In the microgrid, virtual synchronous generator technology can significantly enhance anti-interference characteristics of system frequency and bus voltage, as well solve problems insufficient damping low inertia. However, active power oscillation caused by fluctuations grid faults threaten stable operation seriously. Therefore, for an alternating current (AC) microgrid multi-virtual (VSG) paral...

many studies have been done on hybrid vehicles in the past few years. the full hybrid vehicles need a large number of batteries creating up to 300 (v) to meet the required voltage of electric motor. the size and weight of the batteries cause some problems. this research investigates the mild hybrid vehicle. this vehicle includes a small electric motor and a high power internal combustion engine...

DC distribution systems are a typical power electronic system with low inertia, low-rotational kinetic energy, and poor antidisturbance capability when loads fluctuate or parameters change. In this paper, virtual inertia control an additional first-order filtering link is proposed on the basis of P-Udc droop control. The results simulations experiments verify that reduces voltage change rate im...

In this paper a new algorithm based on phasor measurements for estimating the Thévenin Equivalent (TE) and system inertia constant is proposed. The method estimates the network TE seen from a generator terminal and equivalent system inertia constant by means of phasor data that is available at Phasor Data Concentrator (PDC) center. It is shown that the parameters of the TE could be estimated at...

The power system transition to large penetrations of renewable generation has become a core target decarbonisation roadmaps in many countries. However, switching from synchronous variable inverter-based resources prompted technical concerns linked the reduction inertia and short circuit levels. This may result significant deviations frequency bus voltages during fault events. Hence, this paper ...

The ambitious global targets on decarbonization present the need for massive integration of renewable generation in power systems, resulting a significant decrease system inertia. In addition to reduction inertia, transmission Great Britain (GB) faces some unique challenges owing its relatively small capacity, while being decoupled from other systems and with resources largely non-uniformly dis...

Salah satu tantangan utama dengan sistem tersebut akhir-akhir ini adalah downtime sementara selama kesalahan transmisi jaringan 'ac'. Selama pemadaman sesaat, sumber daya berbasis Power Electronic berhenti beroperasi, sehingga menimbulkan kemungkinan keandalan untuk dalam penelitian ini, opsi potensial menyediakan operasi berkelanjutan skenario disajikan pertimbangan mengidentifikasi peningkata...

This study evaluates the performance of a molten carbonate fuel cell and micro gas turbine (MCFC/MGT) hybrid power system bi-fueled by city gas and biogas. The performance of the MCFC/MGT hybrid power system and MFCF/MGT hybrid power system response have been investigated experimentally and numerically. Results show that the MCFC, steam reformer, and catalytic combustor models are in agreement ...
