(pointB2) varies in a wide range, which indicates that the line power is insufcient.

For improving the situation, it is possible either to strengthen the line with the paral-

lel wire or to use SVC that is made in the model under consideration.

Set the breaker Br3 in the state “closed,” and the simulation time and the transi-

tion times of the closed breakers Br1 and Br2 are equal to 2 s. Set Switch in the

lower position (the angle α is determined by the block alpha_ref). The initial value

is 0, and the nal value is 90 in this block. Rate Limiter settles rather slow chang-
