Adjustable robust state estimation of integrated electricity-heat system in Antarctica based on environment-adaptive dynamic projection statistics
The integrated electricity-heat energy system(IEHS) in Antarctica region has long been confronted with the challenges of abnormal data and measurement uncertainties caused by extremely harsh weather conditions,so traditional state estimation methods exhibit inherent limitations in terms of adaptability and robustness. To this end,an environment-adaptive dynamic projection statistics(EADPS) is proposed,based on which,a robust state estimation framework suitable for Antarctica environment is constructed. Based on the historical meteorological data of the Antarctic Qinling Station,the threshold for identifying outliers is optimized through a dynamic α-quantile adjustment mechanism,achieving an adaptive response to fluctuations in extreme environmental parameters and enhancing the stability of state estimation and the accuracy of anomaly identification. Taking the IEHS with a 14-node power distribution network and a 6-node heat network as an exam-ple,the simulative results show that,under medium and high severity weather conditions,EADPS significant-ly improves the estimation performance. In the high severity weather scenario,the root mean square error of power grid voltage amplitude is reduced by 26.7%,and the abnormal identification rate is increased by 24 percentage points,which can provide reliable data support for the stable operation of energy system in Antarctica.
