First, we want
to discuss why renewable energy system is so significant. The world is facing a
phenomenal defining moment. Environmental change addresses a genuine and
impending danger to the success that many appreciate today, and that millions
try to and are running after. It is more than this. It is about the endurance
of the most defenseless of this planet's residents, and regarding the insurance
of biological systems and biodiversity that we ought to protect. The changing
environment is generally being driven by emanations from consuming
non-renewable energy sources, although there are other significant supporters.
To stem environmental change we should lessen our utilization of these
carbon-concentrated fills. Renewables can and should be a focal piece of this
arrangement.
Energy
system for the happiness
Once upon a
time, there was a mountain, and there was a room in the mountain. In the room,
there was a Xiaoming who was waiting for the dawn.
"I
heard that the power line was broken by the storm..." Xiao Ming was lying
at the window, listening to the wind outside and thinking, "It seems that
the finale of the cartoon tonight will not catch up... Depressed."
"Electricity
belongs to human beings. My good friend, I can't live without it." On this
night, Xiao Ming once again deeply felt the importance of electricity.
I have to say,
Xiao Ming is the truth. Since the first application of electricity in our
lives, we can't live without it. And now, if there is a sudden power outage
somewhere, there must be dozens or hundreds of Xiaoming sitting in front of the
window waiting for dawn.
So, how can we
make it easy for everyone to use green, safe and stable electricity? The
engineers were also heartbroken. Finally, they developed Distributed Energy
Systems (DES) to solve these problems.

A little more How did the electricity come from?
At present, the basic mode of power supply in most parts of the world is a
centralized power supply. Electricity is produced from a large centralized
power plant "on the other side of the mountain, on the other side of the
sea", and passes through the high-voltage transmission line over the
mountains to the substation, where it is depressurized and then reaches thousands
of households through the local distribution network. How far can a centralized
power plant be from our home? The world's first 1100kV HVDC transmission line
built by Siemens Energy can transmit the power generated in Chongjin, Xinjiang
to Guquan, Anhui, which is 3,300 kilometers away. The distributed energy system
is the complete opposite of this traditional model. It uses distributed power
generation. This model is not unique in recent years. In early 1879, Siemens
Energy received an order for "lighting equipment" from the Qing
government. Siemens Energy provided a 10-horsepower steam generator for
lighting in Shanghai Port, which greatly improved the port's work efficiency.
Hundreds of years later, the modern distributed generation is still close to users
and has become more advanced and intelligent. Now, people can not only use
natural gas to generate electricity but also comprehensively use renewable
energy such as solar energy, wind energy, biomass, etc., to continuously
produce electricity in a more efficient and environmentally friendly way. The
organic combination of distributed power generation equipment and corresponding
energy management solutions forms the simplest distributed energy system unit.
Let me explain this concept seriously and seriously: distributed energy system
is a small or micro-independent energy source that uses natural gas, biomass
energy, solar energy, wind energy, and other renewable clean energy as a
primary energy, at or near the user's site. A system that outputs electrical and
thermal (cold) energy. It can be tailored to the specific needs of users, such
as reducing energy costs, improving energy efficiency, ensuring power supply
stability, and reducing carbon emissions. Generally speaking, in a simple
distributed energy system unit, the power generated by the power generation
equipment can directly reach the consumer end through the distribution network,
which can be said to be very direct and convenient!

Invisible "Command"
However,
everyone knows that renewable energy sources like solar and wind are volatile.
For example, if the sky is clear today, photovoltaic power generation will be
leveraged. But if it is rainy and rainy, then it is a bit powerless to want
solar power generation. You may say, then I will install several different
types of power generation devices in the area. If solar power cannot be used,
wind power will be used. If wind power does not work, biomass power will be
used. Isn’t that good? This is indeed a good approach, but if these different
power generation units are directly connected to the distribution network
through different coupling points, not only will the main grid be subjected to
considerable shocks, but the various power generation units will not be able to
coordinate with each other.
Therefore, to
better manage various distributed power generation resources in the region or
manage multiple energy systems at once, so that everyone can use electricity
happily every moment, the magical microgrid was born. The combination of
distributed generation equipment, energy storage equipment, loads, and energy
management solutions including microgrid management technology forms a
microgrid energy system. A microgrid acts as a "guide" for each
generation resource or system in a region. In the face of "willful"
different types of energy, the microgrid can use digital technology and
cooperate with energy storage equipment to complete the dispatch and control of
cooling, heating, and electricity, and finally achieve a balance between energy
supply, energy storage, and energy demand. In this way, an internally balanced
energy system can be connected to the main grid through a single coupling
point, avoiding shocks to the main grid.
Combined with
energy management technology, the operation mode of the microgrid is also very
flexible. According to the needs of users, it can either be connected to the
main grid or run independently off the grid. When connected to the main grid,
it can deliver power to the main grid with insufficient power, and can also
obtain excess power from the main grid with sufficient power. And when it is
disconnected from the mains grid, it operates in island mode. In island mode,
microgrids can provide power to areas far from the main grid, such as
mountainous areas.
Distributed
energy systems have quietly entered our daily life. Whether it is commercial
buildings such as office buildings, hotels, supermarkets, public places such as
schools, hospitals, and amusement parks, or industrial parks, residential
areas, rural areas, military bases, etc., they are the main application
scenarios of distributed energy systems. The distributed energy system can be
very close to you, right by your side, supporting every little happiness
brought to you by electricity.

Four
important advantages
So, where is the
distributed energy system good? Today, we will take Xiao Ming's life as an
example to tell you about the four main advantages of distributed energy
systems.
First of all,
the basic operation mode of the distributed energy system is "self-use,
and the surplus power is connected to the Internet". For example, in Xiao
Ming's house, it used to be the model of "use electricity - pay
electricity bill - use electricity", but now it's different! If Xiao
Ming's community uses a distributed energy system, then they can use the
electricity generated by the community itself. And, if more electricity is
being generated today, some of that electricity can be sold to the grid. In
this way, the user's electricity cost will be lower, isn't it beautiful?
Secondly, the
residential area can get more than electricity after using the distributed
energy system. Since the distributed energy system adopts cogeneration in power
generation, the heat generated by the gas turbine unit can be reused by the
steam turbine unit, and after being used for two rounds, the remaining heat can
also be used for heating and cooling. It is equivalent to the triple supply of
cold, heating, and power, and it kills three birds with one stone. Isn't it
great!
In addition,
remember the little Ming who was lying at the window waiting for the dawn at
the beginning of the article? With the distributed energy system, watching the
finale of the cartoon at night is all right. Since the distributed energy
system is deployed near the user, the influence of bad weather on long-distance
power transmission is avoided, and it is safe and reliable. If the power
consumption side adopts the energy model of the distributed energy system and
the main grid, then once the main grid fails, the microgrid can immediately
disconnect from the main grid and use its power supply to restore power.
Knowing this knowledge.
Finally,
distributed energy systems are very environmentally friendly due to the use of
clean or renewable energy when generating electricity. As a good boy who loves
the earth and is committed to controlling carbon emissions, Xiao Ming expressed
his satisfaction and gave alike.

RENEWABLE ENERGY TECHNOLOGY COST REDUCTIONS
The subject ought not to be "How
environmentally friendly power can be cutthroat", because environmentally
friendly power advances are now serious. The inquiries should be how we would
drive down costs considerably further and what are the difficulties looked in
accomplishing that objective.
