Abstract

This paper proposes a new power flow algorithm for active distribution systems. The proposed algorithm is developed for both radial and meshed topology based on a globally convergent trust-region method. Different types of loads including constant power, constant current and constant impedance are modeled at the system buses. The mathematical model of distributed generation (DG) connected as PQ and PV buses are integrated into the power flow algorithm to simulate the penetration of DGs in the distribution systems. The proposed method has been tested and compared with the IEEE 37 bus unbalanced test feeder result. A 25 bus unbalanced meshed distribution network has also been used to test the effectiveness of the proposed power flow algorithm in case of meshed networks.
