王成山：园区型综合能源系统多时间尺度模型预测优化调度

在冷/热/电综合能源系统中，协调多种设备使其优化运行，经济可靠地满足系统用能需求十分重要，制定合理有效的调度策略是实现这一目标的关键。该文针对一个实际园区综合能源系统冬季运行优化调度问题进行研究。在对设备进行详细建模基础上，建立包含滚动优化环节和动态调整环节的两阶段多时间尺度模型预测控制调度策略：滚动优化阶段以系统运行费用和机组启停罚金最小为目标，结合分时电价并考虑多系统互补运行，通过多步滚动求解制定系统大时间尺度调度计划；动态调整阶段以滚动优化阶段调控计划为基准，对设备的运行状...

美团研究院（陈文曦）：服务消费结构演进的国际经验与中国方向

消费既是长期趋势性变量，也是多因素交织的系统性变量。从国际经验看，居民消费结构呈现由生存型消费向发展投资型、精神享受型消费进阶的典型特征，特别是人均 GDP 超 1 万美元后，服务消费加速增长。与主要发达国家的服务消费结构相比，中国服务消费总量占 GDP 比重较低，医疗保健、餐饮住宿、休闲娱乐等领域的服务消费支出仍有一定差距。建议顺应居民消费结构演进的客观规律，强化服务消费重点领域的政策支撑，丰富餐饮、休闲娱乐等行业优质供给，促进医疗健康与其他服务业态的融合，激发民生领域的消费活力...
