Photovoltaic + energy storage system is under the supervision of the photovoltaic power generation, with the advancement of energy storage technology and the landing of capital, so the photovoltaic power generation is an economically feasible best combined plan in the development of new dynamics. However, the current stage of photovoltaic + energy-energy application in my country is still in the late stage of development, and there are development bottlenecks. It is necessary for colleagues in the industry to focus on finding more stones that can be touched in the industry.

China’s “Photovoltaic + Energy Accumulator” market

The current energy accumulator market is relatively long-term. Sugar daddy, an industry expert believes that the first choice is on the power generation terminal, photovoltaic + Energy Accumulator (hereinafter referred to as photovoltaic) applications are as of today. Sugar baby All situations are conducive to its development and are also a key purpose promoted by the industry. Because of integrating the national dynamic structure, power generation and Internet companies have requested that wind, pyroelectric or photovoltaic energy storage are a form of common winning, especially optical storage is the clearest business form. The national strategy requests to keep the photovoltaic abandonment rate within 5%. There are many types of control technologies, but photovoltaic + energy storage is a more satisfactory form today, and the market is also moving forward.

For power generation enterprises, photovoltaics generally have a life of 20 years, but due to the abandonment problem, the acceptance of capital and acceptance of capital is unpredictable. The power station has been built and the investment has been improved. The choice of withdrawal key is equally waived, and the increase capacity can be carried out. Although the acceptance of project capital and acceptance of project capital is delayed, the total capital and income is even unsatisfactory, which meets the request of photovoltaic companies, so the photovoltaic companies have the power to do it.

From the Internet company, although it has not participated in the entire process, the adjustment of the output is very good, and the energy acquisition will make the output more stable, which is also profitable for Internet companies. Why is it willing to do it? When the stored electricity is discharged, it is calculated according to the photovoltaic Internet price. It is easy to see that the commercial form of photovoltaic + energy-energy exists because from the authorities, power generation companies, power companies, and power companies to energy-energy, all parties have been guaranteed, achieving a common win.

FromTo be more detailed, the industry’s topics about photovoltaics have been explored, from the end “why photovoltaics increase energy” to “what photovoltaics can do with photovoltaics + energy storage”, and then “how many energy storage is needed for photovoltaics”, to “energy storage should be matched on the DC side or traffic side”, with the depth of the discussion topic, it also represents the continuous progress of photovoltaic technology.

In recent years, the construction of optical projects in my country has also been effective. As of the end of 2018, the cumulative scale of energy storage projects that China has invested and matched with photovoltaics has reached 259.6MW, accounting for 25.7% of the total energy storage projects in China. The expansion rate of the optical storage market is accelerating.

The “Photovoltaic + Energy Accumulation” advantage and challenge

Photovoltaic + Energy Accumulation is a combination of a photovoltaic system plus a battery as an energy storage device to store the energy emitted by the photovoltaic systemSugar baby in the battery. Photovoltaic power generation itself is fluctuating, so that the continuous problem of photovoltaic power generation can be solved. The optical system can quickly and accurately store power, smooth short-term fluctuations, eliminate the most load capacity, and ensure the maximum application rate of solar energy.

Photovoltaic energy utilization has become a trend. There are five types of application scenarios:

One is to improve the self-exploitation rate of photovoltaic self-exploitation and self-use rate, store the unlimited photovoltaic energy in the battery, and release the stored energy when the load is in the middle of the load, which can save electricity costs and income.

The second is to cut peaks and fill valleys. By charging the electricity at the valley value through the energy storage system, discharge electricity at the peak of the electricity price to reduce the electric-degree price. The third is demand management. By increasing energy, the power used during peak production is reduced, and the capacity or maximum demand is reduced, which generally reduces the basic electricity price.

The fourth is the micro-net system. For powerless, short-term areas or offshore islands, photovoltaics and energy-enabled micro-nets can reduce the noise formed by traditional diesel generators. The real technology genius · integrity president x fake can be sluggish.The ultimate male singer is pure, with lower power supply and more economical and reliable.

Fifth, optimize the photovoltaic output curve and save the energy of the local area that the Internet cannot consume first. Sugar baby and connect it to the Internet at other times to reduce the waste caused by abandoned light electricity limit.

Based on the application scenario, the advantages of optical system are clear at a glance, but the development of optical system still faces many problems and challenges. Relevant people believe that before the energy storage is achieved, photovoltaic power generation can only be the secondary angle of the power system.

In terms of resources, my country has rich steel mine resources, and steel mines are the main original information for producing steel batteries. This provides “no.” This provides resource guarantees for energy conservation, but the problem is that the development and application level of domestic steel resources is still very low, and a large number of steel information is still imported from abroad.

In terms of policy, the major policy departments related to energy industry are planned in a grand manner, and have not truly implemented the implementation details, and have not formed an internal market environment conducive to energy industry development. Compared with the value of energy development, there is still a lack of incentive policies for energy production.

In terms of business form, energy-energy profit-making forms should be explored in the fields of power assistance services and power distribution, and to enrich the profit-making forms of energy.

Multiple policies promote the development of light industry

In the early stages of industrial development, the impact of policy cannot be underestimated. Domestic optical applications have been released, and the new policy of “May 31” has been released, and optical applications have attracted attention from the industry. Later, Xinjiang, Xidiao, Hefei and other regions that have laid out optical applications have also repeatedly issued policies to help industrial development without any effort. It is worth mentioning that the promotion of Xinjiang’s policies to provide optical applications this year is particularly obvious.

1. With the new “May 31” policy in 2018, the photovoltaic industry supplement standards and photovoltaic indicators have tightened, and a “urgent car” has caused the photovoltaic market to fall into a sluggish state. On November 2, 2018, the National Bureau of Dynamics held a photovoltaic meeting and stated that the supplement will continue until 2022, and the original “13th Five-Year Plan” scale has been adjusted, and the photovoltaic market began to recover. At the same time, photovoltaic companies will focus on energy generation, and photovoltaic combinations have once again become the industry’s focus.

2. In September 2018, the Hefei Municipal Bureau issued the first distributed optical energy storage policy: “Opinions on Promoting the Continuing Healthy Development of Photovoltaic Production” (hereinafter referred to as “Opinions”), using the photovoltaic energy storage system as the support focus and for the energy storage systemGive charge and supplement the charge. “Opinions” point out that for photovoltaic energy storage systems that have been released and operated online, the project components, energy storage batteries and inverters shall be notified by the Ministry of Industry and Information Technology to inform the company of the company’s products or products recommended by “Hefei City Recommended Photovoltaic Products Directed Table” from the next month, the energy storage system will be charged 1 yuan/kW at a time of supplementary charge of 1 million yuan per kilowatt, with a maximum annual supplement of 1 million yuan for a project.

3. On February 19, 2019, the Xinjiang Autonomous Region Development and Reform Commission issued the “Notice on the TC:
