A bidirectional power flow rectifier with unity power factor based on instantaneous control values
The IEEE Region 8 EUROCON 2003. Computer as a Tool., 2004The paper is focused on a voltage control implementation of a three-phase rectifier (600 V/12 kVA) with unity power factor. In contrast to other known solutions based on microcomputer or DSP control, it introduces a simple control algorithm. It relies on instantaneous control values of three-phase bridge inverter that inherently performs three-phase to

Energy Conversion and Management, 2016
Abstract Due to the intermittent nature of the renewable energy sources including photovoltaic and wind energy, the energy storage systems are essential to stabilize dc bus voltage. Considering the discharge depth of super-capacitors and energy-storage batteries, the bidirectional isolated power interface will operate for a wide range of voltage and ...

2021 IEEE Fourth International Conference on DC Microgrids (ICDCM), 2021
This paper proposes a sensorless link voltage control method for bidirectional power flow controller for next-generation DC power network. In our previous works, we studied methods to keep the link voltage at a constant value. The methods were implemented based on feedback of the measured link voltage values.

IEEE Transactions on Smart Grid, 2020
This article proposes a distributionally robust chance-constrained (DRCC) model for the optimal power-gas flow (OPGF) problem with uncertain wind power. In the proposed model, a unified affine policy is introduced to adjust the flexible resources in both systems for uncertainty mitigation.

A bidirectional power flow controller for EVs to support the grid
2015 50th International Universities Power Engineering Conference (UPEC), 2015The spreading of electrical vehicles leads to a positive impact on the mobility field from the ecological, economical and efficiency point of view. Unfortunately this diffusion is also potentially capable of negative reverberations on distribution and transmission networks, since EVs can be considered as a new load category. Rather than preventing this

IDA-PBC controller for a bidirectional power flow full-bridge rectifier
Proceedings of the 44th IEEE Conference on Decision and Control, 2006A controller able to support bidirectional power flow in a full-bridge rectifier with boost-like topology is obtained. The controller is computed using port Hamiltonian passivity techniques for a suitable generalized state space averaging truncation of the system, which transforms the control objectives, namely constant output voltage dc-bus and unity ...
