Special Issue Information

Dear Colleagues,

The vigorous development of the renewable energy sources (RESs) strongly drives the development of green energy, green economy, and green society. Due to the inherent intermittence and randomness, however, the output power of RESs consistently experiences large power fluctuation. This non-dispatchable characteristic imposes a big challenge to interface massive renewable energy power to the power grid.

The newly emerged virtual power plant (VPP) technology is promising to turn the non-dispatchable RESs based power system into a dispatchable one. Through the integration of high performance power converters, energy storage devices, smart sensors, the cloud server, the dispatch center, etc, the RESs based power system can not only be able to perform high-efficient and high-quality voltage, current, and power regulation, but also actively interact with the power grid and support the efficient and economy operation, highly levelling up the quality of the exploitation of the RESs.

This special issue calls for the latest progress of VPP technology. The topics of interest include, but are not limited to:

  • High-efficient RES interfaced power converters
  • High-efficient grid-forming and grid-following converters
  • High-reliable energy storage technology
  • High-flexible energy management technology
  • High-performance power quality management technology
  • Smart VPP with grid-supported functions
  • Big-data assisted generation, demand, and price forcast
  • AI-assisted efficient and economic dispatch technology
  • Cyber-security management and risk mitigation
  • Health monitoring, diagnosis, and fault-tolerant operation

This paper proposes a multi-parameter estimation method based on the phase difference between primary and secondary currents, for a series/series (S/S) compensated contactless converter. To achieve secondary current sensing in the transmitter side, a primary sensing coil is added into the coupler. By introducing the phase difference between primary and secondary currents, a straightforward, multi-parameter estimation model is derived, significantly reducing the multi-parameter solving difficulty. Based on the derived model, a method combining pre-parameter identification based on frequency sweeping, with fast online parameter identification is proposed, offering a general, accurate, and rapid parameter estimation solution. Detailed implementation of the parameter identification method and the asymmetrical configuration of the coupler are also presented. The proposed method is verified with a 1 kW S/S compensated converter. Experimental results show that the estimated values agree well with the theoretical ones. Based on the estimated results, the transmitter-side, closed-loop control can also be achieved. Full article

In the last few years, there has been an exponential increase in the penetration of electric vehicles (EVs) due to their eco-friendly nature and ability to support bidirectional energy exchanges with the power cyber-physical system. However, the existing research only proposes energy management in terms of vehicle-to-grid (V2G) support using fleets of EVs, which lacks research on EV attacks. Motivated by these facts, this paper first introduces a new data integrity attack strategy for a consistent energy management algorithm which considers electric vehicles as energy storage. In particular, we consider EV aggregators as energy storage with source-charge bidirectional characteristics. The attacker carefully constructs false information to manipulate aggregators to participate in scheduling and obtaining additional benefits on the premise of meeting the constraints of microgrid and various devices by attacking the consistent algorithm. Then, we propose a disturbance rejection control strategy combining privacy protection protocols and an isolation mechanism. We analyze the effectiveness of the proposed encryption mechanism and verify the feasibility of the isolation control algorithm by simulation and comparison. Full article

In this paper, a dual-channel RF-DC microwave rectifier circuit is designed with a 2:1 power distribution ratio in a Wilkinson power splitter. The rectifier circuit works at 2.45 Ghz. After impedance matching and tuning, the structure is able to broaden the dynamic power range of the rectifier circuit while maintaining maximum rectifier efficiency. Compared with the HSMS2820 rectifier branch, this design enhances the power dynamic ranges of 60% efficiency and 50% efficiency by 4 dBm and 3 dBm, respectively. Compared with the HSMS2860 rectifier branch, for the efficiency of 60% and efficiency of 50%, the power dynamic range is expanded by 5 dBm and 2 dBm, respectively. This shows that the technology is helpful for improving the stability of energy conversion at the receiver end of microwave wireless energy transmission systems. Finally, the rationality of this conclusion is verified by establishing a mathematical model. Full article
