To achieve accurate reactive power and harmonic currents sharing among inverter interfaced distributed generation (DG) units in islanded microgrids, a hierarchal control scheme consisting of primary and secondary levels based on instantaneous circulating currents is proposed in this paper. Firstly, fundamental and main harmonic components of each inverter output current are extracted at the pri...

In conventional power systems, frequency and voltage deviations are chosen as indexes for characterizing conventional power system security. While  in an autonomous micro grid with Electronically Interfaced Distributed Generation (EIDG), frequency and voltage deviations  against power and loads disturbances perfectly controlled by f-P and V-Q controller. Unlike conventional power syst...

Decentralized Generation (DG) is expected to play a vital role in the future of electric power system. The power electronics interfaced microturbine generation systems are currently attracting lot of attention to meet different needs both at end consumers and the distribution utility levels. Dynamic modelling of the microturbine is a challenging process because manufacturers do not readily prov...

This paper focuses on the problem of voltage control of islanded inverterinterfaced microgrids consisting of several distributed generation (DG) units with parallel structure. The main objectives are to (i) design a decentralized/distributed voltage controller with minimum information exchange between DG units and their local controllers (ii) design a fixed-/low-order dynamic output feedback co...

abstract: in this paper a control scheme for grid-connected operation mode and the island state of distributed generation is presented. in normal conditions, every inverter dg system in micro-grids to supply a preset power, normally operate in a constant current control mode. when micro-grids removed from the network, dg inverter of each system must recognize the island and change position to v...

Modern power systems require increasing intelligence and flexibility in the control and optimization to ensure the capability of maintaining balance between generation and load under violent disturbances. There are several inverter interfaced distributed generations (IIDGs) with local and global control loops in a microgrid (MG). Voltage and frequency of MGs are strongly impressionable from the...

Microgrids (MG) are small-scale electric grids with local voltage control and power management systems to facilitate the high penetration grid integration of renewable energy resources (RES). The distributed generation units (DGs), including RESs, connected (micro) through electronics-based inverters. Therefore, new paradigms required for frequency regulation by inverter-interfaced DGs (IIDGs)....
