Abstract:   (16995 Views)
In this work we use directional enlargement of domain of attraction to increase critical clearing time of nonlinear systems. To find the optimal control parameters, we use measure theory which converts the enlargement problem to a linear programming problem. At first step we find the critical directions of system, along them the system instability happens.  After that we find optimal controlling parameters to extend domain of attraction along directions of interest. The efficiency of the proposed method is verified in simulation part for increasing critical clearing time of a power system with four machines.
