Improved Newton optimal power flow algorithm

Basing on the Newton Power Flow Algorithm, this paper presents a new method to solve this problem. Considering the active and reactive power of generator nodes and the reactive power of the compensated nodes as the state variables, the improved method calculates P g i and Q g i through Lagrangian multipliers. This method simplifies the way of dealing the inequalities without using of the penalty Functions. Numerical results for example systems show that the new method can accelerate the calculate speed and at the same time get better convergence.
