[0018] Such as figure 1 As shown, a microgrid optimal scheduling method, including:

[0019] S1. According to the environmental characteristics of the location of the micro-grid system and the characteristics of historical electricity consumption habits, configure the micro-grid system with the configuration scheme with the highest comprehensive benefit; first select the configuration scheme of the micro-grid system that can adapt to the characteristics of the local environment, and then choose among them that can meet the requirements The configuration plan of the characteristics of historical electricity consumption habits, and finally adopt the multi-group differential evolution algorithm to optimize the calculation to obtain the configuration plan with the highest comprehensive benefit;

[0020] S2. Realize the collection of working condition parameters of each power generation sub-system in the micro-grid system based on the working condition acquisition module mounted on...

Embodiment 2

[0024] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that, in this embodiment, the following steps are also included:

[0025] S4. Based on the current working condition parameters of each of the power generating subsystems, perform real-time working condition assessment for each of the power generating subsystems, and output a fine-tuning plan based on the joint scheduling scheme and the result of working condition assessment; when the result of the working condition assessment falls When the preset fault threshold is entered, the steps of starting the early warning plan include: starting the SMS automatic editing module to send the result of the working condition evaluation to the maintenance personnel terminal;

[0026] Carrying out a real-time environmental assessment of each of the power generation subsystems based on the current environmental parameters of the location of each of the power generation subsystems, and when the resul...

Embodiment 3

[0028] Such as image 3 As shown, the difference between this embodiment and Embodiment 2 is that, in this embodiment, the following steps are also included:

[0029] S5. Based on the data mining module, realize the summary registration of all executed scheduling schemes and the public data of each power generation subsystem in the microgrid system between the two scheduling schemes in the form of an EXCEL table, so as to realize the traceability of all scheduling schemes.

[0030] This embodiment fully considers the local environmental parameters, electricity consumption habit parameters, and the working condition parameters of the microgrid system itself, which can well avoid the blindness of the scheduling scheme, so that the microgrid scheduling scheme is more in line with actual needs and realizes the greatest value. The method of joint scheduling is adopted, so that the advantages of different power generation sub-systems under different weather conditions can be used to...
