In response to the problem of limited and inefficient random production simulation methods considering energy storage in renewable energy power systems,based on the reliability evaluation of power generation systems,a comparative analysis of existing research on energy storage participating in random production simulation methods was proposed.A new method of energy storage participating in random production simulation was put forward,which involved charging and discharging energy storage,keeping the demand curve unchanged,and continuously correcting the technical output and climbing speed of the system.The impact of energy storage participation in random production simulation on energy storage charging and discharging expectations and system reliability evaluation through reliability testing system(reliability test system,RBTS)simulation was simulated and analyzed.The results indicate that the proposed new method of energy storage participating in stochastic production simulation has significant accuracy and efficiency.Therefore,the new approach can flexibly respond to changes in power generation capacity,bringing new solutions for the stable operation of power systems containing energy storage.
