An Integrated Energy System Operation Model Considering New Electricity Marketing Strategy

Abstract

In recent years, the economic operation of Integrated Energy System (IES) has been widely concerned. How to determine the energy price has become an urgent problem to be solved of IES. In order to overcome this problem, a modified IES operation model considering new electricity marketing strategy is proposed. In this model, the combined stochastic/robust optimization (S/RO) is established to minimize the sum of electricity exchange cost, fuel purchasing cost, operating cost, flexibility adjustment cost and renewable curtailment cost. Based on the bounded uncertainty-based robust optimization (BURO), the modified IES operation model is transformed into a mixed integer linear programming (MILP) model, which is solved by CPLEX solver. The feasibility and effectiveness of the proposed model are illustrated on the IEEE 33-node distribution system with 11-node heat-cold system.
