Hence, to deal with the aforementioned issue, we suggest the development of an optimal fractional sliding mode control (FSMC)-based frequency stabilization strategy for an industrial hybrid microgrid.
Adaptive virtual inertia control is proposed to enhance frequency stability in a microgrid under different disturbances. During designing, performance index, RoCoF, frequency zenith, and frequency nadir have been
Based on the frequency dynamic behaviors characteristic and the real-time values, the frequency stability control strategy of the microgrid system is divided into three zones, including stable
Microgrids (MG) take a significant part of the modern power system. The presence of distributed generation (DG) with low inertia contribution, low voltage feeders, unbalanced loads, specific
Because maintaining power supply and load balance are very vital by microgrid itself. In the islanded mode, microgrid stability is categorized into the voltage stability and frequency stability in both the transient and small signal studies. A linearized model of the network is used for the analysis of small signal stability in the microgrid.
The Microgrid stability classification methodology proposed in this paper considers some important issues that influence the Microgrid performance, such as the operation mode, disturbance types of Microgrid, time frame and physical characteristics of the instability process.
Frequency regulation in a microgrid operating in autonomous mode is critical because of the intermittent nature of the renewable sources employed. To maintain the frequency regulation within a tolerance limit in a microgrid, proper control schemes have to be adopted in order to increase or decrease the real power generation.
Due to the microgrid operation mode, its stability problems are categorized into grid-connected and islanded stability issues. In the grid-connected mode , the stability issues of the microgrid in transient and small signal studies are focused more on voltage stability.
In this paper, a Microgrid stability classification methodology is proposed on the basis of the of Microgrid characteristics investigation, which considers the Microgrid operation mode, types of disturbance and time frame.
The small signal stability, transient stability, and stability improvement methodologies are summarized systemically, which is helpful to establish the research framework of Microgrid stability. The challenges of Microgrid stability study discussed at last could give valuable suggestions for the further researches.
