    Abstract:

    Demand response (DR) has played an important role in promoting the integration distribution generations (DG) into the park integrated energy system (PIES). However, the uncertainty of DGs becomes a huge challenge to the economic operation of PIES.In view of this, a PIES economic dispatch model is proposed on the basis of the information gap decision theory (IGDT).First of all, with the objective function of minimizing the operating cost of the PIES, an economic dispatch model of PIES with DR is constructed with the consideration of cooling/heating/electricity.On this basis, the IGDT is utilized to deal with the uncertainties of DR and DG. Since the traditional IGDT is only suitable for single-factor deviation coefficients, different weights are set to DR and DG to take all the uncertainties into account when analyzing the impact of economic operations of PIES.For different types of decision makers, a risk aversion robustness model and a risk seeker opportuneness model were established to meet the needs of different types of decision-making. Then, according to the GAMS software, the equivalent deviation coefficients are calculated for the uncertainties corresponding to the two different decision-making models, with the consideration of different operating cost targets. Finally, the validity of the proposed model is verified by a case study, which provides a quantitative decision-making basis for the planner to make PIES scheduling plans.
