With the development of energy storage technology and decrease of energy storage cost
energy storage has become an important means of load control. The economic benefits of energy storage allocation in power demand side are evaluated. Firstly
the cost calculation model considering the whole life cycle is established. Secondly
the benefit calculation model is established from four aspects of grid side
user side
power side and policy subsidy.Finally
it is concluded that this energy storage can obtain good economic benefits through example analysis. In addition
it is concluded through sensitivity analysis that factors such as energy storage cost
peak-valley price difference and policy subsidy have a great impact on the economy of energy storage system.
