Promote clean energy utilization and photovoltaic power generation has great potential

Electricity is an energy source powered by electrical energy. Whether it is industrial production or daily life, they are inseparable from the support of electricity. Generally speaking, people are relatively familiar with hydropower, thermal power, geothermal power, etc., but are relatively unfamiliar with photovoltaic power generation. So, what is photovoltaic power generation?

Photovoltaic power generation uses the photovoltaic effect of semiconductors to directly convert light energy into electrical energy. The basic component, the solar panel, is a way of converting light into electricity. Solar cells are packaged and protected after being connected in series to form a large-area solar cell module. Together with power controllers and other components, a photovoltaic power generation device is formed. A photovoltaic power generation device that looks simple on the outside actually plays a huge role. In order to promote the development of photovoltaic power generation industry, relevant departments in my country have issued a number of policies.

In May 2019, the National Energy Administration officially issued the "Notice on Matters Concerning the Construction of Wind Power and Photovoltaic Power Generation Projects in 2019". The notice clearly stated that classified management will be implemented for the construction of photovoltaic power generation projects in 2019, competitive allocation will be adopted for projects that require state subsidies, and the construction of affordable grid-connected projects will be actively promoted, with priority given to projects with low subsidy intensity and large reductions.

Under the guidance of relevant policies, the construction of photovoltaic power generation projects is carried out in an orderly manner. According to statistics, as of the end of June 2019, the cumulative installed capacity of photovoltaic power generation nationwide was 185.59 million kilowatts, a year-on-year increase of 20%, with an additional 11.4 million kilowatts. Among them, the installed capacity of centralized photovoltaic power generation was 130.58 million kilowatts, a year-on-year increase of 16%, with an increase of 6.82 million kilowatts; the installed capacity of distributed photovoltaic power generation was 55.02 million kilowatts, a year-on-year increase of 31%, with an increase of 4.58 million kilowatts.

At present, when the concept of energy conservation and environmental protection is vigorously advocated, solar photovoltaic power generation has been widely praised for its advantages such as no risk of depletion, safety and reliability, no noise, and no pollution emissions. Different from traditional centralized power generation, solar photovoltaic power generation is a new type of power generation and comprehensive energy utilization with broad development prospects. It advocates the principles of nearby grid connection, nearby power generation, nearby conversion and nearby use.

From another perspective, solar photovoltaic power generation can not only effectively provide power generation for systems of the same scale, but also effectively solve the problem of power loss during voltage boosting or long-distance transportation, and has a long service life. . With the advancement and maturity of technology, "photovoltaic + energy storage"quo;A multiple complementary energy power generation microgrid system will be formed to achieve photovoltaic residual power storage, combined with energy storage, to achieve a higher production capacity level.

As far as secondary reheat power generation technology is concerned, our country has made corresponding progress and has significant advantages in thermal power design, equipment manufacturing, operation and maintenance management, etc., especially when people are concerned about The environmental protection emissions have also reached the best level in the world, achieving ultra-low emissions from flue gas desulfurization, denitrification, and dust removal, zero discharge of desulfurization wastewater, and a high utilization rate of solid waste.

In fact, cutting-edge technologies such as the Internet of Things and cloud computing also provide strong support for the power industry to realize intelligent transformation and upgrading. For example, 5G communication technology. 5G communication technology provides a better wireless communication solution for the development of the ubiquitous power Internet of Things, and brings a beautiful and bright prospect to the ubiquitous power Internet of Things.

With the advent of the 5G, Internet of Things, and big data era, expanding the capabilities of data centers to the edge has become an inevitable trend in the next stage of technological development, which has a profound impact on the communication of power systems. The Internet has put forward higher requirements. In the future, cooperation between mobile communication network service providers and power supply companies will become more frequent, and they will jointly explore the possibility of deep integration of 5G, Internet of Things and other technologies with the power system to seize new development opportunities in the power industry.

Clean and low-carbon has become an irreversible trend. The energy revolution characterized by the deep integration of new energy and information technology is pushing human society into a new energy system. With the increasing support from national policies and funds, as well as the continuous advancement of science and technology, the benefits of photovoltaic power generation will be improved, and the user experience will be further optimized.
