Functional PCS power supply system with EV battery storage for stable PV power delivery

This research proposes a residential Photovoltaic-Power Conditioning Subsystem (PV-PCS) in a functional and stable power supply system with battery storage (Electric Vehicle [EV] storage etc.) to reduce PV output fluctuation. In PV power generation, PV power fluctuations caused by weather changes make it difficult to obtain stable power output. Further, it can then be expected that this adversely affects the power system. In this paper, functional power supply system model is constructed with power fluctuation suppression control system using bidirectional DC/DC converter and existing residential PCS and EV battery storage. Furthermore, simulation results of the electric battery power suppression element of the PV power fluctuation are also shown by using Simple Moving Average (SMA) control method to suppress PV power fluctuation. PV power suppression system using existing residential PCS has an advantage that can not only suppress the energy change during normal operation but can also construct the isolated power supply in an emergency case of power supply loss. In this emergency case, EV battery storage control provides the power to critical loads during utility outage. This feature is not available without storage. Also, effectiveness of PV-PCS interconnection stable power supply system with existing residential PCS in Japan was proposed. Moreover, a basic research of solar power generation amount of solar radiation estimation and the resulting simulation on information acquisition method of solar energy capacity using Geographic Information System (GIS) are presented

Isolation and phototransformation of enantiomerically pure iridium(iii) bis[(4,6-difluorophenyl)pyridinato-N,C2]picolinate

Here we report the resolution of phosphorescent light-emitting iridium(III) bis[(4,6-difluorophenyl)pyridinato-N,C2]-picolinate into its respective enantiomers by using chiral HPLC and the photo-induced transformation of the isolated enantiomers

Formation of supramolecular hetero-triads by controlling the hydrogen bonding of conjugate bases with a diprotonated porphyrin based on electrostatic interaction

The thermodynamic stability of diprotonated saddle-distorted dodecaphenylporphyrin (H4DPP2+(X−)2) was controlled by the hydrogen-bonding strength of conjugate bases (X−) of strong acids (HX) or acids (R+-COOH) having positively charged moieties. The thermodynamic control of H4DPP2+(X−)2 made it possible to achieve selective formation of supramolecular hetero-triads, H4DPP2+(X−)(Cl−)

Formation and Isolation of a Four-Electron-Reduced Porphyrin Derivative by Reduction of a Stable 20π Isophlorin

The two‐electron reduction of a diprotonated dodecaphenylporphyrin derivative by Na2S2O4 gave a corresponding isophlorin (Iph) selectively. Formation of Iph was confirmed by spectroscopic measurements and the isolation of tetramethylated Iph. Further reduction of Iph proceeded to form an unprecedented four‐electron‐reduced porphyrin (IphH2), which was fully characterized by spectroscopic and X‐ray crystallographic analysis. IphH2, with a unique conformation, could be oxidized to reproduce the starting porphyrin, resulting in a proton‐coupled four‐electron reversible redox system

Fundamental electron-transfer and proton-coupled electron-transfer properties of Ru(iv)-oxo complexes

Isolation and characterisation of Ru-IV(O) complexes were accomplished to investigate their fundamental electron transfer (ET) and proton-coupled ET (PCET) properties. Reorganisation energies (lambda) in electron transfer (ET) and proton-coupled ET (PCET) from electron donors to the isolated Ru-IV(O) complexes have been determined for the first time to be in the range of 1.70-1.88 eV (ET) and 1.20-1.26 eV (PCET). It was suggested that the reduction of the lambda values of PCET in comparison with those of ET should be due to the smaller structural change in PCET than that in ET on the basis of DFT calculations on 1 and 1e(-)-reduced 1 in the absence and presence of TFA, respectively. In addition, the smaller lambda values for the Ru-IV(O) complexes than those reported for Fe-IV(O) and Mn-IV(O) complexes should be due to the lack of participation of d(sigma) orbitals in the ET and PCET reactions. This is the first example to evaluate fundamental ET and PCET properties of Ru-IV(O) complexes leading to further understanding of their reactivity in oxidation reactions
