OREANDA-NEWS.  June 06, 2013. After CCTV Oriental Horizon broadcasted the series report on “Approaching New State-owned Enterprises”, starting by featuring SGGCC on May 21th, the CCTV News’ 4-minite-16-second-long headline news“SGCC: Accommodate New Energy and Facilitate Green Development” once again opened the series report “Approaching New State-owned Enterprises”.

On the same day, CCTV Live News ran a report on “Eyes on EU’s Anti-dumping and Anti-subsidy Investigation Against Chinese Solar Manufacturers; Distributed Power or to Save PV Industry”, which introduced that SGCC released the Guideline on Integration Service for Distributed Power to support the national policy and help with a rapid development of the distributed PV generation. The report mentioned that SGCC not only came up with a solution for on-grid power generated by individuals, but also boost a sustainable development of China’s PV industry.

These two reports demonstrate the company’s efforts in UHV and S&T innovation, which enables the national power grid to accommodate the largest capacity of clean energy in the world, and boost a rapid growth of new energies, such as wind power and PV generation. They also publicize SGCC’s route of changing the energy development mode by transforming the grid development mode, which in return, promotes the economic development transformation. SGCC’s core values “Integrity, commitment, innovation and dedication” are underlined. The company has established a favorable image of a responsible central SOE.

While the global competition is getting fiercer, China’s economy is at a transforming and upgrading phase. As an important pillar of the national economy, what new directions and achievements do state-owned enterprises (SOEs) have to improve their innovative capability and optimize the industrial layout? CCTV News is now launching a series report on “Approaching New State-owned Enterprises” today. First, let’s take a look at SGCC and its actions on accommodating new energy and promoting a green development.

SOEs are the important pillar of the national economy and a major force to realize the “Chinese Dream”. What new directions and achievements do state-owned enterprises (SOEs) have to improve their innovative capability and optimize the industrial layout? CCTV News is now launching a series report on “Approaching New State-owned Enterprises” today.

China’s installed capacity of thermal power accounts for 94% of the total electricity. Such an energy structure ensures us a rapid economic growth but also costs us a good environment. How to make electricity cleaner and more environmental friendly? SGCC is turning this objective into reality by constantly innovating in S&T.

Western China is endowed with rich coal resources and abundant clean energies, such as wind power, hydropower, and solar power. SGCC’s scientific and technological innovations one after another can turn these low-carbon energies into electricity and integrate them into the power grid in large capacity.

Reporter Chen Yan: “Now we are in Zhangbei County in Hebei Province. It is the world’s largest smart system to accommodate new energy stably, integrating wind power generation, PV generation, power storage and smart transmission. Its stable operation demonstrates that China’s power grid is technically capable of accommodating large-capacity clean energy.”

Big winds result in large capacity of electricity while small winds bring none. A cloudy day has no yield in solar power generation. The instability in wind and solar power can cause the fluctuation in the power grid once these new energies are integrated. The National Wind/PV/Energy Storage and Transmission Joint Demonstration Project, with a total investment of 9.4 billion yuan, is built to solve this problem. It combines wind power, PV power and power storage, collocates them so that they can be as stable as thermal power, and then integrates them into the main grid.

The deputy director of production technology department Niu Hu said: “Blue represents wind power, which is unstable. Green means PV generation, which is also unstable or even worse. Now after the adjustment from the smart stable integration system, you see this yellow line. It’s very stable, close to the curve of the conventional thermal power.”

The project’s general manager Gao Mingjie said: “These technology is an effective way out to integrate new energies.”

During the system’s operation in 18 months, it has integrated 400GWh of clean energy accumulatively. In mid May, its phase-2 project was launched. The clean energy integration technology will appear in more new energy bases in the future. As of the end of April, the integrated installed capacity of new energy such as wind power in China exceeded 60GW.

Now electricity can be on grid but it also needs to be transmitted out. Trans-regional long-distance transmission cannot be neglected.

SGCC spokesperson Zhang Zhengling said: “The production bases of clean energy are normally located in remote areas, which consume little power. Therefore, the power grid needs to enhance its transmission capacity and distance.”

After thousands of impulse tests, SGCC technicians successfully obtained the parameters of the outer insulation for 1100kV DC UHV transmission lines.

Senior engineer of Smart Grid Research Institute of State Grid Cao Junzheng said: “The system we have developed with independent intellectual property right is of the world’s highest voltage level and the largest transmission capacity.”

A series of technical breakthroughs made China the first country in the world to ever grasp the technology of 1100kV DC transmission. The transmission capacity is 1.8 times that of the operating +/-800kV DC UHV lines.

Deputy chief engineer of China Electric Power Research Institute Liao Weiming said: “Its transmission distance can be as far as 2200km to 2300km.”

Now new energy integration is growing at an average rate of 87% annually. The national grid has become the grid to integrate the largest capacity of clean energy in the world. China has overtaken the U.S. to become the country with the biggest installed capacity of wind power. It’s predicted that the national grid will integrate and transmit 100GW of clean energy in 2015, which is equivalent to integrating 5 Three Gorges projects.

SGCC spokesperson Zhang Zhengling said: “We are not only considering how to ensure power supply. Now we need to think about how to make power utilization more intelligent and environmental-friendly and the national development greener and more sustainable by transforming and upgrading the power grid.”

It’s a worrying situation. If the EU formally announces its decision on an anti-dumping and anti-subsidy case regarding China’s photovoltaic products on June 6, the tax period will be up to 5 years. It will put Chinese solar power enterprises into an unprecedentedly difficult time. However, there is also hope. The PV industry, which is now in a jam, has shown improvement since the beginning of this year.

Faced with the cruel anti-dumping and anti-subsidy, some PV companies don’t waste their time in dealing with the EU but actively seek the domestic market and newly emerging market.

Trina Solar Vice President Yang Xiaozhong said: “We are increasing our efforts in development. The goal is to balance our market distribution around the globe, to make it more well-proportioned. This way, we are able to meet any possible challenges.”

When the U.S. tried to impose high tariffs on Chinese PV products last year, Chinese government began to accelerate the domestic market and came up with a series of supporting policies. After years’ experience, distributed power generation has been considered as the most suitable way for PV generation by industrial insiders, which is mainly applied in commercial areas and individual rooftops. To act in line with the national policy to support the PV industry, SGCC released the Guideline on Integration Service for Distributed Power in February, showing its resolution to support a rapid growth of distributed PV generation, and also offering a solution for on-grid electricity generated by individual rooftops. With a series of new policies, a citizen from Qingdao, Shandong, built a micro solar power generation station of 2kW on his roof. The generated power can be consumed by the family and the extra amount can be integrated on the national grid for sale. It’s China’s first success of integrated household distributed PV power project. 

Xu Pengfei, citizen from Qingdao, said:“It can approximately generate 2800kWh of power throughout the year.”

SGCC spokesperson Zhang Zhengling said:“The user built a micro power generation station himself. And he doesn’t have to worry about grid integration.”

According to insiders, China’s distributed PV generation can exceed 20GW in 2015, which will elevate its commercialized market. It’s predicted that the PV installation in the next 5 and 10 years in China will greatly excel the current goals.

Yang Xiaozhong said: “No matter how EU will vote, it’s unstoppable to develop new energy around the globe. We are confident that China’s PV industry will obtain a sustainable development with a bright future. China will soon become the world’s largest market for PV solar power application.”
