Microgrids and off-grid PV systems are becoming more and more common as there is a concrete will to move towards greener energy sources for remote sites.

Solar energy forecasting for microgrids and off-grid installations enables to more efficiently pilot hybrid systems using both PV and another source of energy, such as diesel generators or thermal plants. The use of a ground camera for intra-hour forecasting helps take the right decisions on when to launch or stop other means of production than solar energy.

 

Save significant amounts of fuel

Thanks to minutely forecasts, the whole installation can considerably reduce its spinning reserve. As a result, forecasting allows for important fuel savings.

Reduce greenhouse gas emissions

By allowing very high variable renewable energy penetration rates, forecasts help lower the consumption of fossil fuels and therefore reduce CO2 emissions. Furthermore, the consumption of locally produced energy avoids losses that would normally occur due to the transportation and distribution of electricity.

Improve system management

When integrated within a microgrid’s energy management system (EMS), solar forecasts enable a better anticipation of energy flows. Thus, an optimal exploitation of the solar potential is achieved.

Technologies

Intra-hour forecasts present the best solution for microgrids and off-grid projects. Reuniwatt has developed two technologies for such forecasts:

  • Sky InSight: our patented imager is a unique ground camera entirely developed by Reuniwatt. Its infrared vision makes it more precise than other standard imagers. Sky InSight captures images every minute and improves intra-hour forecasting for the next 60 minutes. Actually, Reuniwatt has also developed an entirely embedded version, especially for microgrids and off-grid projects. Read More
