Dynamic Modeling and Flexibility Analysis of an Integrated Electrical and Thermal Energy System With the Heat Pump–Thermal Storage

The integration of high-efficiency heat pump and thermal storage devices is great significance to realize the synergy between efficient flexible operation integrated electric energy systems. This article proposed an electric–thermal system with introduced current method for constructing its overall dynamic power flow model by considering transfer, conversion, processes. On this basis, we derived constraint component equations. Under objective wind curtailment minimization, comprehensive effects characteristics pump, capacity, new installation, load on output are analyzed. results show that dispatching accuracy can be improved up 8% taking into account pump. combination device in a leverage factor 3.06 0.17 release processes, respectively, effectively increasing flexibility scheduling. coordination newly added installation load, higher operating temperature more conducive promote accommodation improve system’s flexibility. These provide necessary basis development dispatch plan systems containing pump–thermal storage.
