Complex Coordination Control with Entire Power Limitation and Partial Temperature Priority of Building-Multi Air-conditioning Facilities for Real-Time Pricing

Real-time pricing is one of the primary features of demand response schemes for the future smart grids. From the demand side's point of view, coordination of load management conforming to the rapid power price changes is necessary. This study attempts to optimize a number of multi-unit-type air-conditioning facilities installed in an office building by using a complex evaluation function, which consists of power cost, room temperature comfort terms with priority, and total power consumption. Since an actual experiment lacks reproducibility, simulation experiments with different electricity pricing patterns are carried out. An original air-conditioner emulating model is developed and used to conduct the simulation experiments.
