In this paper cyber role in social-ecological energy systems SEES is formalized by using the language of large-scale dynamical systems. The key notion of interaction variables is introduced in support of their modeling as multilayered dynamical systems. It is stressed that qualitatively different cyber designs are required for enabling performance of qualitatively different SEES architectures. In particular, it is proposed that composite control-based hierarchical control lends itself more naturally to supporting large-scale regulated monopolies, and that distributed multi-layered control with or without coordination is key to supporting SEES architectures comprising many decision makers. Today's hierarchical control is described as a particular case of hierarchical composite control. Having these formulations may help bridge R&D efforts across vastly multi-disciplinary communities working in the field of changing electric energy systems.
Topics considered include characteristics of power generation units, transmission losses, generation with limited energy supply, control of generation, and power system security. This book is a graduate-level text in electric power engineering as regards to planning, operating, and controlling large scale power generation and transmission systems. Material used was generated in the post-1966 period. Many (if not most) of the chapter problems require a digital computer. A background in steady-state power circuit analysis is required.
In this paper we study the controllability of the Keller-Segel system approximating its parabolic-elliptic version. We show that this parabolic system is locally uniform controllable around a constant solution of the parabolic-elliptic system when the control is acting on the component of the chemical.
