英文摘要：

For many application cases, such as voltage adjustment and power flow matching, methods based on bus-type extended load flow calculation can be effective. The application for bus-type extended load flow in voltage adjustment and network power flow matching was studied in this paper. A voltage adjustment method based on bus-type extended load flow was presented firstly. After that, the deficiency in traditional network power flow matching methods was well analyzed. Based on bus-type extended load flow, an efficient power flow matching method was proposed to match boundary power flow between the intemal and external power networks. Numerical tests showed that bus-type extended load flow method could be used to solve the problems of power flow adjustments efficiently.
