Microcontroller Graduation Project Lithium Battery Energy Storage

What are lithium-ion batteries & how do they work?

Energy storage through Lithium-ion Batteries (LiBs) is acquiring growing presence both in commercially available equipment and research activities. Smart power grids, e.g. smart grids and microgrids, also take advantage of LiBs to deal with the intermittency of renewable energy sources and to provide stable voltage.

Are lithium-ion batteries suitable for energy storage?

Long-term (two years) experimental results prove the suitability of the proposal. Energy storage through Lithium-ion Batteries (LiBs) is acquiring growing presence both in commercially available equipment and research activities.

Can battery energy storage reduce microgrid operating costs?

By adding battery energy storage (BES) to a and proper battery charge and discharge management, the microgrid operating costs can be significantly reduced. But energy storage costs are added to the microgrid costs, and energy storage size must be determined in a way that minimizes the total operating costs and energy storage costs.

Is a lead-acid battery included in a microgrid?

A Lead-Acid Battery (LAB) is included in the microgrid but there is no data reported about its operation. A monitoring system for microgrid including a Vanadium Redox Flow Battery (VRFB) is designed in . The proposal combines a Raspberry Pi with commercial energy meters, and web platform ThingSpeak to display data.

What time does a microgrid charge a battery?

The battery is charged at 3 and 8 o'clock when the energy price is relatively low, and at 17 and 19 o'clock when the energy price is the highest value, it is discharged and part of this power is delivered to the grid and profitability is achieved for the microgrid.

What is a battery management unit (BMU)?

These batteries are equipped with Battery Management Unit (BMU), also called Battery Management System (BMS), built by the manufacturer and devoted to measuring magnitudes like voltage, current and temperature, cell balancing, as well as to control the charge/discharge cycles under safe conditions.
