Abstract. With the development of rectification technology and DC equipment, hybrid DC-AC transmission has arisen in the distribution network. In addition, the penetration of distributed generation (DG) in the distribution network makes the analysis of power system more complicated. As a key measure of grid programming and operating, a practical power flow method of DC-AC distribution network is urgent to study. Firstly, the mathematical model of DGs is given in this paper, and the analysis of the operation and control mode of DC-AC distribution system with voltage source converter (VSC) is conducted. Then a calculation method of hybrid DC-AC distribution system with DGs is proposed, in which constant-power DG, voltage controlled DG and DG with voltage static characteristic is concerned. An improved forward backward sweep method is given, concerning VSC, AC circuits, DC circuits and various type of DGs, which achieves the purpose of unified DC-AC power flow calculation. Finally, case study for a 90-node distribution network with DG integration is conducted to demonstrate the effectiveness of the method.

“…However, all its fascination this theory fails to describe the operation of the STATCOM from its DC side. Some obvious disadvantages of the STATCOM model based on the equivalent voltage source concept are: 1) no easy way to determine whether voltage source converter's operation is linear or not [10]; 2) switching losses tend to be neglected and 3) the ohmic losses of the converter internally along with the converter's magnetic are lumped together with those of the interfacing transformer, more often is a tap changer. This endowed to develop realistic STATCOM model for fundamental operation in frequency domain [1]; one which overcomes the disadvantages of the equivalent voltage source and suitable for gauging both conventional multi-level and modular multi-level converters (MMC) [11,12], on large power networks and in an optimal manner.…”

“…Nevertheless, for all its attractiveness this concept fails to explain the operation of the STATCOM from its DC side. Some of the most obvious shortcomings of the STATCOM model based on the equivalent voltage source concept are: (i) there is no easy way to ascertain whether or not the converter's operation is within the linear region of operation [10]; (ii) switching losses tend to be neglected; (iii) the internal ohmic losses of the converter along with the effects of the converter's magnetics are normally lumped together with those of the interfacing transformer which, more often than not, is a tap changer. This has provided the motivation to develop a more realistic STATCOM model for fundamental frequency operation [1]; one which overcomes the limitations of the equivalent voltage source representation and is suitable for assessing the impact of both conventional multi-level and modular multi-level converters (MMC) [11]- [12], on large power networks and in an optimal manner.…”
