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

Synchronization Strategy for Virtual Synchronous Generator based Energy Storage System
IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019Due to the ability to improve system inertia of converter-dominant network, virtual synchronous generator (VSG) control strategy has earned it more concern and wide application recently. However, since the VSG can establish the voltage and phase by itself, it becomes crucial for VSG to switch from islanded mode to grid-connected mode smoothly to reduce

A Simplified Synchronous Machine Model for Virtual Synchronous Generator Implementation
2019 IEEE Power & Energy Society General Meeting (PESGM), 2019Virtual Synchronous Generator control of inverters is one of the promising solution to the insertion of renewable energies on Microgrids which still insure the system's stability. In this paper an improved synchronous machine model for the VSG-based inverter is proposed. The model represents the dynamics of the synchronous machine and has the advantage

Synchronous frequency resonance of virtual synchronous generators and damping control
2015 9th International Conference on Power Electronics and ECCE Asia (ICPE-ECCE Asia), 2015The Virtual Synchronous Generator (VSG) is an effective solution for high-penetration renewable energy sources integrated into the power system. Although the VSG has a similar behavior as the conventional synchronous generator, the fast and flexible control capability of converters may give rise to some specific characteristics.

Challenges in Implementation of Virtual Synchronous Generator
2018Grid-connected distributed energy resources (DERs) along with conventional power plants are the best solution to meet the increasing energy demand. But higher penetration level of these DERs may affect the system stability and its performance. DERs do not contribute any inertia unlike synchronous generators (SG) use conventionally.

Re-synchronization Capability Analysis of Virtual Synchronous Generators in Microgrids
2019 IEEE Energy Conversion Congress and Exposition (ECCE), 2019Since distributed energy resources (DERs) are widely connected to the system resulting in the reduced inertia of microgrid, converters are controlled as virtual synchronous generators (VSGs) to emulate the dynamic response of traditional synchronous generators.

Measurement and remote monitoring for virtual synchronous generator design
2010 IEEE International Workshop on Applied Measurements for Power Systems, 2010The future power system will integrate widely distributed energy resources (DER) interfaced by power electronics units, which may cause a reduction of the system inertia, resulting in non-compatibility with existing control algorithms and settings. Additional rotational-inertia can be provided to the system if many DER units combined with relative ...

Stability analysis for coupled synchronous generators with virtual friction
2017 22nd International Conference on Digital Signal Processing (DSP), 2017We investigate the stability of a microgrid composed of two identical synchronous generators, inductive lines and resistive loads, without using any model reduction for “fast” variables. We derive sufficient conditions for local exponential stability, with a region of attraction that includes any initial state such that the states of the generators are
