Multi-objective Coordinated Operation for Multi-Energy Hub Considering Heat Network Model

摘要

Energy Hub is an important part of the energy conversion supply process, which integrates multi energy forms to effectively improve energy efficiency. In order to improve the efficiency of energy utilization and also consider the cost, a multi-objective optimization model including exergy loss and operation cost is established. Due to EH and users are connected by heat network, the thermal network is modeled. A heat network model which considers the time delay and loss is established, and multiple types of thermal loads has been considered. Thus, a multi-objective coordinated operation framework for multi-EH considering thermal network model is proposed. Further, a method to solve the Pareto front and a reference method based on Nash bargain for selecting a final result is given, which can be easily solved by CPLEX. Finally, numerical studies with three EHs demonstrate the effectiveness of the proposed method.
