An up-to-date survey of the theory of port-Hamiltonian systems is given, emphasizing novel
developments and relationships with other formalisms. Port-Hamiltonian systems theory …

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 …

Automatic generation control (AGC) regulates mechanical power generation in response to
load changes through local measurements. Its main objective is to maintain system …

This paper studies the problem of frequency regulation in power grids under unknown and
possible time-varying load changes, while minimizing the generation costs. We formulate …

We explore two different frequency control strategies to ensure stability of power networks
and achieve economic dispatch between generators and controllable loads. We first show …

In this paper, we contribute a theoretical framework that sheds a new light on the problem of
microgrid analysis and control. The starting point is an energy function comprising the …

This paper proposes a distributed sliding mode (SM) control strategy for optimal load
frequency control (OLFC) in power networks, where besides frequency regulation …

Motivated by an increase of renewable energy sources, we propose a distributed optimal
load frequency control scheme achieving frequency regulation and economic dispatch …

We augment existing generator-side primary frequency control with load-side control that
are local, ubiquitous, and continuous. The mechanisms on both the generator and the load …

This paper studies the problem of frequency regulation in inverter-based microgrids with
time-varying voltages, described by a third-order model. Building upon our previous result …
