User-side energy storage can not only realize energy transfer but also serve as the main part of the DR resource to reduce customers'' energy costs and the loss of load shifting/curtailment. Besides the DR, energy arbitrage, and providing reserve capacity, energy storage is also investigated for demand management in this paper.
On the user-side, the number of charging and discharging cycles of the energy storage system is limited per day, and the battery life may normally be expected to be around 10 years [18]. At the same time, because batteries account for the majority of all costs, it is reasonable to take the failure time of the second batch of batteries as the life of …
