Abstract: Energy storage planning was established to consider its life of service and avoid overoptimistic planning results. The energy storage life was built on its depth of discharge and calculated by the number of equivalent discharge cycles. The storage planning jointly addressing siting and sizing embeds both unit commitment and the storage life model. Operational uncertainty impacts planning and storage life, therefore the planning employs a two-stage robust optimization. Finally, a column and constraint generation decomposition combined with dual theory was employed, for which the construction of both feasibility and optimality cuts was laid out. In a 6-node system, storage planning results of models with and without considering energy storage life were compared. Effects of factors like operational uncertainty and storage unit cost on the planning as well as the storage life in a fixed planning scenario were analyzed. Due to the high cost of storage, these factors have a greater impact on storage planning rather than the storage cycle life.
