Performance improvement of decentralized control for bidirectional converters in a DC micro-grid

Decentralized Control Strategy for Optimal Energy Management in Grid-Connected and Islanded DC Microgrids

This paper proposes a decentralized control technique to minimize the total operation cost of a DC microgrid in both grid-connected and islanded modes. In this study, a cost-based droop control scheme based on the hourly bids of all participant distributed generators (DGs) and the hourly energy price of the utility is presented. An economic power sharing technique among various types of DG unit...

Family of multiport bidirectional DC-DC converters

Multiport DC–DC converters are of potential interest in applications such as generation systems utilising multiple sustainable energy sources. A family of multiport bidirectional DC–DC converters derived from a general topology is presented. The topology shows a combination of DC-link and magnetic coupling. This structure makes use of both methods to interconnect multiple sources without the pe...

A Performance Driven Switching Control of DC-DC Converters

This paper reports the application of the switching control method based on the controller performance assessment. The switching of the controllers are done based on the current control performances. The accepted controller has the best estimated performance of all controllers. Finally, the practically and utility of this idea are evaluated by the voltage control result of the DC-DC converters.

Bidirectional DC-DC Converters for Energy Storage Systems

A Markovian Approach Applied to Reliability Modeling of Bidirectional DC-DC Converters Used in PHEVs and Smart Grids

In this paper, a stochastic approach is proposed for reliability assessment of bidirectional DC-DC converters, including the fault-tolerant ones. This type of converters can be used in a smart DC grid, feeding DC loads such as home appliances and plug-in hybrid electric vehicles (PHEVs). The reliability of bidirectional DC-DC converters is of such an importance, due to the key role of the expec...
