Description

Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to a prefabricated energy storage module for a photovoltaic-storage-diesel microgrid. Background Technology

[0002] Conventional prefabricated energy storage systems employ multiple energy storage battery clusters connected in parallel, with the output connected to a centralized energy storage converter, and then connected to the power grid via an isolation transformer, operating in a peak-shaving and valley-filling mode. The main drawbacks of this system are as follows:

[0003] 1. Limitations of parallel connection of battery clusters:

[0004] Because the battery clusters are directly connected in parallel, the overall lifespan of the system may be limited by the battery with the shortest lifespan, a phenomenon known as the "weakest link" effect. Circulating currents may arise between parallel battery clusters due to inconsistent depths of discharge, which not only affects the system's charging and discharging efficiency but may also lead to overcharging of the cells, increasing safety risks.

[0005] 2. Challenges of centralized energy storage converters:

[0006] Although the control logic of centralized energy storage systems is simple, once a fault occurs, on-site debugging is complex and time-consuming, usually requiring professional personnel from the manufacturer to come to the site for maintenance, resulting in long system downtime and high operation and maintenance costs.

[0007] 3. The difficulty of implementing peak shaving and valley filling strategies:

[0008] The implementation of peak shaving and valley filling strategies is technically challenging. These strategies rely on advanced technologies such as energy storage systems, smart meters, and remote monitoring, all of which are costly to develop, deploy, and maintain. Changing user habits is also difficult, as peak shaving and valley filling strategies require users to alter their traditional electricity consumption habits, potentially impacting their daily lives and work. This necessitates a high degree of cooperation and self-discipline from users. Furthermore, the implementation of peak shaving and valley filling strategies may pose risks to the safe operation of the power grid, such as voltage fluctuations and harmonic pollution.
