The Dual Control With Consideration of Security Operation and Economic Efficiency for Energy Hub

This paper proposes a dual control of energy hub considering security operation and economic efficiency which is constituted by the control of energy hub outputs and inner devices. As security operation is a significant requirement of multi-carrier energy system (MCES) with energy hubs, it is necessary for MCES to regulate the outputs of hubs which highly influence the performance. The control approach of energy hub outputs can proportionally allocate the electricity and heat outputs of energy hubs. Meanwhile, the decentralized control of energy hubs can be realized to eliminate the impact of communication on security operation by implementing the proposed method. Furthermore, in view of the characteristics of energy hub, the elements in hubs also need to be regulated to reduce energy consumption. The control of inner devices based on the improved equal incremental consumption principle can reach to the minimal loss of the energy. Numerical simulations demonstrate the effectiveness of the proposed method.
