The energy arbitrage is defined as purchasing the energy at off-peak times by low prices, storing in the ESS, and selling it by high prices at peak times to achieve financial benefits, and the main base of energy arbitrage is price differences during periods of a day (Ikeda & Ooka, 2016; Mohd et al., 2008).The revenue of an ESS facility depends on the application of it.
