Microgrid fuzzy energy storage optimization

How a microgrid based on FQL can improve energy storage?

In general, the microgrid system based on FQL algorithm can better control the SOC of the energy storage system within a reasonable range, which effectively reduces the phenomenon of light discarding caused by the high SOC of the energy storage system on a continuous sunny day, and significantly reduces the use of fossil energy.

What is the fuzzy rule set for operating microgrid?

The Fuzzy rule set defined for operating microgrid comprising of a sustainable renewable energy system are determined by renewable power availability, SoC, load demand, battery condition, renewable energy status, and grid condition.

How to optimize the operation of a microgrid?

Microgrids are fundamental for the incorporation of distributed energy storage systems and renewable distributed power sources. To achieve the goal of optimizing the operation of the microgrid, it is necessary to minimize two optimization criteria, namely operating expenses and detrimental polluting substances.

How does fuzzy control work in a microgrid system?

By employing fuzzy control, the battery SOC can be maintained within the allowed boundary and extend the life of Li-ion batteries. The fuzzy controller output is either in discharging mode or charging mode for the microgrid system in order to obtain the preferred SOC value. The SOC is controlled by changes in the battery current.

Can microgrids improve energy management in Malaysia?

Through the integration of fuzzy logic control with various optimization methodologies, microgrids in Malaysia can attain effective energy management, reduced expenses, and improved system reliability 6, 7, 8, 9, 10. However, it is hard to optimize the operation that involves the integration of an EMS and microgrid for the control system.

How can a microgrid improve power quality and stability?

Merging two different types of renewable sources and two storage systems of different characteristics such as energy density and power density to improve the power quality, reliability, and stability of the microgrid leads to a more complicated time-varying system.
