The key to developing energy storage lies in the advancement of battery
technology
Recently, at the "2018 Smart Energy Development Summit Forum" hosted by the
China Electricity Council, participating representatives conducted in-depth
discussions on hot topics such as "Internet +" smart energy, regional energy
transformation, comprehensive energy services, and energy storage technology
trends. .
Microgrid is an important component of smart grid
"Looking at today's energy development, the traditional era of single power
generation and single transmission is gone forever. We have fully opened the era
of 'Internet +' smart energy." Fei Zhi, President of GCL Smart Energy Co., Ltd.,
believes that the new era has great influence on energy. Development has put
forward the requirements of cleanliness, intelligence, efficiency, safety and
reliability. With the large-scale application of renewable energy and the
continuous maturity of information technologies such as the Internet and the
Internet of Things, vigorously developing the energy Internet has become an
irreversible trend. It has also become an era proposition that global new energy
companies urgently need to explore and actively respond to.
Microgrids are considered by the industry to be an important part of the
energy Internet. According to experts, as a new energy network supply and
management technology, the energy of microgrids is not strictly defined, ranging
from tens of kilowatts to tens of megawatts. Its role is to coordinate the
originally dispersed distributed power sources with each other to ensure the
reliability and security of the distribution network. At the same time, it can
smoothly connect to the renewable energy system and realize user demand side
management and existing energy and resources. of maximum utilization.
Compared with traditional power grids, the biggest feature of microgrids is
that they can digest and balance distributed energy on-site, and can also
exchange energy with large power grids. For this reason, microgrids are
considered an important part of the smart grid field and have broad application
prospects in industrial and commercial areas, urban areas, and remote areas.
“In the long run, the development of microgrids is very important. In the
foreseeable future, with the advancement of distributed renewable energy storage
microgrid technology, cost reduction, and the emergence of new loads, combined
with the reform of the electricity sales side, microgrids will There will be an
increasing share of the electricity market," said Tang Xuewen, director of the
New Energy Division of the Jiangsu Provincial Energy Bureau.
However, some industry experts said that microgrid research is currently in
the ascendant, especially in terms of raw materials, components, components,
system software networks, etc. that are the basis of the industry. There are
still many topics that require in-depth research.

technology
Energy storage technology is considered the “last mile” of new energy
development. The so-called energy storage is to store secondary energy through
chemical or physical methods to realize the transfer of energy in time and
space. Experts said that the reason for developing energy storage is because
energy storage meets people's needs for portable and mobile equipment in
production and life.
At present, my country's new energy development momentum is very rapid.
According to the plan, the installed capacity of wind power and photovoltaic
will reach 1 billion kilowatts in 2050. However, along with the development of
new energy, the phenomenon of wind and light abandonment is very serious. The
reason is that new energy power generation is unstable and intermittent, and
large-scale development and utilization will make the contradiction between
supply and demand more prominent. In a sense, the degree of application of
energy storage technology will determine the development level of new
energy.
