6 FAQs about [Microgrid power fluctuations]

Why are power fluctuations a problem in a microgrid?

With the rapid penetration of renewable generation systems and active loads, the stability and reliability of modern power systems face several challenges owing to power fluctuations caused by renewable intermittency and load uncertainty. Power fluctuations are more significant in islanded microgrids that possess low inertia.

Are power fluctuations associated with low inertia in a microgrid?

Power fluctuations are more significant in islanded microgrids that possess low inertia. Therefore, this study proposes a novel cost-effective proactive control strategy to mitigate power fluctuations of an islanded microgrid.

How to improve microgrid operation stability and power supply quality?

In order to enhance the operation stability and power supply quality of microgrids, the application of energy storage systems is imperative. However, the single energy storage system cannot meet the development needs of the microgrid. Therefore, it is necessary to adopt a hybrid energy storage system (HESS) with more suitable performance 6.

What is a microgrid model?

A brief microgrid model is built to collect training data, where the capacity of the PV and load power supply is 20 and 15 kW, respectively; weather, humidity, and power fluctuation data are the input features of the neural network.

What causes power quality issues in microgrids?

The majority of power quality issues, accounting for 80% of cases, are caused by harmonics, flickers, and voltage sag and swell. The inclusion of a voltage source inverter within the microgrid results in the production of harmonics (Dhara et al. 2022), which subsequently degrades the power quality of the system.

Can LSTM predict power fluctuations in a microgrid?
