The development prospect of distributed photovoltaic from national planning

Issuing time:2018-10-16 00:00

Distributed photovoltaic power generation refers to the photovoltaic power generation facilities built and operated on or near the site of users, which are mainly used by users on their own side, and are characterized by redundant power grid and balanced regulation in the distribution network system. The state has been actively encouraging the distributed photovoltaic power generation system and has introduced a series of supporting measures. In particular, the 13th five-year plan for power development, released late last year, sets an extraordinary development goal for distributed photovoltaic: "by 2020, the installed capacity of solar power will be more than 110 million kw and distributed photovoltaic will be over 60 million kw". All indications show that distributed pv, especially family distributed pv, is about to enter a period of rapid development opportunities.

I. speed up the development of distributed photovoltaic, but the gap with developed countries is still large

For many years, the state has issued a series of policies for the construction of domestic photovoltaic power stations in order to mitigate the impact of the European and American photovoltaic double-reverse policies on enterprises in China. Although this policy effectively solved the problem of overcapacity of photovoltaic modules, it led to the extraordinary development of solar power stations in China, while the development of distributed photovoltaic was slow and the proportion was seriously out of proportion.

At the same time, compared with developed countries, the proportion of distributed pv in China is seriously low. The proportion of distributed pv in foreign countries is about 80% in Germany, while that in the United States and Japan is about 50%. By the end of 2016, China had a cumulative installed capacity of 77.42 million kw of photovoltaic power generation, of which 10.32 million kw was distributed, accounting for 13.3%. In developed countries in Japan, Europe and the United States, the proportion of large power stations and household distributed photovoltaic is maintained at 1:1, while in China, the proportion of large photovoltaic power stations is as high as 80%. As most large power stations are built in remote areas of northwest China, they cannot effectively solve residential electricity consumption. Moreover, the lagging construction of power grid has led to frequent light abandonment and serious resource waste.

2. In the future, the rapid development of distributed photovoltaic is expected, and policy is the biggest driving force

At present, relevant national energy planning has proposed extraordinary development goals for distributed photovoltaic. According to the 13th five-year plan for power development, the installed capacity of solar power will be more than 110 million kilowatts by 2020, and distributed photovoltaic capacity will be over 60 million kilowatts. In terms of the installed capacity of distributed photovoltaic, 4.24GW was added in 2016, with a year-on-year growth of 200%, with a cumulative installed capacity of 10.32GW. There is still 50GW space from the planned target in 2020. In order to guarantee the realization of the target, the country has introduced a series of policies to support, the most typical is price policy support.
