Abstract

The paper proposes an improved Taguchi method to determine the best capacity contracts and dispatch the power output of the self-owned generating units from almost infinite combinations. To be achieved are savings of total power expenses of the consumers with self-owned generating units. Based on the different structures of power tariff in different periods and seasons, considered simultaneously are constraints on output ranges of the self-owned generating units, power factors, and fees of regulating capacity contracts, while searching the optimal capacity contracts. To verify the feasibility of the proposed method, the paper employs the practical data from an optoelectronics factory, which includes amounts of power consumption from the utilities, capacities of generating units, and load demand forecast in the months of planning period. Numerical results obtained are compared to the existing other algorithms. The simulation results reveal that about 12.95% in average of electrical power expenses per month can be saved through the proposed approach.
