Microgrid load fluctuation

How can a microgrid respond to unplanned power fluctuations?

Thanks to the forecast data of source and load in the day-ahead and real-time phases, the microgrid under the M2 strategy can respond to unplanned instantaneous power fluctuations of source and load that are not taken into account in the day-ahead phase.

Why should a microgrid controller be able to handle load changes?

Load changes are always noticed by the microgrids and the microgrid controller must be able to quickly dampen the frequency fluctuations caused by the imbalance of production and power consumption in the shortest possible time and with the least fluctuations.

Does microgrid load optimization work in active distribution network?

The microgrid in the active distribution network is mainly composed of Distributed Generation (DG) units, mainly including renewable energy power generation (PV, WT) and ES systems. To verify the superiority of the study scheme, two microgrid load optimization control schemes are analyzed and compared.

How to improve microgrid stability?

To enhance microgrid stability, this control level must exhibit a suitable and efficient dynamic response to changes in power sources and loads. While the primary control loop governs the drooped frequency, it cannot directly restore the frequency to its nominal value.

How to control the frequency of a microgrid with distributed generation sources?

In this section, the frequency model of a microgrid with various distributed generation sources is first implemented to control the microgrid frequency. The proposed RANFIS controller is designed to reduce fluctuations in the microgrid frequency compared to other controllers.

How can ranfis control the frequency of a microgrid?

Our proposed control strategy is based on the Recurrent Adaptive Neuro-Fuzzy Inference System (RANFIS). This controller can dynamically adjust the active power output, thereby assisting in frequency control within the microgrid.
