Highlights. •. Energy storage value increases with tighter carbon dioxide (CO 2) emissions limits. •. The marginal value of storage declines as storage penetration increases. •. Large-scale deployment of available battery technologies requires cost reductions. •. Energy storage increases utilization of the cheapest low-CO 2 resources.
The consumption of renewable energy is driving the development of energy storage technology. Shared energy storage (SES) is proposed to solve the problem of low energy storage penetration rate and high energy storage cost. Therefore, it is necessary to study the profit distribution and scheduling optimization of SES. This study proposes a SES
In this circumstance, ESSs attached to REG can lease the short-term use rights of idle energy storage resources to different types of REG users in different regions. Moreover, several REG users
During the five-year period, the downstream link has the highest profit margin of main business and the most stable value-added capacity. Energy storage
This paper proposes a novel energy storage price arbitrage algorithm combining supervised learning with dynamic programming. The proposed approach uses a neural network to directly predicts the opportunity cost at different energy storage state-of-charge levels, and then input the predicted opportunity cost into a model-based arbitrage control

In bids for a project by Xcel Energy in Colorado, the median price for energy storage and wind was $21/MWh and for storage and solar $36/MWh [6]. This is comparable to $18.10/MWh and $29.50/MWh, respectively, for wind and solar without storage but is still far from the $4.80/MWh median price for natural gas [ 6 ].
