With China 's sustained and rapid economic development , the power load is climbing electricity peak and valley difference gradually widening China's energy structure coal accounts for four-fifths of the situation , in addition to electricity plans and contradictions of the market for coal , resulting in unprecedented coal supply stress and other problems , to bring greater pressure to the power grid construction and operation . Balanced, to ensure smooth implementation of the national policy of energy-efficient scheduling and energy saving , the protection grid stability, security and ease coal tensions , has become an important issue of the marketing efforts of the municipal power supply company . Face structural , period power shortage situation , only to carry out orderly power to reduce the peak-valley difference through energy-saving power generation dispatching the balance of power system , transmission, distribution and electricity parties relationship , reasonable arrangements for the generator set power generation sequence bit , especially coal-fired units ordered mediator to reduce coal demand . Thesis paper obtained from the user load curve analysis for power systems in recent years , peak and valley difference every year widened to increase the pressure of power system operation , its the to hinder energy conservation scheduling , bring coal consumption too high . Thus orderly power to carry the load side , can significantly flatten the peak load , change load curve , making energy-efficient scheduling can be carried out in a special period . Next papers by specific analysis of energy-efficient scheduling order bits of the sort of generator sets , power generation and coal-fired units , according to the unit to meet the subsequent loading rate by calculating the the economizer effective ordered mediation , the ordered mediation coal-fired units conditions and the decision-making process , \Finally, through the empirical analysis of Luoyang Power Supply Company , verify that the power user orderly power coal demand to reduce the theory of rational and scientific .
