Abstract
本发明涉及火力发电与新型储能技术领域，提供了一种与主再热系统深度耦合的熔盐‑相变‑电化学三级协同火电调峰系统及控制方法，所述系统：熔盐储热子系统，用于从火电机组的多路热源吸收热量进行长时储热，并向火电机组的蒸汽侧和 / 或外部供热管网释热；相变材料储热子系统，用于为从火电机组的蒸汽侧或给水侧吸收热量进行中短时储热，并向锅炉释热；电化学储能子系统，用于与火电机组的电气侧连接；中央协同控制系统，用于根据电网工况和机组运行状态执行分级时序协同控制。本方案不仅实现了深度调峰、快速爬坡、AGC调频及100%热电解耦等目标，且无需对机组本体进行大规模改造，可以兼容新建与在役机组，提升了工程适用性。
