| 摘要: |
| 针对产消者个体在微网间点对点能源交易中存在调节能力受限以及大规模交易可能引发网络阻塞的问题，提出一种基于能源枢纽的3层综合能源系统架构。产消者间进行能源共享，确定微网内部的能源余量或缺额；能源枢纽通过合适的价格向产消者群购买能源余量，并与其达成契约；由能源枢纽代理参与微网间的点对点交易，以实现可再生能源的进一步消纳及整体效益的最大化；针对微网间点对点交易造成的线路堵塞、潮流越限等现象，通过软开关技术进行网络重构，以保障交易行为的顺利进行。仿真算例结果表明，能源枢纽与产消者群组成的股份分红模式，使得产消者总体成本比单层交易降低42.5%，网络重构模式使交易量提高2.7%，成本降低1.5%。 |

| Abstract: |
| Aiming at the problems that the prosumer individuals have limited adjustment ability in point-to-point energy transaction between microgrids and large-scale transaction may cause network congestion, a three-layer integrated energy system architecture based on energy hub is proposed. The prosumers share the energy and determine the energy surplus or shortage within the microgrid. The energy hub purchases energy surplus from the prosumer group through appropriate price and reaches a contract with it. The energy hub agent participates in the point-to-point transaction between the microgrids to achieve further consumption of renewable energy and maximum overall benefit. Aiming at the phenomenon of line congestion and power flow over-limit caused by the point-to-point transaction between microgrids, the network reconfiguration is carried out through soft open point technology to ensure the smooth progress of transaction behavior. The simulative example results show that the share dividend mode composed of energy hub and prosumer group reduces the overall cost of prosumers by 42.5% compared with the single-layer transaction, and the network reconstruction mode increases the transaction volume by 2.7% and decreases the cost by 1.5 %. |
