Energy Consumption of ADU/VDU in China and Measures for Improvement

The present status of energy consumption ofADU (Atmospheric Distillation Unit)/VDU (VacuumDistillation Unit) in China is discussed, the major problems, such as low end temperature of heat exchange,low heater efficiency, high fuel consumption, and large consumption of water, electricity and steam areanalyzed, and measures for improvement are proposed.

面向能源互联网的未来配电网优化规划

能源互联网是未来全球能源行业的发展方向,其对电力系统的发展将产生深刻影响。文章分析了未来能源互联网场景下配电网的特殊需求,提出未来配电网将发展为承担多能转换与利用的新型配电网,并给出未来配电网的基本构架,分析其能量流动形态。在此基础上,构建考虑多能转换与存储设备成本构成及运行约束的配电网优化规划模型,在满足多能负荷需求的前提下对多能源接口设备与综合储能设备进行优化设计,并利用粒子群算法对该模型进行求解,仿真算例验证了所提模型的有效性,可为未来配电网的发展与规划提供必要参考。
