REF630 As the name suggests, DC microgrid is a power system that transfers electrical energy by DC, connects DC load and DC power supply through DC cable, and directly uses DC energy. It can effectively integrate distributed energy, energy storage system, load and other resources to improve the efficiency of power system operation.
Especially in the industrial field, the advantages of supplying power to industrial equipment through DC microgrids are more obvious.
Help to reduce power input, save energy, reduce carbon emissions;
Reduce cable usage;
Increase grid stability;
When used as infrastructure to intelligently control energy flows, it can also enhance the advantages of energy procurement;
Support modular concept
To this end, not only domestic and foreign enterprises have increased resREF630 earch and development investment, seeking technological innovation and breakthroughs, our government has also issued a series of policies to encourage DC microgrid technology research and development and demonstration application, to create favorable conditions for the development of the industry. At present, DC microgrid has been put into use in residential, commercial, industrial and other fields, and its market scale continues to expand. It is predicted that in the next few years, China’s DC microgrid market will continue to maintain rapid growth.
The development prospect of DC microgrid is self-evident, but there are still many challenges in its construction and practical use.
First of all, the construction and use of DC microgrid involves many fields, and the technology is complex, and customers have difficulties in selection, design, operation and maintenance.
Secondly, the DC microgrid system has a high voltage, and once a failure occurs, it is very likely to lead to safety accidents.
In addition, the problem of equipment compatibility is also an important factor limiting the development of DC microgrid, DC microgrid equipment is a wide variety, the compatibility between different brands, models is poor, greatly affecting the stability of the system.
Challenge is the opportunity, face the challenge, with advanced technology and mature solutions to empower the development of DC microgrid industry promising. Weidmuller, an electrical connection expert who has been deeply involved in DC technology for many years, is well aware of this and is actively involved in the research projects REF630 of the industry benchmarking associations DKE and DC-INDUSTRIe as a member and is committed to developing innovative solutions. So what efforts has WeidMuller made in the process of promoting the development of the DC microgrid industry, and what solutions can be provided to users to build a reliable, efficient and unbreakable DC microgrid?
