Analysis of energy storage power station investment and benefit

In order to promote the deployment of large-scale energy storage power stations in the power grid, the paper analyzes the economics of energy storage power stations from three aspects of business operation mode, investment costs and economic benefits, and establishes the economic benefit model of multiple profit modes of demand-side response, peak-to-valley price difference and auxiliary peak shaving service. Finally the paper have analyzed and verified the model in the power grid of a province in North China as an example.
