摘要(Abstract)：

针对新能源存在不稳定性导致电网调峰问题日益严重的现状，结合较为成熟的光煤互补发电技术及多热源联合供热调峰系统，设计光煤混合供热发电系统，使热电联产机组具有一定的调峰能力。以某300 MW热电联产机组为研究对象，利用Ebsilon Professional软件搭建发电、供热可灵活调节的太阳能辅助热电联产系统，基于供热机组实际双机运行工况，在保证供热负荷前提下，分析太阳能辅助双机热电联产机组耦合方式，比较耦合前后双机调峰性能。结果表明：凝汽器出口与太阳能集热系统换热器间的管道上设置动态节流阀，改变太阳能集热系统辅助供热机组的运行模式，能够实现发电、供热、调峰一体系统的灵活运行；其中，以太阳能集热系统仅用于补充供暖的运行方式调峰能力最强，太阳能辅助单机供热前后调峰容量比值为0.76，太阳能辅助双机供热前后调峰容量比值为0.55，太阳能辅助承担最大供热负荷的1号机组在调峰容量及调峰补偿上效果最佳。
