Why are energy storage systems used in electric power systems?

Part i☆ Energy storage systems are increasingly used as part of electric power systems to solve various problems of power supply reliability. With increasing power of the energy storage systems and the share of their use in electric power systems, their influence on operation modes and transient processes becomes significant.

Does energy storage complicate a modeling approach?

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.

Are energy storage systems a key element of future energy systems?

At the present time, energy storage systems (ESS) are becoming more and more widespread as part of electric power systems (EPS). Extensive capabilities of ESS make them one of the key elements of future energy systems [1, 2].

Can ESS models be used to simulate real power system dynamics?

However, there is no review in the literature of the detailed mathematical models of common ESS technologies that can be used for simulation and comprehensive analysis of real power system dynamics. The article consists of two parts.

What is a technologically complex energy storage system (ESS)?

Also, technologically complex ESSs are thermochemical and thermal storage systems. They have a multifactorial and stage-by-stage process of energy production and accumulation, high cost and little prospect for widespread integration in EPS in the near future [, , ].

Why is chronology important in energy-storage modeling?

The importance of capturing chronology can raise challenges in energy-storage modeling. Some models ‘decouple’ individual operating periods from one another, allowing for natural decomposition and rendering the models relatively computationally tractable. Energy storage complicates such a modeling approach.
