In recent years, there are some studies that report the method to levitate and manipulate a particle using ultrasonic waves. In the conventional acoustic levitation method using the compact acoustic delay-lines device, however, it was so difficult to pick up a particle located on the stage. In this research, we examine a new approach to make it possible to pick up a particle located on the stage combining simple ultrasonic transducers array and effective stages.

Glass is widely used as an optical material due to its high transparency, thermal stability, and mechanical properties. The ability to fabricate and sculpt glass at the nanoscale would naturally expand its application domain in nanophotonics. Here, we report an approach to print glass in three dimensions with nanoscale resolutions. We developed Glass-Nano, an organic-inorganic hybrid resin containing silicon elements. Using this high-resolution resin, three-dimensional (3D) photonic crystals (PhCs) were printed with two-photon lithography. After printing, the structures were heated to high temperatures in air to remove organic components and convert the remaining material into silica glass. 3D glass PhCs with periodicities as small as 260 nanometers were obtained after sintering at 650°C. The 3D glass PhCs exhibit ~100% reflectance in the visible range, surpassing the typical reflectances observed from similar structures in low-refractive index materials. The quality of PhCs achieved is observed in both electron microscopy and the excellent agreement with band structure calculations of idealized structures.

The future smart grid entails clusters with plug-and-play features known as microgrids. Each microgrid hosts a mix of distributed energy resources including synchronous-based. Nevertheless, synchronous-based generators, are characterised by their limited reactive power capabilities which could lead to voltage collapse problem during islanding. Microgrids also comprises controllable loads. The majority of modern loads are power-electronic-interfaced and demand voltage regulation at their ends, exhibiting constant power characteristics. Microgrids with high penetrations of constant-power loads are vulnerable to voltage collapse especially during contingencies such as weather-caused outages. To this end, this paper investigates the possibility voltage collapse phenomenon in islanded microgrids during contingencies. The voltage stability analysis was carried out on an islanded 6-bus microgrid. Several case studies were designed in order to reveal the likelihood of voltage collapse in microgrids under extreme events. © 2018 IEEE.

Coordinated Optimal Control of Constrained DERs

Coordinated Optimal Control of Constrained DERs

Control Technology and Applications (CCTA),

作者： Roland Harvey Zhihua Qu Toru Namerikawa Department of Electrical and Computer Engineering University of Central Florida Orlando USA Department of System Design Engineering Keio University Japan

In this paper, a coordinated optimal control is designed to simultaneously satisfy multiple power system objectives at the distribution network level. With high penetration of renewables, traditional generation and control may not be enough to compensate for intermittent changes in net load. Dynamic coordination of battery storage devices and demand response at aggregated distributed energy resource (DER) sites becomes necessary to maintain power system operation, however, each dynamic power component operates at different time scales. Frequency stabilization can be achieved by designing optimal controls for traditional generation, storage devices and demand response. The proposed optimal controls naturally render frequency separation of these load balancing mechanisms. Given a 24-hour net load forecast, optimal tracking control inputs are designed subject to constraints of selected system elements to ensure optimal performance of the power system. Simulation results are presented and discussed.

—This paper presents a semantic brain computer interface (BCI) agent with particle swarm optimization (PSO) based on a Fuzzy Markup Language (FML) for Go learning and prediction applications. Additionally, we also establish an Open Go Darkforest (OGD) cloud platform with Facebook AI research (FAIR) open source Darkforest and ELF OpenGo AI bots. The Japanese robot Palro will simultaneously predict the move advantage in the board game Go to the Go players for reference or learning. The proposed semantic BCI agent operates efficiently by the human-based BCI data from their brain waves and machine-based game data from the prediction of the OGD cloud platform for optimizing the parameters between humans and machines. Experimental results show that the proposed human and smart machine co-learning mechanism performs favorably. We hope to provide students with a better online learning environment, combining different kinds of handheld devices, robots, or computer equipment, to achieve a desired and intellectual learning goal in the future.

Passivity-Short-based Stability Analysis on Electricity Market Trading system Considering Negative Price

Control Technology and Applications (CCTA),

作者： Keita Muto Toru Namerikawa Zhihua Qu Department of System Design Engineering Keio University Yokohama Kanagawa Japan Department of Electrical and Computer Engineering University of Central Florida Orlando FL USA

This paper deals with a distributed decision method for determining the electricity price considering the negative price in the market trading. In addition, we analyze the stability and convergence properties for the market trading system using the concept of passivity-short. At first, mathematical models of market participants' behavior which maximize their own profits are discussed. Then, we construct a trading system based on dynamic pricing considering plug and play operation that each market participant intermittently participates in market trading. As for the optimal electricity price, even if the optimal price might be negative, we indicate the stability of the system can be guaranteed by using passivity-short which is a relaxed concept of passivity. Finally, numerical simulation results illustrate that each value decided by the market trading converges to the optimal value.
