This algorithm improves confidence in se by estimating parameters and states at the same time. simulation results on test power systems which range in size from 4 to 118 buses, have shown the virtues as follows : getting unbiased estimation without detecting and identifying bad data in measurements ; solving state and parameter estimation for power system with good convergence and excellent robust property ; increasing the numbers of iterations a little bit with the test systems expanded ; estimating many transformer taps simultaneously and remaining the main state estimation ; keeping the estimated relative error within + 0. 1 % and processing efficiently equality constraints and ill condition with polynomial complexity
對ieee ? 4 118節點系統和廣西主網進行的模擬結果表明： l1范數估計具有不良數據拒絕特性，當量測量中存在不良數據時，該演算法在不經檢測和辨識不良數據情況下仍是無偏估計，具有良好收斂性，所需迭代次數隨著問題規模擴大而增長極小；能夠同時估計多個變壓器抽頭，並保持狀態估計主體；在滿足可觀測性條件下，估計的相對誤差保證在0 . 1以內；能夠有效處理等式約束和病態條件，並具有多項式時間性。 -
