| 中文摘要: |
| 在“新能源站-电动汽车充电站-5G 基站-数据中心-变电站”五站合一的多站融合模式下，充分利用5G基站和数据中心的备用储能容量是提升多站融合经济性的重要途径。提出一种多站融合模式下共享5G基站和数据中心备用储能的多时间尺度交易机制。首先，建立了基于“储能备用时间”的5G基站和数据中心可调用储能容量模型，接着将共享储能问题转化为电量交易问题，建立了多站融合模式下内部电量交易模型，该模型可根据多站融合系统内部的交易需求，迭代更新交易价格，使各站在多度交易机制，在日前交易中通过内部电量价格交易模型进出交易出清，在日内交易中则建立了基于联络线偏差量的补偿方案。最后，通过算例验证了所提交易机制的有效性。 |

| In the multi-station integration scenario of five stations in one of“new energy station- electric vehicle charging station- 5G station- data center- substation”, making full use of the backup energy storage capacity of 5G base station and data center is an important way to improve the economy of multi-station integration. A multi-time scale trading mechanism for sharing the backup energy storage capacity of 5G base stations and data center under the multi-station integration mode is proposed. Firstly, 5G base station and data center call energy storage capacity model based on the“energy storage spare time”is set up, and then the shared energy storage problem is transformed into electricity trade problem to established the internal power price trading model, which can dynamically adjust the power price, make more station system internal trading more economical according to the internal power trading demand. Then, a multi-time scale trading mechanism of pre-day declaration- day adjustment is established. In the day- daytrade, the electricity trade are cleared through the internal electricity price trading model, and a compensation scheme based on the deviation of the contact line is established in the intra-day trading.Finally, the validity of the proposed trading mechanism is verified by example. |
