2019年5月13日，应威尼斯欢乐娱人城官网3328副院长阮新波教授邀请，新加坡南洋理工大学博士后徐倩雯和美国斯坦福大学博士后汪浩来威尼斯欢乐娱人城官网3328进行交流访问。当天上午9:30，在南航江宁校区电气楼学术报告厅，徐倩雯博士和汪浩博士分别做了题为“Decentralized control, stability and reliability of autonomous microgrids”和“Enabling A Smart Grid: Business Model, Machine Learning, and Algorithms”的学术报告。

徐倩雯博士针对微电网的分散控制、稳定性和可靠性展开介绍，首先介绍了一种集成在直流微网系统的混合能源储能系统及分散能源管理策略，解决了间歇性可再生能源引起的功率不平衡问题。其次，介绍了一种基于增量成本的降阶方案，实现了交流、直流和交直流混合微网系统的经济共享。随后，为了进一步提高系统稳定性，提出了一种综合非线性扰动观测器和反推算法的复合非线性技术，并针对微电网可靠性问题，介绍了一种用于微电网可靠性建模和评估的分级可靠性工具。

汪浩博士针对智能电网的业务模型、机器学习和算法展开报告。首先介绍了为了实现智能电网的无缝过渡，已经开发了各种技术，包括需求响应、可再生能源发电和能源储存。接着，介绍了上述技术给电力系统的运行和规划带来的机遇和挑战。随后，介绍了其团队在整合新设备和新技术方面提出的框架和算法相关进展。最后，讨论了一种可再生能源优化规划和运营的合作框架，该框架能够实现微电网的主动交互，并进一步讨论利用机器学习技术提高需求响应的性能和能源存储的经济可行性。

讲座过程中，徐倩文博士和汪浩博士到场师生进行了热烈讨论和深入交流。会后，徐倩雯博士和汪浩博士参观了多电飞机电气系统工信部重点实验室和江苏省新能源发电与电能变换重点实验室，就航空电力系统、微电网、高功率密度、高效率逆变器技术和电力电子可靠性研究进行了深入讨论。
