Integration of heterogeneous industrial consumers to provide regulating power to the smart grid

In this paper, we propose a framework to utilize the flexibility of consumers in the future smart grid with a high share of fluctuating power. The focus is on industrial cases, where a total power consumption of a few number of consumers are large enough in order to bid in the market. Heterogeneous consumers, namely, supermarket refrigeration system and chiller with ice storage have been studied. Two common control approaches which are direct control and indirect control have been formulated. We have simulated different scenarios to compare these approaches for a heterogeneous portfolio of the flexible demands.
