As fossil fuel generation is progressively replaced with intermittent and less predictable renewable energy generation to decarbonize the power system, Electrical energy storage (EES) technologies are increasingly required to address the supply-demand balance challenge over a wide range of timescales.
Various application domains are considered. Energy storage is one of the hot points of research in electrical power engineering as it is essential in power systems. It can improve power system stability, shorten energy generation environmental influence, enhance system efficiency, and also raise renewable energy source penetrations.
During the decision-making process of planning, information regarding the effect of an energy storage unit on power system reliability and economics is required before it can be introduced as a decision variable in the power system model.
The third part which is about Power system considerations for energy storage covers Integration of energy storage systems; Effect of energy storage on transient regimes in the power system; and Optimising regimes for energy storage in a power system.
There are still many challenges in the application of energy storage technology, which have been mentioned above. In this part, the challenges are classified into four main points. First, battery energy storage system as a complete electrical equipment product is not mature and not standardised yet.
Generally, large-scale EES technologies that have decoupled energy and power characteristics have lower costs for longer duration with optimized system designs ; while for shorter duration storage applications, batteries could further reduce the cost by learning-by-doing and potentially using chemistries with earth-abundant raw material.
