[0002] The control module of comprehensive energy security has gradually developed with the increase of complexity of energy system equipment and the demand for multi-energy complementarity. Its core lies in the coordinated management and optimized scheduling of multiple energy sources (such as electricity, natural gas, thermal energy, and renewable energy) through advanced control strategies and technical means. Since some remote areas are usually difficult to access the main power grid, the power energy supply is unstable. Therefore, reliable power energy supply is provided to remote areas through microgrid equipment combined with comprehensive energy equipment. When some extreme weather occurs in remote areas, due to the influence of extreme weather factors, the prediction of power consumption and energy demand under extreme weather is inaccurate, resulting in insufficient prediction accuracy, and thus the power generation plan and power scheduling of comprehensive energy equipment cannot be adjusted in advance, resulting in power waste caused by imbalance of supply and demand or excessive power generation of microgrids, and reducing resource utilization efficiency. When the prediction accuracy is insufficient, it is impossible to timely discover the deviation of the predicted power energy demand under extreme weather conditions, resulting in large-scale power outages in remote areas, increasing the losses and inconvenience caused by large-scale power outages, and thus reducing the efficiency and reliability of power energy supply. Therefore, we provide a control module and method for a comprehensive energy security system. Summary of the invention
