Probability constrained optimisation model for transmission expansion planning considering the curtailment of wind power

open access: yesThe Journal of Engineering, 2019
The curtailment of wind power has caused huge economic losses and needs to be considered on the stage of transmission expansion planning (TEP). Based on the superquantile theory, the authors use the buffered failure probability to handle the events of ...

Weierstrass and Approximation Theory

open access: yesJournal of Approximation Theory, 2000
This is a lovely article on Weierstrass and the early development of approximation theory. It begins with a short biography of Weierstrass. Two main themes stand out in his work: To set a new standard of rigor in analysis, and his love for power series or more generally for function series.

Rough analysis in lattices. [PDF]

open access: yes
An outline of an algebraie generalization of the rough set theory is presented in the paper. It is shown that the majority of the basic concepts of this theory has an immediate algebraic generalization, and that some rough set facts are true in general ...

Simplified LLR algorithm for m-QAM demodulation

open access: yesThe Journal of Engineering, 2019
Here, a simplified algorithm to calculate log-likelihood ratio (LLR) for m-QAM demodulation is proposed. Traditional method calculating LLR for m-QAM demodulation is supposed to do distance computing between any two constellation points so that the high ...

Automated scheme for linearisation points selection in TPWL method applied to non-linear circuits

open access: yesThe Journal of Engineering, 2019
Trajectory piecewise linear (TPWL) approximation is a well-known model order reduction technique for non-linear systems. It involves weighted summation of the dimensionally reduced linear systems obtained at certain points on the system trajectory.

Distributed equalisation strategy for multi-battery energy storage systems

open access: yesThe Journal of Engineering, 2019
Multi-battery energy storage systems (MBESSs) are widely adopted to overcome the uncertainty problem of renewable energy sources. However, state-of-charge (SOC) imbalance issue of MBESSs brings great challenges to the optimal dispatching strategy and the
