Integration of energy storage systems is economically justified if the costs of energy storage systems do not exceed the costs of energy from the market. The economic top-down approach in Ref. [ 18 ] shows how energy storage costs depend on the user''s economic environment, an annual number of storage cycles, and on storage …
