Insular system management

Maximize the use of solar energy while ensuring grid balancing 

ABOUT

Ensure the stability of insular power grids while maximizing solar penetration

On an island, renewables are usually the only form of energy that can be locally produced. They constitute an interesting choice compared to other conventional sources, as they allow to pursue ambitious energy transition objectives and reduce electricity production cost. However, depending on the location, size and topography of the island, the variability of the solar and wind resources can be quite important. As insular electricity networks are completely isolated, renewable energy sources play a major role in the grid management as their penetration in the electricity mix increases.

Hence, being able to predict significant drops in renewable resources is crucial to compensate for the production decrease with a different energy source and thus guarantee the power quality and grid stability. Solar and wind forecasting at different time scales rises up then as the best practical solution to anticipate the fluctuations in the energy production.

These are our products and services for insular power grids, allowing to get the most of solar and wind energies while ensuring power network stability:

Sizing of energy storage systems (centralized or not)

Analysis of the variability of the solar and wind resource

Estimation of the solar potential of a specific site

Long-term mix strategy

Optimize the management of the grid and the spinning reserves by limiting the impact of the intrinsic variability of renewable energies. 

KEY BENEFITS

Why use wind and solar forecasting for insular system management?

REACH ENERGY TRANSITION REQUIREMENTS

Reduce the carbon footprint of the electricity production mix by optimizing the management of the operating reserves and consequently reducing fossil fuel consumption. 

MINIMIZE THE RISK OF BLACKOUTS 

By anticipating the significant drops in the energy production caused by sudden changes in weather conditions and optimizing the real-time dispatch strategy of the different energy sources, thus ensuring electricity supply.  

REDUCE ELECTRICITY PRODUCTION COSTS 

By using massively renewable energies: the use of fossil fuel will be reduced and the gensets lifespan will be increased, thus reducing their maintenance costs.
