联合网电时母管制供热机组热电负荷优化分配策略研究

母管制供热机组为了满足热电的供应常多发电、造成发电过剩的情况，由于热电厂发电仅适用于园区热电负荷，无法发电上网产生收益，不但造成了能源的浪费，而且使运行成本增加。首先，以母管制热电厂运行成本为优化目标，建立了联合网电时母管制系统汽机侧混合类型供热机组负荷优化模型；然后，提出了基于小微增原则，对2种不同情形下混合类型机组的热电负荷优化分配策略进行研究；最后，以某热电厂的热电负荷为例进行优化分配。结果表明，对热电负荷优化后的运行成本低于未优化的运行成本，同时也验证了本文所提基于联合网电时母管制供热机组热电负荷优化分配策略的有效性。

Research on optimal distribution strategy of thermal power load of pipe-main scheme of bus tube heat supply unit in the united distribution network

In order to meet the thermal power supply，the header pipe heat supply unit often generates more power，resulting in excess power generation.As the thermal power plant is only applicable to the thermal power load in the park，it cannot generate electricity on the grid to generate revenue，which not only causes waste of energy，but also increases the operating cost.Firstly，the load optimization model of turbine side mixed type heat supply units in the combined grid is established with the operation cost of the main pipe thermal power plant as the optimization objective.Then，based on the principle of small incremental，the optimal allocation strategy of thermal power load for two different types of hybrid units is proposed.Finally，the thermal load of a thermal power plant is taken as an example to optimize the distribution.The results show that the operation cost of the optimized thermal power load is lower than that of the unoptimized operation cost，and also verify the effectiveness of the proposed thermal power load optimization allocation strategy based on the combined grid of mains heating units.
