A Multi-Agent Based Distributed Economic Droop Control for Islanded Microgrid

Artificial Neural Network Based Droop-Control Technique for Accurate Power Sharing in an Islanded Microgrid

In an islanded microgrid, while considering the complex nature of line impedance, the generalized droop control fails to share the actual real/reactive power between the distributed generation (DG) units. To overcome this power sharing issue, in this paper a new approach based on feed forward neural network (FFNN) is proposed. Also, the proposed FFNN based droop control method simultaneously co...

Voltage Imbalance Compensation for Droop-Controlled Inverters in Islanded Microgrid

In this paper, a new control strategy is proposed for implementation in low-voltage microgrids with balanced/ unbalanced load circumstances. The proposed scheme contains, the power droop controllers, inner voltage and current loops, the virtual impedance loop, the voltage imbalance compensation. The proposed strategy balances the voltage of the single-phase critical loads by compensating the im...

Droop Controller Limitation for Voltage Stability in Islanded Microgrid

The motivation to develop microgrids (MG), as a particular form of active networks is explained and presented as an effective solution for the control of grids. In MGs, with high level of penetration of Distributed Energy Resources, the stability becomes an important issue. Some control characteristics of elements such as droop coefficients in VSI highly affect voltage and frequency stability. ...

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...
