ESSs refers to a collection of devices or equipment that can store electric energy through physical or chemical means and convert it back into electricity when required. Advances in technology and theory have resulted in the development of ESSs from a simple energy storage device to a valuable contributor to power system operations.
For example, the physical-based modelling method of mechanical energy storage systems mainly utilise theories in mechanics, thermodynamics or fluid dynamics. The mathematical equations governing components with strong correlations are amalgamated to build the model [, , ].
Due to the intermittent nature of renewable energy sources, modern power systems face great challenges across generation, network and demand side. Energy storage systems are recognised as indispensable technologies due to their energy time shift ability and diverse range of technologies, enabling them to effectively cope with these changes.
This finding underscores the need to integrate new energy storage solutions that can accurately simulate the dynamic characteristics of power electronics for such applications.
The first two determine the energy supply for activities such as load following and spinning reserve. The latter is related to the activities relying on response speed, such as transmission and distribution stability and power quality regulation. The timescale of ESSs is jointly determined by the discharge duration and response time.
