多分区多期望目标寻优的火电机组负荷分配问题

he existing thermal power units load distribution plan is usually formulated by the system-wide fuel consumption and emission minimization. Although the fuel consumption and emission characteristics of the thermal power units are taken into account, the requirements of desired energy conservation and emission reduction regulation goals of the different areas where the unit is located may be different. Therefore, on the basis of coal consumption and pollutant emission expectations, this paper adds multi-partitions factor, and establishes a model for optimal dispatch of thermal power units with the targets of coal consumption and pollutant emission of per kWh electricity in each area, and designing a multi-period, multi-partition, multi-desired objectives optimization algorithm. Cases show that by setting different expected values for objectives of each area and formulating a dispatch plan for thermal power units, the coal consumption and pollutant emission performance of each area can be balanced to a certain extent, so as to give consideration to the assessment of regional differences in energy conservation and emission reduction as much as possible.
