Qualification and quantification of reserves in power systems under high wind generation penetration considering demand response
(IEEE, 2015)
The presence of high levels of renewable energy resources (RES) and especially wind power production poses technical and economic challenges to system operators, which under this fact have to procure more ancillary services ...
Study of decay dynamics and CP asymmetry in D+ ? KL0 e+?e decay
(American Physical Society, 2015)
Using 2.92 fb-1 of electron-positron annihilation data collected at s=3.773 GeV with the BESIII detector, we obtain the first measurements of the absolute branching fraction B(D+?KL0e+?e)=(4.481±0.027(stat)±0.103(sys))% ...
Load-Following Reserves Procurement Considering Flexible Demand-Side Resources Under High Wind Power Penetration
(IEEE, 2015)
The variable and uncertain nature of the leading renewable energy resources, such as wind power generation, imposes the development of a sophisticated balance mechanism between supply and demand to maintain the consistency ...
Observation of a Neutral Structure near the D(D)over-bar* Mass Threshold in e(+)e(-) -> (D(D)over-bar*)(0)pi(0) at root s=4.226 and 4.257 GeV
(Amer Physical Soc., 2015)
A neutral structure in the D (D) over bar* system around the D (D) over bar* mass threshold is observed with a statistical significance greater than 10 sigma in the processes e(+)e(-) -> D+D*(-)pi(0) + c.c. and e(+)e(-) ...
Searches for isospin-violating transitions χc0,2 → π0ηc
(American Physical Society, 2015)
We present the first upper-limit measurement of the branching fractions of the isospin-violating transitions χc0,2 → π0ηc. The measurements are performed using 106×106ψ(3686) events accumulated with the BESIII detector at ...
Observation of a Neutral Charmoniumlike State Zc (4025)0 in e+e- → (D∗ D ¯ ∗)0π0
(American Physical Society, 2015)
We report a study of the process e+e-→(D∗D¯∗)0π0 using e+e- collision data samples with integrated luminosities of 1092 pb-1 at s=4.23 GeV and 826 pb-1 at s=4.26 GeV collected with the BESIII detector at the BEPCII storage ...
The determination of short circuits and grounding faults in electric power systems using time-frequency analysis
(UNIV CAPE TOWN, ENERGY RES CENTRE, 2015)
In order to ensure that electrical energy reaches consumers uninterrupted, researchers constantly try to improve power transmission lines. To realize this improvement, probable faults should be analysed through every known ...
Nano-Bioceramic Synthesis from Tropical Sea Snail Shells (Tiger Cowrie - Cypraea Tigris) with Simple Chemical Treatment
(POLISH ACAD SCIENCES INST PHYSICS, 2015)
In this study several bioceramic materials (i.e. hydroxyapatite, whitlockite) were prepared by using chemical synthesis method from sea snail shells (Tiger Cowrie - Cypraea Tigris), originated from Pacific Ocean. Maxine ...
