Figure PCTCN2021110074-appb-000011
最优化综合调控系统获取天气预报信息以及一体化系统的当前储能信息，基于能量平衡公式及其限制条件(具体参见实施例二)进行寻优运算，对目标函数求出最优解(即功率配比数据)，将最优解对应的控制指令推送至数据总线，储能前端的DC/DC变换器根据经总线推送的功率控制数据控制电储能的实时能量流向，光伏变流器根据经总线推送的功率控制数据控制压缩机系统及变流器内部的AC/DC模块、DC/AC模块，实现市网、压缩机、蓄冷储能间的能量流向控制。
在一些实施例中，在收到天气预报信息的0时刻，最优化综合调控系统根据此时刻的电储能部件、蓄冷储能部件推送到总线上的当前储能信息P A(n)(t)和c A(n)(t)，各个子系统的功率、能量平衡，在限制条件下，对目标函数
Figure PCTCN2021110074-appb-000012
进行寻优运算，得出最优能量流动配置下的p A(n+1)(t)、c A(n+1)(t)在0→τ时间段内的储能状态以及各个时刻的p(t)、p M(t)、p S(t)、p SP(t)、c(t)、c S(t)、c M(t)，并将运算结果推送至系统内数据总线。

系统正常工作的某一时刻，当c S(t)＞0时，蓄冷储能部件处于蓄冷状态，此时光伏变流器输出控制信号控制电控阀K1、K3状态为开，由于压缩机处于运行状态，因此冷冻水泵J1也处于开启状态，此时有两种状态，状态1：若空调末端所需的制冷功率c(t)＝0，则电控阀K2和主水泵J2不开，参考图6，此时冷冻水管路内的水流流向为：蒸发器594→K1→蓄冷储能部件(图中未示出)→K3→J1→蒸发器594；状态2：若c(t)＞0时，此时电控阀K2和主水泵J2处于开启状态，且各水泵配套变频器控制水泵使得主水泵流量小于冷冻水泵流量，参考图6，此时冷冻水管路内的水流流向包括：蓄冷流向和压缩机向末端供冷流向，其中，蓄冷流向为：蒸发器594→K1→蓄冷储能部件(图中未示出)→K3→J1→蒸发器594，压缩机向末端供冷流向为：蒸发器594→K1→K2→空调末端57→J2→J1→蒸发器594。
当c S(t)＝0时，蓄冷储能部件暂停蓄冷和放冷，此时电控阀K3关闭，有两种状态，状态1：若c(t)＝0，则电控阀K1、K2、冷冻水泵J1和主水泵J2均不开，水流管路内的水流冷冻水停止流动；状态2：若c(t)＞0时，此时电控阀K1、K2、主水泵J2和冷冻水泵J1处于开启状态，且各水泵配套变频器控制水泵使得主水泵流量等于冷冻水泵流量，参考 图6，此时冷冻水管路内的水流流向为：蒸发器594→K1→K2→空调末端57→J2→J1→蒸发器594。
当c S(t)＜0时，蓄冷储能部件处于放冷状态，此时有两种状态，状态1：当c M(t)＝0时，此时空调末端所需冷量全部由蓄冷储能部件提供，此时冷冻水泵J1和电控阀K1关闭，电控阀K2、K3、主水泵J2开启，参考图6，此时冷冻水管路内的水流流向为：蓄冷储能部件→K2→空调末端57→J2→K3→蓄冷储能部件；状态2：当c M(t)＞0时，此时由压缩机和蓄冷储能部件联合向空调末端供冷，电控阀K1、K2、K3、主水泵J2、冷冻水泵J1均处于开启状态，且各水泵配套变频器控制水泵使得主水泵流量大于冷冻水泵流量，参考图6，此时冷冻水管路内水流方向包括：压缩机向末端供冷流向和蓄冷储能部件向末端供冷流向，其中，压缩机向末端供冷流向为：蒸发器594→K1→K2→空调末端57→J2→J1→蒸发器594；蓄冷储能部件向末端供冷流向为：蓄冷储能部件→K2→空调末端57→J2→K3→蓄冷储能部件。
