The load-characteristic charging of EVs and the power of distributed PVs have lately received great attention for car and electric industry due to their energy conservation and environmental friendliness. However, the disordered charging of EVs together with the distributed photovoltaic has made it challenging to meet the energy efficiency and electric quality. In an effort to overcome this challenge, the Monte Carlo method is adopted to calculate the charging load of EVs both in ordered and disordered way and the mathematical model of photovoltaic cell power is established. The reasonable dispatching in EVs and PVs is detailed demonstrated using MATLAB language, with certain day load in the area under the different circumstances. The proposed load characteristic method opens the door to research in the field of EVs and PVs, greatly enhancing the energy-using efficiency and the electric quality. © 2019 IEEE.

Radio Frequency Identification (RFID) technology has been rapidly developed in recent years. Electronic tag constitutes an important part of RFID system. This paper presents the design verification and test techniques suitable for UHF (Ultra High Frequency) RFID passive tag, which can meet the designers' demand for verification and test. Then, the IC baseband circuit test platform based on field programmable gate array is proposed. The platform can be used to verify the function of baseband circuit at design stage. It can also help designers with HDL (Hardware Description Language) code commissioning, so as to improve the reliability of circuit design, which can greatly improve the success rate of tape-out in practical applications. With regard to IC RF parameter test, this paper comes up with a low-cost test technical solution based on the commercially available card reader and the adjustable attenuator, which can be used to accurately measure the RF parameters such as IC sensitivity and input impedance without special RFID equipment, so as to guide the design of antenna and RFID. Based on the above-mentioned test scheme, the UHF RFID Tag IC that has been developed and taped out is tested in this paper. © 2019 IEEE.

In view of the lack of successful cases at domestic and abroad that closely combine the monitoring and anti-theft technology of high loss station area, the combination of line loss management and anti-theft power is not close enough, and the effect on the treatment of high loss station area is less obvious. Based on the technology of monitoring and information dynamic adaptive processing, this paper puts forward a treatment method of high loss station area. This method can realize the intelligent monitoring, early warning of the operation state of high-loss station area and the research and determination of the influence range of power theft, and develop the intelligent anti-power stealing monitoring device, which is the edge computing node, and realize the accurate identification of typical power stealing behaviors with short connection, partial voltage, shunt, zero break and equal shift under the simulation environment. © 2020 ACM.

Currently, most researches on anti-electricity stealing technologies have not combined seasonal power consumption features, social and economic information for electric stealing situational warnings, and cannot effectively solve the problem of large workload and low accuracy in manual anti-electricity stealing monitoring. In addition, they cannot provide reliable technical support for front-line staff of electricity consumption inspection and anti-electricity stealing to accurately and efficiently carry out anti-electricity stealing analysis and investigation work. In view of this situation, this paper proposes a multi-dimensional intelligent deduction and risk early warning evaluation method of electricity stealing situation. © 2020 ACM.
