Abstract

To further exploit system flexibility resources,an optimal scheduling model for integrated energy systems （IES） is proposed,which incorporates both thermal dynamics of heating networks and user thermal comfort.Firstly,a thermal dynamic model of heating networks is developed based on the thermal energy transfer characteristics of pipelines. Secondly,the predicted mean vote （PMV） index is introduced to quantify thermal comfort,and the thermal load is determined according to the range of user thermal comfort.Then,considering the impact of heat medium flow rate uncertainty on system scheduling,the information gap decision theory （IGDT） is employed for analysis,and a robust stochastic optimization model is constructed using a risk-averse strategy.Results show that the proposed model significantly improves economic performance and enhances wind power accommodation;while the IGDT method effectively characterizes the robustness of system scheduling against heat medium flow rate fluctuations.
