Multifunctional Smart Microgrid

Can multifunctional inverters improve power quality of smart microgrids?

Silveira, A.H.d., Libano, F.B., Leborgne, R.C. et al. A novel application of multifunctional inverters to enhance power quality of smart microgrids: an analysis on a low voltage and four-wire grid.

What is a smart microgrid?

Smart microgrids (SMGs) are small, localized power grids that can work alone or alongside the main grid. A blend of renewable energy sources, energy storage, and smart control systems optimizes resource utilization and responds to demand and supply changes in real-time 1.

What happens when a microgrid is connected to a power system?

In the first scenario the microgrid is operating connected to the power system. Initially, only the nonlinear load is triggered, later, at \ (t=0.5\) s the multifunctional inverter starts its operation correcting the harmonics, the imbalance of phases and the power factor of the local load.

What are the strategies for energy management systems for smart microgrids?

There are many strategies for energy management systems for smart microgrids such as load management, generation management, and energy storage management 4. The control system of a microgrid must continuously analyze and prioritize loads to maintain a balance between power generation and consumption.

How can a smart microgrid improve safety?

To further fortify the smart microgrid's safety, a theft detection device that tracks the gap between electricity withdrawal and consumption has been implemented. The proposed system also included the management of inverter and smart meter-connected loads, allowing for flexible responses to power outages.

How do self-sustainable microgrids work?

Such self-sustainable microgrids can operate independently from the main grid by harvesting energy from localized sources and regulating and storing the scavenged energy in various energy storage modules.
