Compared with narrowband power carrier (PLC) technology, broadband power carrier technology has advantages in stability, transmission efficiency, data security, networking capabilities, etc. It is an emerging power carrier technology that has only been commercialized in recent years. It is also the main bearing technology of the smart grid in the future. According to the data, smart meters currently have a global installed ratio of about 6%. By 2016, North America will replace 45% of its electricity meters with smart meters, and the EU will install 80% of smart meters by 2020.
It is estimated that between 2012 and 2016, the number of newly installed smart meters will reach 475 million.
According to the development plan of “Strong Smart Grid†built by China State Grid Corporation: 2009-2010 is the pilot stage of strong smart grid planning; from 2011 to 2015 is the comprehensive construction stage to accelerate the construction of UHV grid and urban and rural distribution network; 2016 From 2020 to 2020, a unified "strong smart grid" will be built. Among them, it is estimated that between 2012 and 2016, China will install 170 million smart meters, nearly 50 million smart meters will use broadband PLC technology, and the period of rapid growth of China's broadband PLC market will soon come. , declined to reprint).
“The United States, China, and South Korea are indeed countries that are moving faster on the smart grid.†Yang Naihua, senior manager of business development at Marvell, told the EE Times reporter, “While broadband PLC is a new technology, there are many imaginations in its application model. In September 2010, Marvell entered the PLC field by acquiring DS2, a Spanish-based power communication IC design vendor. Its smart grid solutions include semiconductor chips, firmware, software platforms, hardware reference designs and evaluation tools.
At the “Strong Smart Grid 2011 Summit Forum†held in Beijing recently, Taiwan Shengda Electric Co., Ltd. (Billion) demonstrated the energy management solution for electric vehicle charging stations developed by Marvell smart grid technology. It includes: a prepaid electric meter (Billion SG3150-P) and a smart card reader (Billion SG3150-CR). Through Billion's Unified Monitoring Infrastructure (UMI), power usage information is transmitted to the power company's central control management center to remotely manage and monitor power usage status. When the electric vehicle needs to be recharged, the driver can drive the car to the parking lot with the charging device, and charge the pre-charged card (the electronic engineering album copyright is declined).
