In this paper, photovoltaic (PV) grid-connected inverter which is the core device in PV grid-connected system has been in depth research.An improved predictive current controller has been developed by the Authors for single-phase grid-connected voltage source inverters (VSI).Based on DSP TMS320LF2407A, a 10 kW single-phase grid-connected inverter has been built in this paper.Thus is aimed at us...

Microturbine generation system is one of the most promising and a fast growing distributed generation sources. It is used in various applications thanks to high efficiency, quick start and high reliability. Combination of the microturbine and storage system (e.g. battery bank) is desirable selection to satisfy the load requirements under all conditions and hence the battery bank can play an imp...

The growing importance of Microgrid in future power systems highlights critical challenges like microgrid control and stability. An islanded including distributed generations (DG), energy storage (ESS), different types loads (static or dynamic) is prone to instability. whole system must be analyzed designed operate within stable regions. This study models an inverter-interfaced which supplies s...

As the use of distributed generation with power electronics-based interfaces increases, separation between DC and AC parts grid is reduced. In such inverter-dominated grids, impedance-based analysis methods are proving to be more powerful than traditional state-space-based methods. Even conventional parameters standards used estimate stability generators stronger grids cannot fully capture dyna...

Australia has seen a strong uptake of residential PV systems over the last five years, with small scale distributed generation systems now accounting for around 10% of peak capacity within the Australian National Electricity Market. As uptake further increases, there is concern about the ability of distribution networks to maintain reliability and power quality without requiring substantial add...

Variation of frequency and voltage by load changes in a microgrid is a challenge in droop control method. Centralized restoration frequency or voltage in a microgrid requires communication link and therefore affects the advantage of decentralized droop control such as reliability, simplicity and inexpensiveness. This paper proposes a decentralized method that restores the frequency of a microgr...
