Industrial conveying loads have large capacities and strong flexibility, it makes them high-quality load resources for demand response. In order to incentivize the conveying loads in demand response, an approach to aggregate the conveying loads as a cluster and an optimal control method for this cluster to participate in customer directrix load induced demand response are proposed. Firstly, an overall framework and evaluation method for clusters of industrial conveying loads to participate in customer baseline load induced demand response are proposed. The operation feasible domains of a conveying section and the conveying load cluster are constructed, respectively. Secondly, a day-ahead optimal model of conveying load clusters participating in customer directrix load induced demand response is formed, and an intraday coordination control method of belt conveyors is further proposed. Finally, a cement clinker conveying system is taken as a study case for algorithm verification. Three scenarios for the conveying load cluster system participating in customer baseline load induced demand response are compared and analyzed. The results show that the third scenario achieves the best performance; it minimizes the net cost of the conveying load cluster while driving its load shape to track the customer baseline load through simultaneous responses to customer directrix load and time of use tariff.
