Problems solved by technology

[0003] In the existing technology, there is no mature technical solution and engineering experience for multi-station integrated solar-storage-charge collaborative configuration. The photovoltaic, charging pile and energy storage modules generally adopt independent construction and operation methods, and the three are based on their own Capacity configuration is required; the capacity configuration of energy storage is often optimized based on a single typical daily scenario, and the configuration scheme also adopts high-capacity configuration with a large margin

Because of this, the existing technology still has the following defects: 1. The different scenarios that may occur in actual operation cannot be fully considered. The energy storage capacity is often configured too large, and the energy storage capacity cannot be fully utilized during the actual system operation. Problems that easily lead to capacity waste in the project; 2. Failure to include electric vehicle charging rules into the model for consideration
