Solar Plus Storage Microgrid for Remote Amazon Village

Solar Plus Storage Microgrid for Remote Amazon Village
Vila Restauração in northwest Brazil is now able to access power continuously day and night thanks to the installation of a solar plus storage microgrid. Previously, the village only had access to electricity for 4 hours a day, but international technology company Ingeteam provided equipment and services to install a solar energy supply and storage system.
 
The quality of life for the 750 inhabitants of Vila Restauração in the Amazon improved considerably, having transitioned from a mere 4 hours of electricity a day to an uninterrupted supply. Moreover, the energy they now have at their disposal is clean, as opposed to their previous reliance on a diesel generator unit.
 
This R&D project was developed by Alsol Energias Renováveis ​​(Energisa Group company). The energy generation and storage system consist of four solar inverters with their respective solar panels; four storage inverters with their respective battery banks; two biodiesel generator units and low-voltage switchgear for microgrid automation and protection. For further information see the IDTechEx report on Batteries for Stationary Energy Storage 2021-2031.

System operation

During the day photovoltaic power generation not only supplies electricity to the village but also recharges the batteries that will come into operation to provide power during the night.
 
 
When it is cloudy, the battery charge is low and the photovoltaic system cannot provide enough energy to power the village and recharge the batteries, at which point the generator unit is activated to provide the necessary energy and also to charge the batteries.
 
The entire operation of this microgrid, consisting of a generation system on the one hand and an energy storage system on the other, is automated. This enables systems to be created in which photovoltaic energy generation can be adjusted by varying microgrid frequency to avoid overloading battery banks and meet the demand of the residents, thus achieving a balance between energy generation, consumption and storage.
