Grid Fault Analysis of Unbalanced Loaded DFIG
Advanced Materials Research, 2012The electrical energy consumption is rising and there is a steady increase in the demand of power generation. To meet the demand fuel reserves are not sufficient. So, we can go to non-conventional energy sources like solar, tidal, wind and etc. In that wind generating system is rapidly growing one.

2019 IEEE Industry Applications Society Annual Meeting, 2019
In this paper, Modular Multilevel Converter (MMC) is considered for integrating the giga-watt PV farms with the power grid. In the considered MMC configuration, the PV panels are directly connected across the sub modules of MMC. This MMC-configuration suffers from power imbalance between the arms, phases or both due to non-uniform illumination of the ...

Unbalanced Three-Phase Optimal Power Flow for Smart Grids
IEEE Transactions on Industrial Electronics, 2011Advanced distribution management system (DMS), an evolution of supervisory control and data acquisition obtained by extending its working principles from transmission to distribution, is the brain of a smart grid. Advanced DMS assesses smart functions in the distribution system and is also responsible for assessing control functions such as reactive ...

Learning parameters and topology in unbalanced distribution grids
IET Conference Proceedings, 2022The methods proposed in this paper aim at learning the parameters and topology of a distribution grid by making use of available system measurements. The methods that are used rely on the formulation of the underlying physical equations as linear systems and use the resulting problem as a regression problem by applying the ordinary least squares method.

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
In this paper, an improved grid voltage modulated control (GVM) with power compensation is proposed for grid-connected voltage inverters when the grid voltage is unbalanced. The objective of the proposed control is to remove the power ripple and to improve current quality.

Small-Signal Stability of MMC Grid-Tied System Under Two Typical Unbalanced Grid Conditions
IEEE Transactions on Industry Applications, 2021The AC transmission network of Modular Multilevel Converters (MMC) usually adapts the overhead line, so the single-phase grounding faults of the AC side are rather general. At this time, the protection system will cut off the fault line for the first time, so there are two unbalance grid conditions (UGCs), i.e.

Voltage Source Converter Control Under Unbalanced Grid Voltage
2021The conventional control of the voltage source converter (VSC) assumes that the input voltage is balanced. However, unbalanced voltage is a phenomenon that occurs frequently in actual industrial sites. If the grid voltage is unbalanced, THD increases due to voltage negative component, and low harmonic components appear in DC-link voltage, which ...

Impact of unbalanced grid conditions on PV systems
IEEE PES General Meeting, 2010With more and more photovoltaic (PV) panels, energy storage devices and other small generators being put into service, it is necessary to integrate them into power systems. Grid integration provides a reliable means for customers to use renewable energy such as solar at its maximum and to use other sources as backup.

Unbalanced faults analysis in grid - Connected PV system
2014 IEEE International Conference on Power and Energy (PECon), 2014A search for replacement of non-renewable energy leads to a new founding that is renewable energy which is unlimited energy source. One of the renewable energy is solar energy where photovoltaic (PV) array is used to convert the energy from the sun to electrical energy. PV is widely use in the grid-connected system nowadays.
