Abstract
With the process of low carbon transition of energy systems, renewables, particularly wind and solar, are seeing rapid growth these years. Due to the intermittency, high shares of renewable electricity would pose pressure on energy systems balance. Traditionally, systems rely on the flexible operation of thermal plants, which might be costly. A promising approach is to design and operate energy systems in an integrated manner. This paper proposed an integrated urban energy systems planning model, combining the processes of acquiring and using energy and including multiple energy systems in a single framework. A demand response module is inserted in the model, allowing part of the power load to be shifted to another period. The model is applied to a synthetic area with three regions, and ten scenarios are studied. The results illustrate that integrated planning and demand response program are beneficial for renewable electricity accommodation.
