Wind power DC grid and Variable Speed DC power system operating control
Proceedings of The 7th International Power Electronics and Motion Control Conference, 2012VSC-HVDC power transmission system that connected long-distance high-capacity wind farm to the grid will be an important direction of the wind power technology development. The grid access solutions designed according to traditional AC grid structure could not fully reflect the advantages of the VSC-HVDC transmission. Firstly the typical grid solutions

IEEE Transactions on Smart Grid, 2018
In the grid-connected mode, the dc microgrid is connected to the utility by parallel bidirectional power converters (BPCs), which provide voltage support for the dc microgrid. The coordination control for these parallel BPCs is very challenging.

Power interchange by the DC bus in micro grids
2015 IEEE First International Conference on DC Microgrids (ICDCM), 2015In this paper, DC power interchange is confirmed to reduce the battery damage by according to the fluctuations in the battery voltage in each micro grid. We investigated various conditions that constructed the DC power interchange system in two micro grids using the DC power flow controller.

Power flow control devices in DC grids
2012 IEEE Power and Energy Society General Meeting, 2012A HVDC grid based on voltage source converters (VSC) is an attractive solution for the grid-integration of offshore renewable energy, interconnection of AC grids, facilitation of power markets, and energy emergency support. However, the power flow within the DC grids is determined by the line resistance, and cannot be fully controlled by the VSCs only.

Characterization of a DC grid for Power Line Communications in smart grids
2014 IEEE 15th Workshop on Control and Modeling for Power Electronics (COMPEL), 2014This work deals with the characterization of a power line, devoted to energy distribution and supplied by DC voltage, aiming to use the same line for exchange of information by means of a Power Line Communications (PLC) system. For this purpose, the DC power grid has been considered as a transmission line.

Unified ship power grids with alternators and DC power distribution
2017 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2017Nowadays, diesel and turbo-generator sets operated with a constant speed are most widely used as marine power sources. Advantages of standard generator sets include a relatively high efficiency. When generator set is operated as a part of the unified electric power grids with an electric propulsion system and load varying within a wide range ...
