An Improved Triple Interline DC Power Flow Controller for Bidirectional Power Control
2020 IEEE REGION 10 CONFERENCE (TENCON), 2020For the operational safety and stability of electrical system, effective power flow control in meshed high voltage direct current (HVDC) grids makes sense. In order to realize the objective of controlling several lines simultaneously and independently in a convenient way, interline dc power flow controller (IDCPFC) has been introduced.

Unified stability criterion of bidirectional power flow cascade system
2013 Twenty-Eighth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2013The stability issues of cascade system have been studied for many years. Some classic criterions in the form of Zo/Zi like Middlebrook criterion has been proposed and the validity have been proved in the case like voltage source with a current sink. But they meet the challenge in some application, especially in the case of current source with voltage ...

A novel square-wave converter with bidirectional power flow
Proceedings of the IEEE 1999 International Conference on Power Electronics and Drive Systems. PEDS'99 (Cat. No.99TH8475), 1999A novel ZVS phase-shift controlled bidirectional DC-DC convertor is proposed. It possesses the conventional features of phase-shifted convertors, including constant switching frequency, zero-voltage switching (ZVS) and voltage control by phase-shift. However, the new convertor has been improved by developing a bi-directional power flow capability and ...

Bidirectional power flow control of a power converter using passive Hamiltonian techniques
International Journal of Circuit Theory and Applications, 2007AbstractA controller able to achieve bidirectional power flow for a boost‐like full‐bridge rectifier is presented. It is shown that no single output yields a stable zero dynamics for power flowing both ways. The controller is computed using port Hamiltonian passivity techniques for a suitable generalized state space averaging truncation of the system ...

A bidirectional contactless power transfer system with dual-side power flow control
2012 IEEE International Conference on Power System Technology (POWERCON), 2012This paper proposed a bidirectional contactless power transfer (CPT) system with controllers at both primary and secondary sides to regulate the power flow. By involving energy feedback mode in the converters of both sides, a backward power flow channel from load to source is achieved which helps pumping out the surplus power from the output filter ...
