Combined With The New Deal, Analyze The Development Of Microgrid Technology And Test Solutions
2021-11-25
In recent years, my country's coal and other conventional energy sources have been seriously in short supply, and environmental problems such as air pollution caused by coal burning have also become increasingly serious. The energy problems and environmental problems caused by the power system characterized by a centralized and single Power Supply method have attracted more and more attention from the society. With the development and utilization of new energy and the development of smart grid technology, a new form of grid structure-smart microgrid has emerged, which is the mainstream direction of future grid development. The concept of "carbon neutrality" has changed from "avant-garde" to "mass", and the optical storage market has also ushered in a new round of overall development of the industry. The single string inverter has reached the power level of 300kW. In response to the increasing test needs of the photovoltaic industry, APM provides more complete test solutions for photovoltaic inverters, photovoltaic simulators, and microgrid systems. In this live broadcast, APM technical experts will combine the market prospects of microgrids and related policies to interpret related test technologies and solutions in the microgrid field (including grid-connected inverters, energy storage converters, and new energy vehicles). 1. Basic composition and typical structure of microgrid The development of microgrid technology is closely related to advanced power electronics technology, computer control technology, and communication technology. In all microgrid systems, the basic component is the power source. The power supply must meet the load requirements in the microgrid, such as capacity, and other technical and economic considerations. Among them, distributed photovoltaics have received widespread attention. In particular, the decline in the price of photovoltaic cell modules in recent years has increased the economic feasibility of distributed photovoltaic-based microgrids. 2. Analyze the development prospects of the industry in combination with favorable policies Carbon peaking and carbon neutrality have become hot topics at home and abroad, and will surely become an important force to promote the rapid development of the energy storage industry. There are more and more battery companies, photovoltaic companies, power equipment companies, and large energy groups. According to the special needs of microgrid, it is necessary to study the power electronic technology used and develop a series of new power electronic equipment. 3.
