考虑增量用电负荷分配的煤改电/煤改气联合分阶段规划

随着我国供暖改造规模的不断扩大,如何根据各种供暖方式的优势及特点研究最优的清洁化供暖改造方案对于我国能源结构转型,缓解环境危机具有重要意义。提出了一种考虑增量用电负荷分配的"煤改电"、"煤改气"联合分阶段规划方法。首先,基于发电能源结构和清洁能源实际发电量构建了"煤改电"增量用电负荷分配模型,精细化分析"煤改电"产生的新增电量。然后,以"煤改电"、"煤改气"分阶段改造方案为决策变量,以用户供暖支出的经济成本、供暖改造的环境成本和能源成本为优化目标,构建"煤改电"、"煤改气"联合分阶段规划模型。最后,利用向量序优化算法对模型进行求解。仿真结果验证了所提方法的正确性和有效性。

Joint staged planning of coal-to-electricity/coal-to-gas considering incremental electricity load distribution

With the continuous expansion of the scale of heating transformation in China, it is of great significance to study an optimal clean heating transformation scheme according to the advantages and characteristics of various heating modes for the transformation of energy structure and mitigation of an environmental crisis. In this paper, a joint staged planning method of "coal-to-electricity" and "coal-to-gas" considering incremental electricity load distribution is proposed. First, based on the energy structure of power generation and the actual power generation of clean energy, an incremental load distribution model of "coal to electricity" is constructed to analyze the incremental power generated by "coal to electricity" in detail. Then, taking the staged planning schemes of "coal-to-electricity" and "coal-to-gas" as decision variables, and taking the economic cost of user heating expenditure, the environmental and energy cost of heating reconstruction as optimization objectives, a joint staged planning model of "coal-to-electricity" and "coal-to-gas" is established. Finally, the model is solved by a vector order optimization algorithm. The correctness and validity of the proposed method are verified by the simulation results.
