Development of a Procedure for the Predictive Control Strategy of a Chilled Water Storage System
Abstract
Thermal energy storage systems store the
thermal energy produced by the chiller plant in
periods of off-peak electrical demand or when
cheaper electricity is available. The stored thermal
energy is then withdrawn from the reservoir to satisfy
cooling load during peak demand periods. This paper
discusses the development of a simplified predictive
control strategy for a 7000 ton-hour chilled water
storage system serving a hospital. Control strategies
are developed for both on-peak and off-peak months
to minimize demand charges. By optimizing the
operation of the building air handling units (AHUs),
chilled water pumps, chiller plant and the thermal
storage system, the storage tank is better charged
while chiller run time is reduced. Both on-peak and
off-peak electrical demands are expected to be
reduced significantly.
