Question

A 12 bus power system has 3 voltage controlled buses the dimensions of the jacobian matrix will be

Answer 1

Answer:

the jacobian matrix will be 19 x 19

Explanation:

The expression  to calculate jacobian matrix is,

2(n-1)-m x 2(n-1)-m

where n is the number of bus, m is the voltage controlled

According to the problem, 12 bus power system has 3 voltage controlled buses

For this problem, n= 12 and m = 3

therefore the jacobian matrix will be,

2(12-1)-3 x 2(12-1)-3

= 19 x 19
