Shanghai, Guangzhou, and other big cities.
Distributed renewable energy sources will
be mainly concentrated in remote areas and
will meet local electricity demand through
wind power and solar power.
In order to promote the development
of distributed energy, the National Energy
Board has stated that most large-scale cities
in the country will implement distributed energy
systems by 2020. At a national energy
conference in early 2010, the National Development
and Reform Commission specified
that the installed capacity of distributed
energy should reach 50 GW by 2020.
However, there are still technical, economic,
resource, and policy constraints for
distributed energy, including: lack of clear
and unified technical standards; lack of a
reasonable price system and mechanisms,
as current price systems cannot reflect energy
scarcity and environmental value; dependence
on imports of key equipment and
lack of economic advantage; and equipment
that is subject to constraints of gas supply
and pipeline network coverage. Therefore,
China should establish uniform technical
standards and develop a rational energy
price mechanism for distributed energy. In
addition, the standard management of distributed
energy should be enhanced and the
development of distributed energy should
be promoted by the approach " experiment
first, promotion later. "
Goal 5: Construct a Strong and
Smart Grid
The diverse locations of fuel supplies,
plants, and population/electrical demand
requires China to make full use of basic
functions of the grid such as long distance,
high capacity, and high energy efficiency.
During the 12th Five-Year Plan period, it is
important to accelerate the construction of
inter-provincial transmission systems and
promote the development of large bases for
coal, hydropower, nuclear power, and other
new energy resources. China can optimize
the allocation of these energy resources
by the approach of " common transmission
channel, joint development and network to
network delivery. "
A cross-regional, long-distance, and
high-capacity transmission channel connecting
China's northwestern coal base and
eastern load center regions will be built
after the layout optimization of coal-fired
power so as to achieve joint transport of
coal and wind power. Studies showed that
the development scale of wind power in Xin
Jiang, Gan Su, Meng Xi, Meng Dong, and
Ji Lin will be approximately 80 GW, 75%
of which needs to be sent inter-provincially.
Abundant solar energy resources in northwestern
areas will be developed greatly by
2020, and this inter-provincial transmission
infrastructure will allow China to expand
the development scale of wind and solar

power because it can be transmitted along
with coal power, thereby avoiding economic
problems because of isolated development
and delivery.
Northwestern coal bases and southwestern
hydropower bases have large potential
to export power. According to the analysis
of grid transmission ability, coal-fired
power flow will increase 100% from 2015
to 2020. Southwestern hydropower will be
the focus in the future, given the distribution
and development of water resources.
The outgoing capacity of hydropower from
the Jin Sha River is 13.9 GW and 30.9 GW
in 2015 and 2020, respectively, while from
Si Chuan it is 17.2 GW and 22.2 GW. The
massive pattern of " west to east " and " north
to south " will be formed by then, and the
ability of UHV and cross-transmission will
be increased dramatically.
Power development should not only follow
its own law of development but also
continue to innovate and progress. On the
supply side, the power system must not only
constantly adapt to technological advances
and large-scale development with clean and
efficient development of traditional fossil
fuel power generation but also meet the new
development requirements for hydropower,
wind power, solar power, and other renewable
energy.
On the demand side, it is necessary to
adapt technologies to meet the electricity
needs of industrialization, urbanization,
modernization, and information while
meeting green development, energy saving,
and low-carbon requirements. On the
grid side, it is essential to provide safe,
economical, clean, and efficient power
products for a modern society. Based on
an intelligent, modern, efficient information
platform and service network, a smart
grid can collect and respond to a diversified
supply side and demand side, and satisfy
the electricity needs of all.
Smart grids are developing actively
abroad. They can provide a dynamic platform
for a variety of distributed energy
resources to connect flexibly and provide
an intelligent control and management
platform to improve energy efficiency and
achieve demand side response. In addition,
a smart grid can provide an innovative application
platform for electric vehicles and
thereby help resolve issues such as power
supply security and sustainable development.
Combining the characteristics of
China's energy resource with the sustainable
development of its economy and society,
State Grid Corp. proposed strategic
objectives for a strong and smart grid.
A strong and smart grid requires an information
and communication platform
