Performance Improvement of BPLC Based on Quantum Algorithm For New Energy Micro-grid

[摘要] The channel environment of the new energy microgrid is worse than the traditional power line. On the one hand, the grid connection and switching of a large number of energy terminals in the new energy microgrid will change the impedance characteristics of the power grid and thus affect the transmission characteristics of the power line carrier communication. At the same time, the new energy terminal grid-connected devices make extensive use of power electronic devices, making the noise of the power grid more complicated and greatly different from the noise distribution in the traditional power distribution network, which makes it difficult to detect the carrier communication signal. This article broadband PLC system uses OFDM technology as an effective way to overcome the multipath fading modulation. Although broadband powerline OFDM systems represent the direction of broadband PLC technology, the communications capabilities and quality of service currently provided by the technology are far from broadband telecommunications service standards and require further optimization.
