实施例Example

结合图2,本发明提出一种基于动态电价的地源热泵系统灵活调控方法,所述方法具体为:Combined with Figure 2, the present invention proposes a flexible control method for a ground source heat pump system based on dynamic electricity prices. The method is specifically as follows:

设置地源热泵系统运行周期为24小时,并以经济性最有为目标对运行周期内每一小时的热泵系统用电负荷进行分配,进行系统灵活性调控。The operation cycle of the ground source heat pump system is set to 24 hours, and the power load of the heat pump system for each hour during the operation cycle is allocated with the most economical goal to regulate system flexibility.

起始时刻设t=0输入该灵活调控方法(调控方法基本原则为高电价时段减载降低用电负荷,减少高电价时段电费成本;低电价时段加载提高用电负荷,增加低电价时段电费成本)。Set t = 0 at the starting time to input the flexible control method (the basic principle of the control method is load shedding during high electricity price periods to reduce electricity load and reduce electricity costs during high electricity price periods; loading during low electricity price periods increases electricity load and increases electricity costs during low electricity price periods. ).

在初始运行策略中输入该时刻电网价格及运行策略算法,预测建筑冷热电用能负荷需求及热泵系统负荷率。Input the power grid price and operation strategy algorithm at that time into the initial operation strategy to predict the building's cooling, heating, and electricity energy load demand and the heat pump system load rate.

运行方法判断该时刻是否处于谷电时段,若处于谷电时段,则进一步判断热泵系统是否可调,若热泵系统可调,则调节热泵系统对电网进行取电加载提高负荷;若热泵系统不可调,则调控蓄能设备从电网取电蓄能、加载提高用电负荷;若为非谷电时段,则会进入平电时段判断程序。The operation method determines whether the moment is in the off-peak period. If it is in the off-peak period, it is further determined whether the heat pump system is adjustable. If the heat pump system is adjustable, the heat pump system is adjusted to draw power from the power grid and increase the load; if the heat pump system is not adjustable , then the energy storage equipment is controlled to take power from the grid to store energy and load it to increase the power load; if it is a non-valley period, it will enter the flat period judgment process.

运行方法判断该时刻是否处于平电时段,若处于平电时段,则进一步判断下一时刻是否处于峰值时段,若处于峰值时段,则进一步判断该时刻热泵系统是否可调(具体调控项目见表1),若热泵系统可调,则对热泵系统内各设备进行调控以增加系统从电网的取电负荷;若热泵系统不可调,则调控蓄能设备增加从电网的取电负荷;若不处于峰值时段,则不对热泵系统进行加减载控制;若不处于平电时段则会进入峰值时段判断程序。The operation method determines whether the moment is in the flat power period. If it is in the flat power period, it is further determined whether the next moment is in the peak period. If it is in the peak period, it is further determined whether the heat pump system at that moment is adjustable (see Table 1 for specific control items). ), if the heat pump system is adjustable, then regulate each device in the heat pump system to increase the system's power load from the grid; if the heat pump system is not adjustable, regulate the energy storage equipment to increase the power load from the grid; if it is not at the peak time period, the heat pump system will not be controlled to add or reduce load; if it is not in the flat power period, it will enter the peak period judgment process.

运行方法判断该时刻是否处于峰值时段,若处于峰值时段,则进一步判断该时刻热泵系统是否可调,若热泵系统可调,则对热泵系统进行调控并降低系统赢点负荷,减少对电网的取电量;若热泵系统不可调,则调控蓄能设备放能,从而降低系统从电网的取电负荷,削减电网取电峰值。The operation method determines whether the moment is in the peak period. If it is in the peak period, it is further determined whether the heat pump system is adjustable at that moment. If the heat pump system is adjustable, the heat pump system is regulated and the win point load of the system is reduced, thereby reducing the demand on the power grid. If the heat pump system is not adjustable, the energy storage equipment will be adjusted to discharge energy, thereby reducing the system's power load from the grid and reducing the grid's power peak.

在灵活调控方法中,记录了该时刻的冷热电负荷需求,机组负荷率情况基于电网发布的动态电价信息,确定热泵系统在峰、谷、平电价时刻的运行调控决策,并输出t值,若t值小于24,则继续循环该调控方法,若t值等于24,则判定该运行周期结束。In the flexible control method, the cooling, heating and electricity load demand at that moment is recorded. The unit load rate is based on the dynamic electricity price information released by the power grid. The operation control decision of the heat pump system at the peak, valley and flat electricity price moments is determined, and the t value is output. If the t value is less than 24, the control method will continue to be cycled. If the t value is equal to 24, the operation cycle will be determined to end.
