With the rapid increase of the installed number of distributed photovoltaic and wind power systems at home and abroad, energy storage has become an important means to solve the intermittency and volatility of photovoltaic, wind power and other new energy, promote absorption, reduce wind power and solar energy waste, and thus drive the development of energy storage systems. Since there are numerous combinations of energy storage configurations and charge-discharge strategies, it is difficult to calculate with an exhaustive method. If some simple strategy estimation is carried out manually, there will be some problems of inaccurate profit estimation and low efficiency.

In order to quickly make investment decisions, we have developed an "Intelligent Energy Storage Benefit Evaluation System" for optical storage scenarios and price bid energy storage scenarios. With the input of historical load, electricity generation, electricity price and other data, the income, payback period and daily charging and discharging strategy of each energy storage configuration can be quickly calculated.
