Direct load control-A profit-based load management using linearprogramming

摘要

Conventional cost-based load management ignores the rate structurenoffered to customers. The resulting cost savings may cause revenue loss.nIn a deregulated power industry where utilities absorb the ultimatenconsequence of their decision making, reexamination of load managementnmust be conducted. In this paper, profit-based load management isnintroduced to examine generic direct load control scheduling. Based uponnthe cost/market price function, the approach aims to increase the profitnof utilities. Instead of determining the amount of energy to be deferrednor to be paid back, the algorithm controls the number of groups powerncustomer/load type to maximize the profit. In addition to the advantagenof better physical feel on how the control devices should operate, thenlinear programming algorithm provides a relatively inexpensive andnpowerful approach to the scheduling problem
