Grid Synchronization of Renewable Generation Systems Using Synchronous Power Controllers
2017 IEEE 6th International Conference on Renewable Energy Research and Applications (ICRERA), 2017The increasing penetration of renewable energy sources in power systems has increased the amount of generating units employing power electronics as their grid interface, instead of synchronous generators. Their different dynamics have brought new challenges for power system operators; in particular, the reduction of the total inertia of power systems ...

A Pre-synchronization Method for Grid-connection Based on Virtual Synchronous Generator
2019 6th International Conference on Systems and Informatics (ICSAI), 2019The inverter is simulated as a synchronous generator that is friendly to large power grid, which can improve the absorption capacity of distributed power supply. However, when virtual synchronous generator (VSG) is connected to the grid, there will be a large current shock. Therefore, this paper proposes an improved pre-synchronization control strategy

Content Synchronization in Replicated Grid Database Resources
2007 Third International IEEE Conference on Signal-Image Technologies and Internet-Based System, 2007Widely used approach to increase data availability and fault tolerance in grid systems is the data replication. Most of the grid data management and data replication solutions deal purely with read-only data sets. There is a lack of the tools that enable the management of updatable grid database replicas.

Luenberger Observer Based Grid Synchronization Techniques for Smart Grid Application
IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020Adaptive observer based grid synchronization technique has received wide attention recently. This technique has fast convergence property. However, adaptive observer is sensitive to unmodeled dynamics e.g. harmonics. Moreover, no small-signal models are available which can be useful for gain tuning purpose.

Synchronization of a single-phase photovoltaic generator with the grid
2011 IEEE EUROCON - International Conference on Computer as a Tool, 2011This paper presents the architecture of a hybrid phase lock loop circuit topology for synchronizing a single-phase inverter fed from a renewable energy source such as a photovoltaic (PV) generator to the low voltage utility grid. The system uses a digital phase lock loop (DPLL) architecture, which is based on the arctan phase detector, driving a phase ...

Virtual synchronous generator: An element of future grids
2010 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT Europe), 2010The future power system integrated a large share of distributed generation (DG) may causes a reduction of the system rotational inertia, resulting in high frequency variations with any disturbances. An additional rotational inertia will be provided to the system if many DG units combined with relative small storage systems operate like virtual ...

Soft synchronization of dispersed generators to micro grids for smart grid applications
2012 IEEE PES Innovative Smart Grid Technologies (ISGT), 2012Fast and proper synchronization of generation stations is becoming inevitable specially in micro grids. Increased number of small generation units raised total quantity of their synchronization process to the micro grids. This Paper provides improvements in synchronization between an emulated power system and its power generation stations in a ...
