or phone notifications for alerts ; telling operators when to turn off an engine and when to turn it back on .
The software is constantly analysing the data and running the math to solve the economic dispatch requirements and unit commitment constraints to ensure grid reliability and high engine efficiency .
Load forecasting integrates the different trends and patterns that are detectable in historic data as well as satellite based solar forecasting to provide a holistic approach to dispatching power . The Fekola site has a sky imager , or cloud tracking camera with a fisheye lens , that provides solar forecasts for the next half hour in high temporal resolution .
To ensure that operators really understand the platform , and have visibility over the advanced controls , the UI provides probability distributions of the solar forecast . Tracking the forecast errors enables operators to see whether the solar is overproducing or underproducing what the forecast was expecting at the time and provides visibility to the operators on the key performance indicators . This feedback is an important part of the machine / human interface and provides operators with insight if an engine is required to be turned on at short notice .
Automated curtailment enables the optimization of the system providing a reactivity that people cannot match . By continually monitoring the engine loadings and battery , the system is ready to clamp down on solar if it gets too volatile or exceeds some spinning reserve requirement . For example , if a large , unexpected cloud arrives , the battery is dispatched to fill the gap while the engines ramp up . Once the cloud disappears however , the engines remain committed to operating for a few hours , and the solar power is transferred to recharge the battery .
Over time , as load patterns shift , the load forecasting algorithm will also be dynamically updating to match the changing realities of the load . As mining equipment hits layers of harder rock , increasing the power load , the system will adjust and dispatch the engines accordingly .
Hybrid solutions will become the new gold standard for off-grid heavy energy users The Fekola mine project incorporates the largest off-grid hybrid power solution in the world , demonstrating the growing case for clean energy and its sustainable and economic potential for mines in Africa and beyond . As the cost of batteries and solar panels continues to become more competitive , hybrid solutions are proving to be a realistic and effective means for increasing energy reliability and lowering operating costs in any context , thus freeing up resources to improve the human condition ; whether through cheaper materials and gainful employment , or by providing broader access to reliable electricity for healthcare , education , and improved quality of life .
