Recent years, the popularity of wind power and the widely use of diversified loads have increased the uncertainty of power systems in both supply and demand sides. This paper develops a multi-time scale unit commitment optimization model under wind power and future load uncertainties. First, dayahead wind power and electric load forecast is obtained by long short-term memory network, based on which the on/off status and first-period output of units are determined. Then rolling economic dispatch is applied when real time data is collected from the system. To solve the above unit commitment and economic dispatch model, an improved particle swarm optimization algorithm is proposed. Finally, several experiment were performed to demonstrate the effectiveness of this research.

In this paper, a new mode-dependent average dwell time (MDADT) stability result of discrete-time switched systems with all subsystems unstable is investigated. Combined with MDADT analysis method, we classified subsystems into two categories: switching stable subsystems and switching unstable subsystems. State divergence caused by switching unstable subsystems could be compensated by activating switching stable subsystems for a sufficiently long time. Based on the above considerations, a new globally exponentially stability result was proposed for switched systems with all subsystems unstable. In addition, the new result is a generalization of the previous method, which is more suitable for the case of more unstable subsystems. Some numerical examples are given to illustrate the advantages of our established results.

A 3.75-4.25GHz frequency modulated continuous wave (FMCW) radar transceiver, employing intermediate-frequency (IF) delay rather than RF beat frequency to represent distance, is implemented in 65nm CMOS for applications in ultra-wideband (UWB) band. To overcome the trade-off between wide bandwidth and high ranging resolution in the conventional FMCW radars, a dual-BPF regenerative FM demodulator and a time-to-digital converter (TDC) are utilized to achieve low power, low complexity, and fine ranging resolution. In the transmitter, a slew rate controlled relaxation oscillator and a 3-stage RF voltage-controlled oscillator (VCO) are hired to perform frequency modulation with significant power savings. In addition, a successive approximation register (SAR) logic based automatic frequency calibration (AFC) loop is placed in the transmitter to calibrate the frequencies of the oscillators for process, voltage and temperature (PVT) robustness consideration. The proposed transceiver with 3.3mW power consumption and −110dBm sensitivity, features sub-cm ranging capability, better than the conventional designs with tens of centimeters resolution.

This paper proposes a connected area algorithm for processing a line of pixels collected by linearity CCD camera at a time based on FPGA. It can be used in material sorting equipment to separate materials of different sizes. The method is based on the twice scan method of the connected area, and implemented on FPGA, called two-row scan method. It needs to save only two rows of pixels and it is only one pixel in every scan unit. Because of scanning two rows of pixels every time, the real-time performance is extremely excellent. After calculating the area of the connected area, it will be selected and removed according to the upper limit and the lower limit while the location of the material is determined by the channel division algorithm and the high speed air valve. The area error calculated by this method is less than 5%, and the material elimination rate can reach more than 90%.

Corona discharge on transmission lines is a common phenomenon in power systems. Long-time continuous corona discharge on lines may cause serious grid accidents. It is of great significance to effectively locate the corona discharge point. The Hilbert fractal antenna is a wide-band, small-sized antenna through which an electromagnetic wave signal generated by corona discharge can be detected. In this paper, a 5th order Hilbert fractal antenna is designed focusing on the different feeding modes of the antenna. Then the miniaturized antenna structure that can be used for corona discharge detection of transmission lines is determined.

Data transmission between spacecraft and Earth-based data receiving stations is one of the vitally important subsystem for any space mission. The time interval of visibility between spacecraft and ground stations is most valuable to accomplish scheduled data transmission volume. An algorithm to enable the more effective space-based antenna during data transmission process is put forward and analyzed in detail in this paper. A series of detailed phases are formulated, which helps space mission software engineers to easily code the smart algorithm and carry out code-testing conveniently. Once this algorithm is realized in a space mission, it could help to enhance the smartness of onboard computer software and minimize the manned intervention on the ground, which meets the current demands of artificial intelligence in space.

With the increasing number of users and the complexity of services, only single communications network cannot meet its request in smart distribution grid(SDG).Therefore, heterogeneous network is an effective way to solve this situation. In this paper, a new approach of heterogeneous wireless network for SDG based on the chi-square distance is proposed and investigated. The algorithm firstly estimate weights of network attributes using analytic hierarchy process(AHP) according to different types of service which depends more on the consideration for the user side. Secondly, the CRITIC and anti-entropy weighting method are used to determine the objective weight according to the actual network parameters, and the final weight is obtained by the comprehensive weighting method based on the alignment minimization. Finally measure the chi-square distance from each candidate network to the ideal network, and the candidate network of smallest chi-square distance is the best access network.

Internet of Things (IoT) plays a significant role in facilitating our work and making ease the life of human, for the reason that it can connect a lot of embedded devices to deal with many complicated and difficult tasks. However, security of IoT is more concern because every device is connected through internet network, and eavesdroppers are ready to steal or even uncover our private data. Therefore, in this paper, we propose joint single relay and jammer selection (JSRJS) to enhance the physical layer security (PLS) of IoT. Moreover, outage probability (OP) and intercept probability (IP) as well as the system tradeoff performance (STP) for JSRJS under Nakagami-m fading channel are analyzed, and OP、IP as well as STP of JSRJS are all compared with that of the pure single relay selection (SRS), respectively. Simulation results show that the OP of JSRJS is the same as that of SRS, while the IP of JSRJS is always better than that of SRS. In addition, the STP for JSRJS is also more perfect than that of SRS. Besides, as the number of relay nodes increases, the STP of these two approaches both improve notably.
物联网(Internet of Things, IoT)可以连接大量的嵌入式设备来处理许多复杂和困难的任务，它在方便我们的工作和简化人类的生活方面发挥着重要作用。然而，物联网的安全性更受关注，因为每个设备都是通过互联网连接的，窃听者随时准备窃取甚至泄露我们的私人数据。因此，在本文中，我们提出联合单中继和干扰器选择(JSRJS)来增强物联网的物理层安全性(PLS)。分析了JSRJS在Nakagami-m衰落信道下的中断概率(OP)、截获概率(IP)和系统权衡性能(STP)，并将JSRJS的OP、IP和STP分别与纯单中继选择(SRS)进行了比较。仿真结果表明，JSRJS的OP与SRS相同，而IP总是优于SRS。此外，JSRJS的STP也比SRS的STP更完善。此外，随着中继节点数量的增加，两种方法的STP性能都有显著提高。

This paper proposes a configurable structure of time-interleaved ADC (TI-ADC) with digital blind calibration for time-variant input signal. The channel number of the TI-ADC and the corresponding digital calibration could adapt to the input frequency, which would significantly decrease the power consumption of the TI-ADC as well as reduce the complexity of the digital calibration. In the proposed structure, the input signal is firstly fed into the power detector to roughly determine the range of the input frequency. Then the TI-ADC system activates the required sub-ADC channels accordingly and the calibration module changes to adapt to the input signal. In addition, numerical simulations have been presented to demonstrate the effectiveness and superiority of the proposed structure, which shows the proposed structure could significantly decrease the power consumption of the TI-ADC module as well as the calibration module.
