A Cyber-Physical Security Analysis of Synchronous-Islanded Microgrid Operation

Coordinated Control Strategy for Microgrid in Grid-Connected and Islanded Operation

As usual, the microgrid operates in grid-connect mode, but, when a fault occurs in the upstream grid, it should disconnect and shift into islanded operation mode. In grid-connect mode, the controlling power at the PCC is necessary management function rather than the frequency and voltage. However, the controlling the frequency and voltage is asked in islanded mode. To achieve these management g...

Voltage Control and Load Sharing in a DC Islanded Microgrid Based on Disturbance Observer

Increasing DC loads along with DC nature of distributed energy resources (DERs) raises interest to DC microgrids. Conventional droop/non-droop power-sharing in microgrids suffers from load dependent voltage deviation, slow transient response, and requires the parameters of the loads, system and DERs connection status. In this paper, a new nonlinear decentralized back-stepping control strategy f...

Gain Scheduling Control of an Islanded Microgrid Voltage

The aim of this research study has been to design a gain scheduling (GS) digital controller in order to control the voltage of an islanded microgrid in the presence of fast varying loads (FVLs), and to compare it to a robust controller. The inverter which feeds the microgrid is connected to it through an inductance-capacitor-inductance (LCL) filter. The oscillatory and nonlinear behaviour of th...

Cooperative Load-Shedding Control of Agent-based Islanded Microgrid

A Key component to future smart grids may be a microgrid system capable of integrating generation, load, and storage assets into an autonomous power system entity. A microgrid is intrinsically distributive in nature. In order to improve performance of a microgrid, a distributed and cooperative control is required. Agent technology is one of techniques for achieving the objectives of distributed...
