The Necessity of Building Pumped-Storage Plant in Shandong Power Grid
In this paper, the features of power sources structure and present situation of peak load regulation in Shandong power grid are described. According to the peak generation capacity, the requirement of Shandong power grid on pumped-storage plant in Shandong power grid are researched in detail. Research results show that the substitution effect of fossil-fuelled power plants by pumped-storage plants will be significant and the latter will give full play to electric power balance. By means of building pumped-storage plants the peak load regulating capacity and spinning reserve capacity of Shandong power grid will be increased, thus the coal con- sumption rate of thermal power unit will be decreased. Beside, the pumped-storage plant can be used for fre- quency regulation, phase regulation, emergency reserve an black start, so it will play important role in both the security of electricity market and power grid marketing. Thus it is necessary to build pumped-storage plant in Shandong power grid.
