PV affordable Internet access is facing a test, and the integrated development of "PV +" m

At present, photovoltaic and other renewable energy not only face the competition of traditional energy industry, but also compete for market space within renewable energy. Therefore, it is very important to improve the market competitiveness of photovoltaic industry and realize the high-quality development of photovoltaic industry. Under the background of multiple constraints of centralized photovoltaic power stations and photovoltaic parity on the Internet, vigorously develop the "photovoltaic +" mode represented by fishery light complementarity and agricultural light complementarity, in order to optimize and improve the comprehensive benefits and increase the non power generation income of photovoltaic power stations, which has become an inevitable choice for the photovoltaic industry

With the introduction of a series of new national photovoltaic policies, the era of photovoltaic affordable Internet access is accelerating. At the 4th China "photovoltaic +" innovation and development forum held recently, people in the industry agreed that in the face of the upcoming post subsidy era, the photovoltaic industry needs to get rid of the dependence on traditional subsidies, accelerate technology and mode innovation, strive to improve the high standard, high quality and high efficiency of the photovoltaic industry, and realize the healthy, rational and sustainable development of the photovoltaic industry. Among them, exploring diversified development modes with "photovoltaic +" has become an effective way for the industry to move towards high-quality development.

Affordable Internet access brings test

In the future, under the background of the national promotion of the reduction of renewable energy costs and affordable Internet access, renewable energy such as photovoltaic will not only face the competition of traditional energy industries, but also compete for market space within renewable energy. Therefore, in order to get rid of the dependence on subsidies and increase the non power generation income of photovoltaic power stations, "photovoltaic +" mode came into being. This model can not only reduce the comprehensive cost and improve the efficiency, but also play an important role in promoting the high-quality development of the whole photovoltaic industry.

"The 'photovoltaic +' model is an important form to promote the diversification and high-quality development of the photovoltaic industry." Tang Xuewen, director of the new energy department of Jiangsu Energy Bureau, said that the scarcity of land for photovoltaic projects is one of the bottlenecks restricting development. Under the background of multiple constraints of centralized photovoltaic power stations and photovoltaic parity on the Internet, vigorously develop the "photovoltaic +" mode represented by fishery light complementarity and agricultural light complementarity, in order to optimize and improve the comprehensive benefits, which has become the inevitable choice of photovoltaic power generation.

The reporter of economic daily learned that compared with the single construction of photovoltaic power station, "photovoltaic +" mode has many advantages. On the one hand, combining photovoltaic power generation with modern agriculture and fishery can not only ensure the power demand of fishery and agriculture, reduce breeding costs, but also obtain certain profits from fishery and agriculture, reduce comprehensive costs and improve benefits. It has comprehensive cost advantages and is an important way to access the Internet at flat prices.

On the other hand, "photovoltaic +" can break through the land bottleneck of photovoltaic power generation. This integrated development can realize the comprehensive utilization of multiple energy sources and improve the unit land use efficiency; At the same time, as a new type of agriculture, combining photovoltaic with eco-tourism, beautiful villages and characteristic towns has not only increased agricultural income and farmers' income, but also promoted the revitalization of beautiful China and villages.

"However, this model also faces great challenges. Due to low profits, it may also face losses. Therefore, the realization of profits depends more on photovoltaic power generation subsidies." Tang Xuewen said that under the background of no subsidy and parity Internet access in the future, how to truly reflect the comprehensive benefits of the "photovoltaic +" mode needs to be further explored.

Integration and acceleration of "photovoltaic +" mode

In fact, due to the acceleration of affordable Internet access, an unprecedented upsurge of innovation has been set off among the relevant enterprises in the upstream, middle and downstream links of the whole photovoltaic industry chain. Various new processes and technologies emerge one after another, and the industry records are constantly refreshed. All kinds of "photovoltaic + energy storage", "photovoltaic + multi industry", "multi energy complementarity" and "comprehensive energy management" In order to express the rapid integration and development of the "photovoltaic +" mode, the pace of industry transformation and upgrading is accelerating.

The reporter learned that, as the path of cross-border integration of photovoltaic, the main modes of "photovoltaic +" currently include "comprehensive utilization of multiple energy", "combined development with various industries" and "combined with the reform of social development mode". Cai Gang, director of Zhejiang Provincial Energy Bureau, said that under the background of the country's vigorous development of low-carbon green economy, new energy transformation requirements have been put forward for many industries, providing more possibilities for "photovoltaic +". At the same time, technological progress has also brought breakthrough changes to the development of "photovoltaic +".

Photovoltaic is developed in combination with various industries and has a variety of application scenarios. According to Yi Yuechun, vice president of the General Institute of hydropower and water resources planning and design, combining agriculture, desertification control, fisheries, tourism and photovoltaic applications can generate electricity at the top and control desertification at the bottom, and can also combine planting, fish farming and ecotourism. At the same time, it can increase the income of the poor, use more land, improve land use efficiency and output value, and increase the proportion of low-carbon energy, It is also of great significance to improve the proportion of local non fossil energy and pollution control.

Taking the Kubuqi Desert project participated by Chint new energy as an example, the project rents the unused wasteland of farmers and herdsmen for construction, and the greening and sand fixation project has completed a total of 1500 mu, with remarkable sand control and greening effect. At the same time, from construction to operation, the project has participated in the construction of more than 3000 labor workers, helped more than 800 poor people, and brought nearly 100 million yuan of operating income to relevant building material enterprises. The subsequent planting and breeding of the power station project will continue to drive the surrounding areas to become rich.

The combination of photovoltaic and social development model reform is mainly reflected in the reform of photovoltaic and power system and the integration with the Internet. Yi Yuechun said that "photovoltaic + power system reform" is expected to form a strong driving force to promote reform on the market demand side; The combination of photovoltaic, Internet and big data can promote the cross-border integration of energy industry and information industry, realize the intelligent matching and collaborative operation of energy production and use, and improve the production efficiency of the whole society.

"In the future, with the trend of continuous technological innovation and declining cost of photovoltaic system, business models and schemes suitable for different application scenarios will become more and more diversified, and photovoltaic applications will also be transformed into a new stage of development aimed at reducing cost, improving efficiency and achieving parity." Liu Yiyang, Deputy Secretary General of China Photovoltaic Industry Association, said.

"Photovoltaic + energy storage" has great potential

The continuous exploration of "photovoltaic +" is an epitome of photovoltaic enterprises' continuous pursuit of mode innovation and technological innovation. Liu Yiyang pointed out that the current development environment has both very severe challenges and development opportunities for Chinese photovoltaic enterprises. The key to seize the opportunities lies in technology and application innovation. The key to success in the challenge lies in the model innovation of affordable or low-cost business.

Liu Yiyang believes that with the change of market demand, the significant improvement of the technical level of various enterprises and the intensification of competition, the characteristics of differentiated development in photovoltaic application innovation are becoming prominent. The "photovoltaic + energy storage" application project focuses on technical demonstration and mode verification. With the gradual deepening of the understanding and understanding of energy storage by new energy enterprises, "photovoltaic + energy storage" The mode of diversified application and multiple benefits will develop rapidly.

Referring to the importance of "photovoltaic + energy storage", Wu Xinping, deputy chief engineer of electromechanical branch of Guangdong water resources and power planning, survey, design and Research Institute, said that as a new energy, photovoltaic puts forward higher requirements for the stability, continuity and reliability of power supply to the power grid, and the power grid needs to set aside a certain standby capacity for absorption.

In this regard, Wu Xinping introduced the mode of seawater pumped storage. He said that the combination of seawater pumped storage and photovoltaic system can improve the frequency regulation accuracy of power grid through automatic frequency control, have faster response speed and wider regulation range, and solve the problem of frequency instability caused by large-scale new energy grid connection.

The industry is also optimistic about the application prospect of "photovoltaic + energy storage". Yi Yuechun believes that "photovoltaic + energy storage" can alleviate the short-term fluctuation of photovoltaic power generation, cut peak and fill valley, and make solar power generation play a greater role in the future power system. In addition, he also said that the integration of photovoltaic and smart microgrid can take advantage of the universality of photovoltaic power generation and the characteristics of better matching with the load curve to promote the cost reduction and efficient utilization of smart microgrid.
