Research Progress of Calculation and Practical Calculation Methods of Power System with UPFC

Application of unified power flow controller (UPFC) to power system has become an inevitable trend in the future and related research has achieved certain breakthroughs including theoretical research on calculation of power system after UPFC configuration. However, the fact is not suitable that there is no research overview on calculation and no practical calculation method of power system with UPFC. To this end, this paper summarizes research progress of calculation methods of power system with UPFC from the aspects of power-flow calculation, steady state simulation, transient state simulation, comprehensive calculation, short-circuit current calculation and auxiliary calculation. On this basis, related calculation methods such as steady state calculation, transient state calculation, short circuit calculation and calculation of UPFC adjustment range are discussed which can be used in actual engineering. The work done in this paper aims to provide an overall summary and several practical calculation methods for the research field on calculation of power system with UPFC.
