Description

technical field [0001] The invention relates to the technical field of power system scheduling automation, in particular to a real-time power generation plan optimization method considering deep peak regulation of thermal power units. Background technique [0002] With the rapid development of the national economy and the improvement of people's living standards, the installed capacity of the national power grid has also increased, and the national power consumption structure has also changed. The electricity consumption of the primary industry is showing a downward trend year by year, while the electricity consumption of the secondary and tertiary industries is increasing year by year. The peak-to-valley difference is even more prominent, resulting in an increasing range and difficulty in power grid peak regulation. Since the power composition structure of most power grids in my country is dominated by thermal power, and the proportion of hydropower is very small, it has b...
