Abstract

The lack of new generation capacity and the higher fuel generation cost are the serious problems of Taipower. Taipower attempted to make the optimal economic fuel-cost dispatch of its existing generation capacity by applying direct load control method (DLC). However, some constraints such as the outdoor temperature, thermal comfort level of consumers, and air-conditioning load payback phenomenon restrain the executions of DLC. In order to alleviate the above problems, a reasonable DLC program with a least enthalpy estimator (LEE)-based fuzzy thermal comfort controller of air-conditioning systems is proposed in this paper. It can store the heat transfer capacity of the chilled water by a time delay after load-shedding command is issued. With the help of the proposed LEE-based fuzzy control and this pre-stored chilled-water heat transfer capacity, a smaller increase of the chilled-water temperature during off-shift period is obtained which can avoid the transient payback load effect. Meanwhile, the thermal comfort is also maintained within an acceptable level.
