供需协同网络化建筑能源站互联互济鲁棒分布式运行优化

Taking building clusters as the carrier, networked building energy stations can achieve the interconnection and mutual benefits among multiple energy stations, the local consumption of renewable energy, and the integration of regional resources. Therefore, it is an important research topic to explore the road of harmonious development of energy and economy, society and environment. However, the disequilibrium problem often occurs between individual interests of energy stations and collective interests of the building cluster, due to the uncertainty of renewable energy, the supply-demand balance of multi-energy, and the complex interactive operation. As a result, some devices are over-utilized or idle, which causes a huge waste of resources and increases the operating risk of the system. To solve the above problem, this program investigates the operation of networked building energy stations from the following three research points: ① Considering the uncertain environment and operating characteristics of energy stations, we study the optimization scheduling modeling for single energy stations with supply-demand coordination under multiple uncertain disturbances. ② Based on the model obtained in ①, the multi-level robust optimization scheduling modeling of networked building energy stations is researched under a fair price mechanism for energy trade. ③ For the model obtained in ②, the robust distributed computing method is researched to realize parallel optimization of multiple energy stations. The solving of the above issues can not only enrich the theory of optimal scheduling of complex energy systems but also promote the large-scale popularization of networked building energy stations, and thus has important theoretical significance and application value.

网络化建筑能源站以建筑群为载体实现多能源站互联互济，具有可再生能源就地消纳和区域资源整合等优势，是探索能源与社会、经济、环境和谐发展道路的重要研究课题。然而，受可再生能源不确定性、能源站多能流供需平衡和多能源站复杂交互运行影响，系统运行易产生各能源站单体利益与多能源站交互运行后整体利益难以均衡的问题，导致某些设备被过度利用或闲置，造成巨大的资源浪费，增加系统运行风险。针对上述问题，本项目以网络化建筑能源站为研究对象，开展以下研究内容：①考虑不确定环境和能源站运行特征，研究一类存在多重不确定性扰动的单体能源站供需协同优化调度建模；②基于①中模型，研究能源公平交易价格机制下网络化建筑能源站多层鲁棒优化调度建模；③针对②中模型，研究鲁棒分布式计算方法实现多能源站并行优化。相关问题的解决对于丰富复杂能源系统优化调度理论，促进互联互济网络化建筑能源站大面积推广具有重要的理论意义和应用价值。
