摘　　要：在当前“双碳”背景下,许多企业都在探索用户侧分布式新能源的应用。本研究集光、储、用等诸多元素于一体,搭建起工商业用户侧分布式新能源智能微网。截至目前,微网经过5年时间的实际运行,验证了谷电峰用、需求侧容量管理、需求响应等多种微网模式,理想条件下单独运行年收益分别达到24.88万元、26.40万元、32.88万元,并探索了多模式协调运行策略。运行数据统计表明:利用分布式新能源以及储能系统构建的智能微网,在主控系统的协调控制下,实现了工商业用户侧百分百的绿色能源供应,实现了碳中和目标,通过微网多模式协调运行,年收益可达52.29万元,远超其他单一运行模式收益,为分布式新能源智能微网的应用和推广起到了一定的示范和参考作用。Numerous businesses are investigating the industrial and commercial consumer side application of distributed new energy against the backdrop of “carbon peaking and carbon neutrality.” In this project, a smart microgrid with distributed new energies on the industrial and commercial user side has been built, which incorporates many components,including photovoltaics, vanadium energy storage systems, and industrial loads. The microgrid has been active for 5 years, and several microgrid operational modes have been confirmed,such as peak shaving, demand-side capacity management, demand response, etc. Under perfect circumstances, the yearly income of independent operation will generate ￥248810(peak shaving), ￥264000(demand-side capacity management), and ￥328800(demand response), respectively. Also, a multimode coordinated operation technique has been investigated.Operational data figures show that the smart microgrid built using distributed new energy and energy storage systems achieved a 100% green energy supply on the industrial and commercial user side while being controlled by the primary control system, thereby achieving carbon neutrality targets. Additionally, the annual income of the microgrid can generate up to ￥522, 886, which is significantly more than the income of conventional single operation modes. It contributes to the application and promotion of distributed new energy smart microgrids in several ways by serving as a demonstration.
