一种适用于变频压缩机组的光伏储能协同补冷控制方法及系统

本发明涉及一种适用于变频压缩机组的光伏储能协同补冷控制方法及系统，PLC获取光伏实时功率、储能电池SOC、冷藏空间温度、相变蓄冷单元温度及压缩机状态，调用预先标定的压缩机功率—频率关系，计算电池允许补差功率和压缩机可用功率；根据相变温度平台、温度变化率及累计有效制冷量确定蓄冷状态，生成主制冷请求或光伏补冷请求，并选择可用功率所允许的目标运行频率。当光伏功率下降时，依次执行电池限功率补差、持续不足确认后的降频以及最低频率下的停机；安全保护停机优先于最小运行时间，正常再次启动受最小停机间隔限制。本发明使压缩机运行功率与光伏、储能及蓄冷需求相匹配，减少光伏波动造成的频繁启停，提高光伏就地利用率和蓄冷控制可靠性。
