Load Forecasting Based on BP ANN for Economical Operation of Electric Boiler with Heat Reservoir Under Time-sharing price

Along with the generalization of DSM and time-sharing price system, the use of electric boiler with heat reservoir becomes more and more extensive. Load forecasting of heat supply system is an important base in the study of economical operation of electric boiler with heat reservoir under time-sharing price. The BP ANN modeling of the load forecasting for a 1200 kW electric boiler is discussed. The result of hourly heat load forecasting accords well with the real heat load.     

江都站不同型号机组变速优化运行效果分析

以江都站不同型号机组、不同日平均扬程、不同运行负荷组合生成45种方案,并对每一种方案以单机组提水耗电费用最小为目标,采用动态规划法,分别按考虑分时电价与不考虑分时电价进行变速优化计算,同时进行考虑分时电价的常规运行计算,最后以单位提水费用作为分析指标,对不同型号机组变速优化运行效果进行比较分析,其结论为考虑分时电价、长江潮位影响等因素的站群优化理论研究提供决策依据,同时为大中型泵站改造与经济运行提供参考。
