电力市场环境下调度部门如何在保证系统可靠性的同时保证调度的公平性,这是一个亟待解决的问题。设计了一种新的发电机组检修计划制定模型:首先由各发电公司根据机组的检修周期、运行情况、对未来电价水平的预测和调度部门公布的未来各时段的最大检修容量,在规定的时间内上报机组的检修起始时间、检修持续时间、检修容量和检修报价;然后调度部门根据各发电公司的报价,对能够满足系统可靠性要求的检修机组按照报价从高到低的顺序安排检修,并收取相应的费用,而其余检修机组则按照等备用原则进行安排;最后调度部门将所收取的费用按照类似并联电路电流分配原则返还给各发电公司,从而确保其非盈利性。文中所提出的模型,既充分体现了发电公司的检修自主权,又保证了系统的安全可靠和调度的公平性。
How to ensure the system reliability and ensure the fairness of dispatching in the dispatching department in the electricity market environment is an urgent problem to be solved. A new design model of generator maintenance plan is proposed. First, each generation company, based on the maintenance cycle of the generator set, operating conditions, the forecast of the future price level and the maximum overhaul capacity in each future period promulgated by the dispatching department, Within the unit reported the maintenance start time, overhaul duration, overhaul capacity and maintenance quotations; and then dispatch department based on the price of the power generation company, to meet the system reliability requirements of the maintenance crew in accordance with the order of arrangement of the order from high to low overhaul, And charge the corresponding fees, while the other overhaul units are arranged according to the principle of standby. Finally, the dispatching department will return the collected fees to the power generation companies according to the principle of parallel circuit current distribution so as to ensure their non-profitability. The model proposed in this paper fully reflects the autonomy of power company in maintenance and also ensures the system’s safety and reliability and the fairness of dispatching.
