To handle the challenges attributed to distributed generators, protection system of distribution networks needs be evolved. Recent schemes modify standard characteristics overcurrent relays, called non-standard characteristics. These are mostly case-dependent and have limitations in solving variety generators. This paper analyses performance six voltage-based on photovoltaic generators (PVDG) p...

This study introduces a quadratic programming-based optimisation method to coordinate electric vehicle (EV) charging and photovoltaic (PV) curtailment in unbalanced low voltage (LV) networks. The proposed model is defined as convex that guarantees the optimal global solution of problem avoiding complexity non-linear models surpassing limitations local solutions derived from meta-heuristics algo...

The structure of a dioctahedral 2M2 mica was defined by high voltage electron diffraction. The cell parameters are: a = 8-965, b ~ 5-175, c = 20.31 A, fl = 100 ~ 40', Z = 4, space group C2/c. Despite the peculiar character of the layer dispogition (or 4 as ~r~ as) , the oxygens of the layers are packed according to the cubic law. Consequently, the interlayer cations K have a trigonal prismatic ...

Manganese hexacyanoferrate (Mn-PBA) is a promising cathode material for sodium-ion secondary battery (SIB) with high average voltage (=3.4 V) against Na. Here, we find that the thermal decomposition of glucose modifies the surface state of Mn-PBA, without affecting the bulk crystal structure. The glucose treatment significantly improves the rate properties of Mn-PBA in SIB. The critical dischar...

This aim of this study was to investigate an unexpected finding from a larger study examining the play of preschool children with and without developmental coordination disorder (DCD). We found that children with DCD were more frequently involved in aggressive incidents during free-play than their peers. Children with (n=32) and without DCD (n=31) were videotaped during free-play at preschool a...

Children (10 or 11 years old) with and without developmental coordination disorder (DCD) were exposed to imposed optic flow in a moving room. We manipulated the amplitude and frequency of oscillatory room motion, and we evaluated the coupling of standing body sway with room oscillations. The results revealed that standing sway of both children with and without DCD was influenced by room motion....

The stability of single and bimanual (i.e., in-phase and antiphase) rhythmic finger movements was studied in 24 children with a developmental coordination disorder (DCD) and 24 matched controls from a dynamic pattern perspective. Stability was assessed by applying perturbations and measuring the time the system needed to return to its initial stability (i.e., the relaxation time). In addition, ...

This paper suggests an approach of synchronized and incorporated management of solar power PV generators with the maximum power point tracking (MPPT) management and battery power storage space management to offer 1)voltage and frequency (V-F) support to an islanded microgrid 2) real and reactive power (P-Q) support during grid connection. The present novel control strategy show the the effectiv...
