Microgrids can bring electricity power to rural communities or isolated military forward operation bases. For many rural areas, renewable powers could be the cheapest power sources available. Utilizing renewable power sources and energy storage systems such as batteries requires new power and voltage control strategies. In addition, these microgrids may be reconfigured frequently. Therefore, th...
The micro-turbines can be used to supply both thermal and electrical energy demands of islanded microgrid. Depleting fossil fuels and ever-increasing environmental concerns have attracted much attention to the renewable energy resources. Meanwhile, the stochastic nature, non-compliance with the load, inability to meet the thermal load and high cost of the wind and solar resources are disadvanta...
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...
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...
