摘要
High penetration of distributed energy resources is transforming the paradigm in power system operation. The ability to provide electricity to customers while the main grid is disrupted has introduced the concept of microgrids (mu Gs) with many challenges and opportunities. Emergency control of dangerous transients caused by the transition between the grid-connected and island modes in mu Gs is one of the main challenges in this context. To address this challenge, this paper proposes a comprehensive optimization and real-time control framework for maintaining the frequency stability of multi-mu networks under an islanding event and for achieving optimal load shedding and network topology control with ac power flow constraints. This paper also develops a strong mixed-integer second-order cone programming based reformulation and a cutting plane algorithm for scalable computation. We believe, this is the first time in the literature that such a framework for multi-mu G network control is proposed, and its effectiveness is demonstrated with extensive numerical experiments.
