A Two-stage Design Method for Integrated Energy System based on Optimistic and Pessimistic Criterion

A two-stage planning method for the planning of integrated energy system (IES) and the Optimistic and Pessimistic criterion form the model's objective functions, which reflect the attitude of decision-maker towards uncertainty of natural gas price and electricity price. The first stage optimization of the proposed model is to obtain the capacity configuration to minimize the investment cost. The second stage is an operation problem which is to achieve the optimal operation scheme to minimize the operation cost. Then, based on the framework of the energy hub in IES, the model of energy management is well formulated to minimize the total cost (investment cost and operation cost) according to the Optimistic and Pessimistic criterion. Furthermore, the proposed model is solved by Aimms solver. Finally, a case study based on Optimistic and Pessimistic criterion is employed to examine the characteristic of the proposed model for the decision-maker.
