Complex Vector Load Flow

ABSTRACT

A complex vector approach to the load flow problem with two important and unique contributions is presented. Traditionally, the intermediate calculations for the Newton-Raphson solution of the load flow problem require operations on elements of matrices (as opposed to operating on vectors themselves). In this approach all intermediate calculations are performed by conventional vector operations plus one other operation. Therefore, only a specific set of operations requires optimization to make the entire algorithm more efficient. This is particularly useful for array processor applications and dedicated VLSI circuitry. In addition, this approach allows far easy inclusion of tap changing transformers and phase shifters into the analysis. A more concise and understandable load flow problem Statement is presented, which ultimately results in dramatic improvements in computation efficiency, making microcomputers able to perform load flow calculations faster than minicomputers.
