Question

With a flat start of voltages in the following problem, and assuming the upper - triangle nonzero values of the admittance matrix to be of the following form, first find the net injected active power estimation at Bus 4, then if the total load at Bus 4 is equal to 40 pu, determine the error in estimation of the net injected active power in the first iteration. Y (1,1) = 20.0000-49.9925i Y(1,4) = -20.0000 +50.0000i Y(2,2) = 45.3846 -66.3923i Y(2,3) = -13.3333 +26.6667i Y(2,4) = -15.3846 +23.0769i Y(2,5) = -16.6667 +16.6667i Y(3,3) = 20.0000 -39.9795i Y(3,5) = -6.6667 +13.3333i Y(4,4) = 35.3846 -73.0619i Y(5,5) = 23.3333 -29.9700i 57.5% 97.5% 75.5%
