摘要

Abstract

As one of the new generation flexible AC transmission systems (FACTS) devices

the interline power flow controller (IPFC) has the significant advantage of simultaneously regulating the power flow of multiple lines. Nevertheless

how to choose the appropriate location for the IPFC converters has not been discussed thoroughly. To solve this problem

this paper proposes a novel location method for IPFC using entropy theory. To clarify IPFC's impact on system power flow

its operation mechanism and control strategies of different types of serial converters are discussed. Subsequently

to clarify the system power flow characteristic suitable for device location analysis

the entropy concept is introduced. In this process

the power flow distribution entropy index is used as an optimization index. Using this index as a foundation

the power flow transfer entropy index is also generated and proposed for the IPFC location determination study. Finally

electromechanical electromagnetic hybrid simulations based on ADPSS are implemented for validation. These are tested in a practical power grid with over 800 nodes. A modular multilevel converter (MMC)-based IPFC electromagnetic model is also established for precise verification. The results show that the proposed method can quickly and efficiently complete optimized IPFC location and support IPFC to determine an optimal adjustment in the N-1 fault cases.
