Research on Expansion Capability Evaluation of Multi-Station Integration Considering Internal and External Collaborative Matching

Multi-station integration is an important way to carry out function reuse in substations, which can revitalize the superior resources of substations and expand emerging businesses of power grid companies. This paper presents an evaluation method for the expansion capability of substations. This paper firstly investigates the resource requirements of data center stations, energy storage stations, charging and swapping stations, distributed photovoltaic stations, 5G base stations, and Beidou ground reference stations from the perspectives of space, power, and communication. Then, the evaluation index and evaluation method of resources in substation are proposed. Finally, with an example of a substation, three possible expansion capability schemes are listed.
