Peak shaving applications provided by energy storage systems enhance the utilization of existing grid infrastructure to accommodate increased penetration renewable sources. This work investigates provision peak services from a flywheel system installed in transformer substation. A lexicographic optimization scheme is formulated define power set-points minimizing limit violations and losses. Con...

As the key mechanism of attitude control micro/nano-satellites, flywheel design is mostly based on empirical formulae that do not meet requirements lightweight and high-performance micro/nano-satellite platforms. In this paper, structural shape flywheels analysed, a set optimisation methods proposed to realise parametric analysis shape. First, general principle efficiency introduced, evaluation...

Reciprocating compressors are most common type of compressor and most flexible machine to handle wide capacity and condition swings. They offer a most efficient method of gas compressing. They are vital machines in various units of industrial plants. In this paper advanced technologies and latest configurations and methods regarding condition monitoring, performance, flow management, capacity c...

Abstract Concerns over global warming and the need to reduce carbon emissions have prompted development of novel energy recovery systems. During urban driving, a significant amount is lost due continuous braking, which can be recovered stored. The flywheel storage system efficiently recover store vehicle's kinetic during deceleration. In this study, Computational Fluid Dynamics (CFD) model was ...
