Current situation of the development of the photovoltaic power generation system in China?

With the development of photovoltaic power generation technology, distributed photovoltaic increasingly open to serve the needs of load growth and reduce environmental pollution, improve the energy comprehensive utilization, an effective way to improve power supply reliability.

with the development of photovoltaic power generation technology, distributed photovoltaic increasingly meet the demand of load growth, reducing environmental pollution, improve the energy comprehensive utilization, and the effective ways to improve power supply reliability. Germany began to implement the policy at the beginning of this century, and is a world leader. Relevant European institutions also estimates the development of the technology: in the 1920 s, the world's total solar power will account for 1% of all energy, by the middle of this century, will reach one 5, by the end of this century will be more than half. In this regard, China has carried out some development strategies. Need to improve energy development speed to reduce the cost of energy use, so that more widely use of energy and energy efficiency. Relevant experts believe that by 2025, China's new energy power generation will make up a quarter of the total generating capacity, because solar photovoltaic power generation is more and more frequent. Increase the rate of power generation in order to reduce the cost and the stability of power grid has caused wide attention from all over the world. Today's photovoltaic power generation technology is increasingly mature, and development in the direction of grid-connected power generation and power buildings. The technology in China, of course, there are still some problems. For example, most of the raw materials before get still needs to be imported, and most of the products be shipped abroad. Material price is high, the product price is low. The domestic market has been stagnant, this led to China's photovoltaic industry restructuring. In recent years, with the long-term use of energy, the use of fossil resources such as coal, natural gas and oil is only a short period of time. However, burning fossil fuel emissions of carbon dioxide and oxygen sulfide led directly to the earth's greenhouse effect and acid rain. The large-scale development and utilization of fossil fuels is one of the main causes of human survival environment deterioration. Human beings are facing the dual challenges of economic and social sustainable development. New energy to replace fossil energy is historically inevitable. Therefore, in the limited resources and environmental protection requirements, under the double constraints of human beings should save for a rainy day, looking for alternative sources of energy as soon as possible, this requests us to find alternative sources of energy must be renewable clean energy, and solar energy is one of the renewable energy. Distributed photovoltaic belong to the renewable energy generation, developing very quickly. However, distributed photovoltaic power distribution network brought certain impact to the traditional distribution network protection. Therefore, the study of protection mechanism has very important practical significance.
