A business model of user-side battery energy storage system (BESS) in industrial parks is established based on the policies of energy storage in China. The business model mainly consists of three parts: an operation strategy design for user-side BESS, a method for measuring electricity, and a way of profit distribution between investors and operators.
In standalone microgrids, the Battery Energy Storage System (BESS) is a popular energy storage technology. Because of renewable energy generation sources such as PV and Wind Turbine (WT), the output power of a microgrid varies greatly, which can reduce the BESS lifetime. Because the BESS has a limited lifespan and is the most expensive
