Short-term optimal operation methods of large-scale hydropower plants III. Solution method of peak load regulation for multiple power grid

With the development of the scale of power grids and hydropower systems in China, the problem of peak load regulation for multiple power grid will be more and more prominent. On the background of hydropower system of China Southern Grid (CSG), a peak load regulation model for multiple power grid with large scale hydropower systems is proposed. Aggregated function and multi-objective fuzzy optimization model are adopted to establish a fungible objective. A successive associated search method is proposed to address the problem of many time coupling constraints. Practice operation study shows that the method yield practicable results, and is feasible to peak load regulation problems for multi power grid.
