摘要:

现有的分布式供能经济性优化策略并没有很好地协调经济收益和设备运行稳定性之间的关系,基于此问题提出了一种基于两级运行优化策略的新型分布式供能系统,结合用户侧历史运行数据,预测得到各时段的负荷平均值后先进行第1级总量优化,保证优化方案处于收益较高的水平,再将该平均值作为负荷变化基准值进行第2级微增优化,保证各个时段之间设备根据负荷变动所进行调整的过程相对稳定。运行日将系统优先布置成第1级的总量优化方案,在此基础上根据负荷基准值与逐时负荷的差值进行微增调度;同时,经济累加可得到典型日全天的系统总收益,应用Ebsilon工程软件进行系统的模拟仿真,将该两级优化策略与总量优化、微增优化策略的操作可行性和系统经济性进行比较研究,通过计算对比得出不同策略下各个时间段内分布式供能系统总收益及相应的设备调度最优方案。结果表明,该两级优化策略对系统经济性和运行稳定性提供有价值的参考。

Abstract:

The existing economic optimization strategy for distributed energy supply systems does not well balance the economic benefits and equipment operation stability.Accordingly,the operation optimization for dual-source distributed energy supply systems taking two-level strategy is proposed.Based on user-side operational data,average load of each period is predicted and the first level total load optimization is carried out.Then,to ensure the profitability of the optimization scheme,the second level incremental optimization is made by taking the average load as the benchmark of load variation,keeping the scheduling process of equipment adjusting with the load that varies between different periods relatively stable.During daily operation times,the system prefers the first level total load optimization scheme.And on this basis,the incremental optimization scheme will be carried out according to the difference between the reference value and hourly value of load.The total revenue of a typical day is obtained by revenue accumulation.The operation feasibility and system economy of the total load optimization,the incremental optimization and the two-level strategy are compared based on the simulation results carried out by Ebsilon engineering software.The results show that the two-level strategy is of reference value on optimizing system economy and operation stability.
