summing the individual infeed peak demands becomes the less expensive method. This thesis investigates the possibility of using computer controlled load shifting among infeed substations to achieve this alteration in demand profiles for the Knoxville Utilities Board system.
