We have proposed the switching adaptive control law for the systems and designed the Lyapunov function in this thesis. It is proved that the proposed switching adaptive control law guarantees the solutions of the nonlinear systems boundedness and convergence of the tracking error to a residual set based on the Lyapunovs stability theory. The residual set can be made arbitrarily small by choosing a certain design parameters.

Then, the sequence voltages of the slack bus is replaced, and finding the positive sequence power flow several times until convergence comes off. Compared with the three-phase Newton-Raphson method, the Jacobian matrix with the proposed algorithm is of much lower order. The computation of finding the negative sequence component from the coupling power is only division arithmetic.
