In wind and solar energy, both regular and contract workers

Real work.

The original China Wind Power was mainly engaged in the investment and operation of wind and solar power generation, as well as the power generation service business. wind and solar energy. You can apply for it if you have a university degree and. you will be a full-time employee after joining.

Concord New Energy Group Co., Ltd., formerly China Wind Power Group Co., Ltd., is a group company specializing in wind power generation.

Which is cheaper, wind power or photovoltaic power generation

Wind power and photovoltaic power are new energy sources that China is focusing on. The electricity network must absorb them fully and. use them first. Hydroelectricity also requires priority use of the electricity network during periods of flooding. It is aboutt comprehensive consideration of a series of factors such as environmental protection and the reduction of carbon emissions. The electricity network can therefore do nothing! Why is it called “junk electricity”? There are mainly two aspects.

First, photovoltaic and wind power have low installed capacity and are scattered, making it difficult to meet the peak load regulation needs of the power grid! To put it simply, when the weather is sunny and the wind is blowing, the insufficient thermal power will be supplemented. When short-term electricity demand increases rapidly, photovoltaic and wind power cannot meet it. On cloudy days and when there is no wind, the power plant is dead. When there is a shortage of electricity, it is only thermal energy! And the price of new electricity on the network is relatively high! Thatmeans that when the sun rises, the heat load decreases and when the sun sets, the heat load increases. For the power grid, constant adjustments are required, which is not conducive to the safety and economical operation of the power grid. Secondly, wind and photovoltaic power are not stable enough, resulting in the transmission of harmonics to the power grid system, which will increase power losses and affect motor efficiency, which will affect the manufacturing of high precision ! These two reasons should be the reason why photovoltaic power and wind power are called "trash energy".

Both are new energy production, which are currently being promoted and vigorously developed by the state, and there are huge state subsidies. , the grid settlement price for thermal power is about 0.3 yuan per kilowatt hour,and the price of wind and photovoltaic power generation ranges from 0.3 to 0.8 yuan.

Both types of electricity generation had a fatal flaw at the time, namely their intermittency. Solar power produced electricity during the day and could not produce electricity at night. Wind power could produce electricity when it was windy. but it would not be able to produce electricity in the absence of wind. These two types of power generation are actually not well received by the power grid, but due to state support for new energy and requirements for energy saving and emission reduction, the electricity network company must accept them unconditionally.

There are more and more of these two types of electricity production, which lead to instability in the electricity network. Currently we rely primarily on clippingthermal energy peaks, pumped energy storage, wind energy heating and wind energy heating. building energy storage power plants to solve intermittent problems. At the same time, wind and solar energy forecasts are becoming more accurate, which also reduces pressure on electricity grid regulation.

Why can't we build solar power plants in the desert?

Which is cheaper: wind power generation or photovoltaic power generation? Wind power is low, wind power costs about 4-5 yuan per watt, and photovoltaic power costs about 7-8 yuan per watt. Low-light photovoltaic panels are cheaper. As photovoltaic power generation technology, particularly photovoltaic panels, continues to mature, the applicaphotovoltaic energy production continues to develop. Photovoltaic power generation is also an emerging industry with good prospects.

Photovoltaic energy production equipment takes up less space and is also suitable for use in cities. To be useful, wind energy production equipment must be located in a location subject to relatively strong winds. These locations must be far from large cities.

The advantages and disadvantages Photovoltaic energy production:

1. Advantages of photovoltaic power generation

Compared with commonly used thermal power generation systems, the advantages of photovoltaic power generation are mainly reflected in:

② Safe and reliable, no noise, no emissionslluent, absolutely clean (no pollution

③ Not limited by the geographical distribution of resources); the advantages of building roofs can be used; for example, areas without electricity and areas with complex terrain;

④Can generate electricity and provide electricity on site without consuming fuel or erecting transmission lines;

⑥It is easy for users to accept it emotionally;

⑦The construction period is short, and the time required to obtain energy is short.

2. Disadvantages of photovoltaic power generation

① The energy distribution density of irradiation is low, that is, it occupies a huge area

② The energy obtained is the same as that of the four seasons, day and night, and it is related to weather conditions such as cloudy and sunny conditions.

③ TOAt present, compared to thermal energy production, the cost of electricity production is high.

④The manufacturing process of photovoltaic panels is not environmentally friendly.

As the world develops new energies and expands wind and solar power, research has shown that solar farms can have unintended consequences on the environment , notably global warming. or even trigger more precipitation, causing systemic impacts on the global climate.

Deserts with flat lands, sparse population and abundant sunshine have always been the first choice for solar power plants. The world's ten largest solar power plants are all located in deserts or arid areas. .

Key benefits:

Scientists from Sweden's Lund University and Western Sydney University ebelieve that it is possible to transform the largest desert in the world into a huge solar farm capable of producing enough electricity to meet current needs. global energy needs 4 times higher. Solar power plants planned in Tunisia and Morocco can now meet the electricity needs of millions of homes in Europe. But scientists worry that although solar panels can absorb most of the sunlight, only about 15 to 20 percent of the incident energy is converted into electrical energy.
