The power supply and demand has gradually shifted from overall balance to overall tension, facing the overall situation of "tight balance of the entire network, local gaps, and difficult supply security". If extreme weather occurs or external electricity is lower than expected, the power supply gap will further increase, and the power supply security faces multiple challenges; especially for industrial county power grids dominated by high-energy-consuming industries and enterprises, the problems they face in balancing source and load in different time periods and ensuring power supply are more prominent; therefore, it is necessary to develop a county power supply security system that is easy to operate and use, accurate and efficient.
