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。
