TL;DR: A delay-free-based distributed algorithm is presented to optimally assign the whole energy demand among local generation units with the objective of minimizing the agminated operation cost by implementing the proposed algorithm.
Abstract: This paper investigates the economic dispatch problem of microgrids in a distributed fashion. To address this issue, a delay-free-based distributed algorithm is presented to optimally assign the whole energy demand among local generation units with the objective of minimizing the agminated operation cost. By implementing the proposed algorithm, each component can find its own optimal operations by only requiring local computation and communication. As a result, it enhances the system robustness, flexibility, privacy, etc. More importantly, the time-varying delays model is considered and embedded into the design of our distributed algorithm, such that the components can employ the delays information to achieve the collaborative operation, which are more general and applicable for practical power systems. In addition, we have proved that the proposed algorithm can converge to the global optimal point under some sufficient conditions. Finally, several simulations are provided to demonstrate the correctness and effectiveness of the proposed algorithm.

TL;DR: The influence of pyrolysis temperature on capacitive performance of hetero-atom (oxygen and nitrogen) doped carbons derived from polypyrrole nanowire arrays is investigated and it is revealed that the concentration ofhetero-atoms as well as the ratio of electrical double layer capacitance and pseudo-capacitance can be tuned by varying the pyrolynsis temperature.
Abstract: Heteroatom-doped carbonaceous materials derived from polymers are emerging as a new class of promising supercapacitor electrodes. These electrodes have both electrical double layer capacitance (from carbon matrices) and pseudo-capacitance (from hetero-atoms). Balancing the electrical double layer capacitance and pseudo-capacitance is a key to achieve large capacitance at ultrafast current densities. Here we investigate the influence of pyrolysis temperature on capacitive performance of hetero-atom (oxygen and nitrogen) doped carbons derived from polypyrrole nanowire arrays. Structural and electrochemical characterization reveal that the concentration of hetero-atoms as well as the ratio of electrical double layer capacitance and pseudo-capacitance can be tuned by varying the pyrolysis temperature. In fact the hetero-atom doped carbon sample obtained at a relatively lower pyrolysis temperature (500 °C) exhibits the optimal capacitive performance. It yields an outstanding areal capacitance of 324 mF cm−2 at 1 mA cm−2 (141 F g−1@0.43 A g−1), and more importantly, retains an areal capacitance of 184.7 mF cm−2 (80.3 F g−1@43.5 A g−1) at an ultrahigh current density of 100 mA cm−2. An asymmetric supercapacitor consisting of hetero-atom doped carbon as an anode delivers a maximum volumetric energy density of 1.7 mW h cm−3 at a volumetric power density of 0.014 W cm−3, which is among the best values reported for asymmetric supercapacitors.

TL;DR: In this paper, an Al-Mg-Sc alloy with an approximately random misorientation distribution and predominantly high-angle boundaries of 97% was produced by friction stir processing and achieved a ductility of 235% at 200 degrees C. Increasing temperature from 200 to 300 degrees C resulted in an increase in superplasticity, optimum strain rate and strain rate sensitivity.

TL;DR: In this article, the (N, S and C) co-doped TiO2 samples (NSC-TiO2) were synthesized by the sol-gel method combining with the high energy ball milling method calcined at the different temperature (400-700°C), employing butyl titanate as the titanium source and thiourea as the doping agent.
