IRR measures the return on investment for energy storage projects and represents the average annual rate of return, resulting in a net present value of zero. . Based on the internal rate of return of investment, considering the various nancial details uses particle swarm optimization algorithm based on hybridization and Gaussian mutation to get the energy storage capacity that maximizes the internal rate of return of the investment. The definition is simple, but the IRR is generally impossible to calculate without a computer. However, the variability and uncertainty of large-scale renewable energy power stations pose a series of severe challenges to the power. .
