摘要：

储热装置的热特性分析是实现电?热联供系统中电、热综合调度的关键之一。针对含储热的电?热联供系统,应用能量流法构建包含储热、传热和漏热过程在内的系统整体能量流模型,获得系统中电能、热能的整体传输约束。并且,以最小化系统总运行成本为优化目标,分析储热装置热特性对运行成本和风电消纳的影响。结果表明:增强储热性能(储热介质最高温度或装置总体积)、传热性能(循环水最大质量流量、换热器面积)和隔热性能(隔热材料厚度),均可不同程度地促进风电消纳,降低总运行成本。其中,增加储热介质的温度上限和传热装置的总体积可使循环水的平均质量流量分别降低15.3%和17.4%,并且存在最佳的换热器面积和循环水流量上限使得总运行成本最低,可为制定含储热电?热联供系统的综合调度方案提供依据。
