Summary: In this paper, a real-time energy optimization method based on digital twin technologies is proposed. It integrates geometry, physics, production behavior, simulation rules, and data interaction to construct a digital twin-based real-time simulation method. By considering energy consumption characteristics and production equipment behaviors, a real-time energy optimization model is constructed, with an effective solving algorithm based on genetic algorithm. The practical implementation in a shell production line shows that this method has practical value and guiding significance to improve the efficiency of production lines.

Summary: Sudan is facing an energy crisis with a large deficit in electricity supply and transportation fuels. Access to electricity is only available to about 32% of the population. The removal of fuel subsidies has led to significant price hikes. Sudan urgently needs to develop its biomass resources to mitigate the energy crisis and produce synthetic fuels through biomass gasification.
