چکیده
With the growing shift toward renewable energy, attention focused on disadvantages of current control inverter-based distributed generators, such as lack grid-forming ability and inertia. To provide inertia support ability, virtual synchronous generators (VSGs) have been proposed. Various methods related to VSGs reported, various research challenges evaluated. However, only a few experimental demonstrations addressed. Recommended practices for were launched IEEE Standard Project 2988 March 25, 2021, with considered be new technology that is nearly ready put into practical use. Therefore, real-scale grid are important establishing technical standard VSGs. In this study, was built by simulating an actual microgrid approximately 1:1 power capacity scale. simulated grid, 125 kVA provided diesel SG, five 20 inverters battery energy system (BES) used, generation penetration inverter BES units achieved 44.4%. Six different scenarios operation forming (GFM-BES) following (GFL-BES) evaluated comparatively. System inertia, transient steady state sharing characteristics affected degrees GFM-BES under sudden load change demonstrated. Moreover, forming, synchronization, frequency regulation, regulation demonstrated through field tests. The simulations experiments also constant which expected helpful future topic. findings paper instructions engineers model, design, test generators.

A Power Sharing Method for Parallel Inverters with Virtual Synchronous Generator Control Strategy
Abstract A new power sharing method of a virtual sychronous generator control based inverters is introduced in this paper. Since virtual synchronous generator has virtual inertia and damping properties, it significantly enhances the grid stability. However, its output power considerably affects by the line impedance. Thus, in this paper, the relation between the droop control and the line imped...
متن کاملDoubly Fed Induction Generator and Conventional Synchronous Generator Based Power Plants: Operation during Grid Fault
The use of doubly fed induction generator in wind power plants has result in new necessities to maintain a reliable operation of the network. The tendency of the grid codes is to require the ability from the wind power plant to keep connected during and after grid disturbance, similarly to the synchronous generators requirements. This paper analyse the behaviour of a wind power plant equipped w...
