Radial Distribution Systems Power Flow with Distributed Generation: Modified Power Summation Method

In this work, the Power Summation Method is adapted to be applied in distribution systems that include distributed generation. The voltage control at the generation buses is treated as an optimization problem, which uses the Newton-Raphson method as the minimization technique. The algorithm is iterative and includes the reactive and voltage limits constraints for each generator. The accuracy and computational efficiency of the proposed method were evaluated by comparing its performance with the Newton-Raphson conventional power flow. The test system was a 36 buses feeder with two generators installed.
