Simplification of energy storage mathematical models is common to reduce the order of the equivalent ECM circuits, or to completely idealize them both with and without taking into account the SOC dependence.
One of the approaches in modeling ESSs is to reproduce them with an ideal voltage source Vdc and a detailed VSC ( Fig. 10 ). Fig. 10. Ideal DC link model of the ESS. In this model, the energy storage is reproduced by a DC voltage in accordance with the output characteristics of the particular energy storage unit.
Average model of the ESS. In this model, the whole power converter interface of the energy storage unit is replaced by ideal voltage sources, which reproduce the averaged behavior of the VSC legs during the switching interval.
Energy storage complicates such a modeling approach. Improving the representation of the balance of the system can have major effects in capturing energy-storage costs and benefits. Given its physical characteristics and the range of services that it can provide, energy storage raises unique modeling challenges.
In such cases, the detailed reproduction of the processes in the energy storage is usually not investigated, and the modeling tasks are to study the dynamic response of the complex energy storage model in emergency modes, including studies of the frequency and voltage support in the ECM by means of the ESS.
Reduced-order Model of ESS: KESS and TESS are the gain and time constant of the energy storage, PESS and QESS are the output active and reactive power of the energy storage. By varying the time constant, the type of energy storage and power converter are reproduced.
