Abstract
- This paper proposes a new method to handle distribution transformers of various winding connections in the backward/forward sweep-based power flow analysis for unbidanced radial distribution systems. The method takes advantage of available nodal admittance matrices of distribution transformers, and can automatically solve the problem of conductively isolated subnetwork to obtain their equivalent phase-to-reference voltages. In addition, this paper presents a limitation of back- ward/forward sweeps, and an extension of the power summation method for distribution power flow analysis from single-phase to unbalanced three-phase. The validity and effectiveness of the proposed method can be demonstrations by numerous examples and real systems. [ABSTRACT FROM AUTHOR]
