In this paper we consider a linear system structured into physically coupled subsystems and propose a decentralized control scheme capable to guarantee asymptotic stability and satisfaction of constraints on system inputs and states. The design procedure i ...
The dynamics of power system blackouts and the associated Self-Organized Criticality (SOC) behavior is a subject that receives continuous attention in view of its inherent complexity and relevant consequences. Within this context, the paper focuses on the ...
Sound absorption can be achieved in a relatively simple manner with passive or active electroacoustic absorbers. Electroacoustic absorbers are basically loudspeakers, the membrane of which is used as an absorber/reflector of sound, and the electric termina ...
Both deterministic and probabilistic approaches can be used to establish spinning reserve requirements. It has been proved that determining reserve requirements based on probabilistic approaches results in more economical efficiency. So, a probabilistic se ...
This paper discusses strategies for the environomic optimization of renewable energy conversion technologies that are at the conceptual process design stage and produce multiple energy services, using Life Cycle Assessment (LCA). It is illustrated by an ap ...
Microfabricated fuel cell systems have the potential to outperform batteries for man-portable power generation. Because many electronic devices operate at various loads, with frequent start-ups and shut-downs, transient aspects are highly important and mus ...
In this dissertation, I determine the strategic options of energy service companies active in urban areas. This work is developed considering the wider EU policy framework, namely a liberalised energy market, environmental protection and security of supply ...
This paper addresses issues concerning the integration of single-phase charging devices for electric vehicles (EV) in low-voltage microgrids Fast release energy storage is a key issue for microgrid islanding operation. EV batteries provide an additional st ...
This paper presents a method for optimal sizing and operation of a battery energy storage system (BESS) used for spinning reserve in a small isolated power system. Numerical simulations are performed on a load-frequency control (LFC) dynamic simulator of t ...
More "green" power provided by Distributed Generation will enter into the European electricity network in the near future. hi order to control the powerflow and to ensure proper and secure operation of this future grid, with an increased level of the renew ...
