With ultra-high voltage and new energy,new load accessing to the grid,the problem of peak load regulation became more outstanding.A "source-grid-load"interactive peak load regulation method was proposed,in which conventional units,energy storage and flexible load interact each other,and may realize global optimized peak load regulation.The characteristics of three kinds of peak load regulations are analyzed;and their costs are researched.Then the mathematical model of peak load regulation is established.An improved differential evolution algorithm is proposed.Based on the random dynamic characteristics of peak load regulation,every kind of ramping characteristic is considered.And ordering and interactivity,proportionality among"source-grid-load"peak load regulation are realized.Finally,through simulating calculation,the availability of "source-grid-load"peak load regulation is proved.The stability of power grid operation and UHV transmission power is improved.
