Business model and economic benefit evaluation of power grid side energy storage system

Based on the analysis of the grid side energy storage business model and operation mechanism, considering the local load and electricity price in Zhejiang, the economic analysis model of energy storage system is established. For lithium-ion battery, the economy of battery energy storage system on the grid side is calculated in detail and the sensitivity analysis of key parameters for lithium-ion battery is carried out. The simulation results show that the application of lithium-ion battery in power grid side energy storage has certain economy.
