日前调度计划优化，根据负荷、风电、光伏、燃气轮机、蓄电池出力计划，安排日前调度出力，以成本最优为目标函数进行调度(Recently scheduling optimization, depending on the load, wind power, photovoltaic, gas turbines, battery output plan arranged before scheduling output, optimal scheduling cost as the objective function)

这是一个火车票分配问题（只有X是未知的） 假设初始座位数为N 分配给AB，BC，AC的座位数量为（xAB,xBC,xAC） 假设在时间t还剩余的A-B,B-C的可售座位数为（a,b） 三个区段的需求DAB,DBC,DAC,是独立的随机变量（也可以给确定的值），其价格分别为（fAB，fBC，fAC）(This is a train ticket assignment problem (only X is unknown). Suppose the initial number of seats is N The number of seats allocated to AB, BC and AC is (xAB, xBC, xAC). Assuming that the remaining A-B in time t remains, the number of seats available for sale is B-C (a, b). Demand DAB, DBC and DAC in three sectors are independent random variables (which can also be given a fixed value), and their prices are (fAB, fBC, fAC) respectively.)
