And along with the adjustment of the industrial structure, power structure there occurs the change of essence, and electricity consumption-power supply relation changes, and causes electrical network peak-valley difference day by day to increase.The peak-to-valley ratio of General development Chinese Home is 1:0.63, and the peak-to-valley ratio of developed country is 1:0.25, and the load peak-valley difference of each electric power system transprovincially of China is generally about 30% ~ 40% of peak load.
Because the current national conditions of China and the restriction of varied reason cause China can not make up peak-valley difference by the extensive peak regulation Intelligent Power Station (hydroenergy storage station, plant gas, oil fired power plant etc.) that utilizes as developed country, even if dope electric power value, peak regulation Intelligent Power Station can be used, its energy conversion efficiency is also only 75%, has the energy of 25% to be wasted.Therefore the peak regulation task that faces of China and pressure are just increasingly severe.
But the limitation of equipment makes peak valley flexibly regulate to be restricted, and can only process according to means such as planning in advance, and variable monitoring that can not be real-time.
