MCU standby power management promotes low-carbon application design

During the transmission of electricity, at least 10% of the electricity is wasted. In order to save energy, energy is now continuously produced in a "healthy" way. However, as long as it is transmitted using the traditional power system, this unnecessary waste cannot be avoided.

According to the forecast of the US Energy Information Administration, from 2005 to 2030, the annual power generation of developed countries will increase by 1-3%, while that of poor countries will increase even faster, with an average annual increase of 4%. The old power grid system obviously does not meet the requirements of an ecological society. In such a context, smart grids are beginning to be favored by more and more countries.

In the construction of smart grid system, the most important thing is to introduce "smart meters", which can record the real-time electricity consumption and transmit the information back to the power company. In recent years, as the cost of smart meters has become lower and lower, the idea of ​​their widespread installation in ordinary households has become possible.

People can generate energy through solar devices. In addition to using it for their own homes, they can also generate excess energy and sell it back to the power system. They can also monitor the power consumption of home appliances in real time through iPhones, and reduce power consumption during peak hours.

According to statistics from ABI Research, there are 76 million smart meters installed worldwide, and this number is expected to grow to 155 million in 2013. In this regard, Enel, the largest energy company in Italy, is at the forefront. Since 2001, Enel has installed more than 30 million smart meters for its users.

With the continuous improvement of living standards and the continuous development of science and technology, people's functional requirements for "smart meters" will not stop at basic functions such as prepayment, accurate measurement, and data statistics. They are more looking forward to the emergence of highly intelligent "electricity meters" so that power companies can adjust at any time according to the demand and supply of electricity. Compared with the power company's method of large-scale power outages, this adjustment method is obviously more reasonable.

This is both a golden opportunity and a huge challenge for instrumentation companies. It can be said that the electric energy meter industry has entered a new development space.
