In the quantitative evaluation of the absorption capacity of multi energy regional power grids,the current methods cannot reflect the real-time consumption of the power grid in time,resulting in errors between the evaluation results and the actual results.A quantitative evaluation method of multi energy regional power grid absorption capacity based on time series state is proposed.Taking the annual maximum energy consumption of the power grid as the goal and constraining the operation of the power grid,a simulation model of the time series state of the power grid is established,the energy curtailment index value and economic index value of the multi energy regional power grid are estimated according to the simulated time series state,and the weighting method is used to calculate the consumption index of the multi energy regional power grid,so as to complete the quantitative evaluation of the consumption capacity of the multi energy regional power grid based on the time series state.The results show that the mean absolute error of the quantitative evaluation method of multi energy regional power grid absorption capacity based on time series state is within 0.1 and root mean square error is within 1%,and the evaluation results are more accurate.
