Title: Plug'n'Play Operation of Microgrids: Objectives and Strategies Abstract: Motivated by the growing interest in smart grid architectures, we are interested in the problems of stabilization, power balancing, optimization, and secondary regulation in microgrids. Microgrids are low-voltage electrical distribution networks, heterogeneously composed of distributed generation, storage, load, and managed autonomously from the larger transmission network. Whereas traditional power system operation and control is hierarchical and centralized, microgrids are ad hoc networks without a centralized decision maker. These unique challenges call for scalable, robust, and plug'n'play control and optimization strategies with low (or no) communication complexity. In this seminar, we study the operation of power inverters in islanded microgrids. We discuss different decentralized primary control strategies, such as droop, quadratic droop, and virtual oscillator control. We show how these primary control strategies can achieve objectives such as power sharing, shaping of arbitrary flows, or an optimal economic dispatch. We motivate the need of additional secondary control strategies and present a distributed averaging-based controller. Finally, we illustrate our theoretic findings through simulation studies and hardware experiments.
