In recent years, due to the wide utilization of direct current (DC) power sources, such as
solar photovoltaic (PV), fuel cells, different DC loads, high-level integration of different …

Historically, centrally computed algorithms have been the primary means of power system
optimization and control. With increasing penetrations of distributed energy resources …

Modeled after the hierarchical control architecture of power transmission systems, a layering
of primary, secondary, and tertiary control has become the standard operation paradigm for …

This paper considers distribution networks featuring inverter-interfaced distributed energy
resources, and develops distributed feedback controllers that continuously drive the inverter …

Future power networks are expected to incorporate a large number of distributed energy
resources, which introduce randomness and fluctuations as well as fast control capabilities …

Mathematical optimization is one of the cornerstones of modern engineering research and
practice. Yet, throughout all application domains, mathematical optimization is, for the most …

This paper develops and analyzes feedback-based online optimization methods to regulate
the output of a linear time invariant (LTI) dynamical system to the optimal solution of a time …

Automatic generation control (AGC) is primarily responsible for ensuring the smooth and
efficient operation of an electric power system. The main goal of AGC is to keep the …

In this article, a novel distributed secondary control scheme is proposed to solve the voltage
regulation and power sharing problems of an islanded direct current (DC) microgrid. It not …

Frequency control rebalances supply and demand while maintaining the network state
within operational margins. It is implemented using fast ram** reserves that are expensive …
