Energy storage system (ESS) is playing a vital role in power system operations for smoothing the intermittency of renewable energy generation and enhancing the system stability. We divide ESS technologies into five categories, mainly covering their development history, performance characteristics, and advanced materials.
This paper proposes a distributionally robust optimization method for sizing renewable generation, transmission, and energy storage in low-carbon power systems. The inexactness of empirical probability distributions constructed from historical data is considered through Wasserstein-metric-based ambiguity sets.
The electrical energy storage technologies are grouped into six categories in the light of the forms of the stored energy: potential mechanical, chemical, thermal, kinetic mechanical, electrochemical, and electric-magnetic field storage. The technologies can be also classified into two families: power storage and energy storage.
The 2022 Cost and Performance Assessment analyzes storage system at additional 24- and 100-hour durations. In September 2021, DOE launched the Long-Duration Storage Shot which aims to reduce costs by 90% in storage systems that deliver over 10 hours of duration within one decade. The analysis of longer duration storage systems supports this effort.
