Dynamic Power System Modeling for the Integration of Energy Storage

In this paper, a dynamic power system model is proposed, with the aim to study the interconnection between energy storage (ES) systems such as compressed air energy storage (CAES) and power networks. All features in a power system, e.g., frequency, voltage, current, active and reactive powers, are considered in the model. Furthermore, the dynamic model enable an easy integration of ES models, making it a useful software tool to study the feasibility of ES in providing ancillary services to power networks. Case studies with the integration of CAES have been carried out, which reveal that the CAES has the potential to strength and optimize the operation of power systems, especially in terms of load balance, and frequency and voltage regulation.
