In other words, when the peak-to-valley price difference increases, users can increase the configuration capacity of energy storage within a certain range to obtain more economic benefits. Energy management for lifetime extension of energy storage system in micro-grid applications. IEEE Trans Smart Grid, 4 (3) (2013), pp. 1289-1296.

Energy storage can facilitate both peak shaving and load shifting. For example, a battery energy storage system (BESS) can store energy generated throughout off-peak times and then discharge it during peak times, aiding in both peak shaving (by supplying stored energy at peak periods) and load shifting (by charging at off-peak

The advantages for the adoption of energy storage include [20]: (i) promoting the penetration of renewable energy, and assisting the deployment of distribution generators [30], [31], [36]; (ii) enhancing the reliability of grid, and making more efficient use of the network [16], [38], [34]; (iii) using storage to decrease the gap between peak
