In order to realize optimal scheduling between photovoltaic generation and electric demand at county level,this paper proposes an interval predictive scheduling optimization method for coordinating batteries and photovoltaic generators.There are three decision variables to be planned in this method,which correspond to power generation schedu-ling,charge/discharge(C/D)power scheduling,and state of charge(SOC)scheduling,respectively,and the accurate range of optimal scheduling can be obtained for any power demand predicted in the interval.This method obtains the exact range of optimal generation power scheduling and optimal C/D power scheduling by analyzing the sign positive and nega-tive characteristics of uncertain renewable parameters using Jacobian matrix.The simulation results show that the optimal SOC scheduling range of this method is larger than that of Monte Carlo method.Our proposal can provide decision analysis for optimal scheduling of batteries and photovoltaic generators at county level.
