[0121] 结合以上描述的关于上层控制和下层控制两种控制模型或策略,本发明上下层整体调度的思路如下: [0121] connection with the above described control on the upper layer and the lower layer or the control of two control policy model, according to the present invention, the idea underlying the entire schedule is as follows:

[0122] 上层调度的目标是:在保证园区安全稳定的前提下,实现自身的投资、运行费用最小。 Target [0122] The upper scheduler is: in the park to ensure the security and stability of the premise, to achieve their own investment, minimum operating costs. 当用户负荷出现较大增加时,上层调度增加发电机、直调储能出力,可调节用户进行削峰,保证关口功率不越限。 When the user loads a larger increase, increase upper scheduler generator, directly modulated output storage, user clipping can be adjusted to ensure that the power does not pass the threshold. 在要求互动用户进行用户减少负荷削峰,需满足对不同互动用户参与需求响应的补偿电价最小。 The user interaction required to reduce the load clipping user, the minimum required to meet the needs of different user interaction participation response compensation price.

[0126] 阶段三:用户负荷增加很大,园区发电机、直调储能无法平抑负荷的增加,关口功率越限,影响园区内电网的安全稳定,且单纯通过可调节用户可以平抑负荷波动。 [0126] Phase III: user load increases greatly, the park generators, energy storage can not be directly modulated to stabilize the load increases, the more limited power juncture, affect the security and stability of the power grid in the park, and can be adjusted simply by the user can stabilize the load fluctuations. 上层园区调度对下层可中断用户下发指令,互动用户对自身负荷进行合理中断,根据指令参与调峰, 达到功率平衡,实现电网的稳定。 Send the upper park schedule at the lower interruptible user instruction, interactive user to load their own reasonable interruption, peaking participation according to the instructions, to achieve power balance, stable power grid.
