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...
متن کاملCooperative 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...
متن کاملPlug-and-play and coordinated control for bus-connected AC islanded microgrids
This paper presents a distributed control architecture for voltage and frequency stabilization in AC islanded microgrids. In the primary control layer, each generation unit is equipped with a local controller acting on the corresponding voltage-source converter. Following the plug-and-play design approach previously proposed by some of the authors, whenever the addition/removal of a distributed...
متن کاملSecondary Control for Voltage Unbalance Compensation in an Islanded Microgrid
In this paper, the concept of secondary control is applied for voltage unbalance compensation in an islanded microgrid. The aim of the proposed control approach is to enhance the voltage quality at the point of common coupling (PCC). Unbalance compensation is achieved by proper control of distributed generators (DGs). The DGs control structure mainly consists of active and reactive power contro...
متن کاملVoltage 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...
