| Abstract: |
It has been conventionally believed that there exist 4 n variables P, Q, V, $$\theta $$ for an n-bus system in the power flow computation, while we have 2 n power flow equations. In this article, the authors argue that the number of variables in an n-bus system is not 4 n but $$4n-1$$ , hence the power flow solution can be obtained without specifying the reference angle of the slack bus. We then deliver a mathematical reasoning why the number of variables in an n-bus system is not 4 n but $$4n-1$$ . [ABSTRACT FROM AUTHOR] |
