Integrated Demand Response Mechanism for Industrial Energy System Based on Multi-Energy Interaction

This paper explores interaction patterns for multienergy demand management and proposes an integrated demand response (IDR) mechanism for industrial integrated energy system. The incentive payment is provided not only for curtailing interruptible electric load, but also for increasing flexible heating and cooling loads. The coupling characteristics of multi-energy demands are modeled to reflect the mutual influence between the consumption behaviors for different energy sources. Besides, based on the coupling of CCHP (Combined Cooling, Heating and Power) energy outputs, the demand-supply interaction model is also proposed, which could change the electric generation by stimulating heating and cooling demands. The optimization model of IDR is then established with the objective of minimizing total dispatch cost. Simulation results show that the IDR operator, CCHP and consumers could all benefit from this mechanism. Furthermore, the impact of the incentive price on the dispatch cost is also analyzed.
