Energy storage "full of blood resurrection" four areas to open the industry "money" scene

The ever-increasing Energy Storage is becoming another “golden land” in the new energy field. With the increasing number of commercial use cases, energy storage is almost mature on the market. At the same time, in the favorable policies introduced by the two major power grid companies, the energy storage has once again emerged, waiting for the timing of the outbreak.

As the “last mile” of new energy development, energy storage is expected to have an unprecedented “acceleration” in 2019.

Recently, State Grid Corporation issued the "Guiding Opinions on Promoting the Healthy and Orderly Development of Electrochemical Energy Storage". The State Grid will develop electrochemical energy storage on the power supply side, customer side, and power grid side.

Specifically, in terms of the power supply side, it supports the energy storage configuration of new energy generation; it supports the storage of conventional thermal power storage.

On the customer side, investment will be given priority in areas where grid adjustment is difficult and the cost of retrofitting and upgrading is high.

At the same time, it is clear that the energy storage access management, power supply side energy storage and independent pure peak frequency FM energy storage access, refer to the conventional power access management method.

Industry analysis generally pointed out that the paper's intentions and orientations are very clear, and the boundaries and priorities of the development of energy storage at all levels of the State Grid are determined. At the same time, the direction of the energy storage policy mechanism pursued by the State Grid Corporation is publicly defined for the first time.

The Southern Power Grid also continues a similar wind direction. In the draft of the "Guiding Opinions on Promoting the Development of Electrochemical Energy Storage" issued recently, it also involves deepening the research on energy storage impact, promoting the application of energy storage technology, standardizing the management of energy storage and grid, and leading the development of energy storage industry. Big focus tasks.

From the intensive release of the above-mentioned policies, it can be seen that the energy storage will be further developed. To a large extent, this is due to the fact that the energy storage industry is also playing an outstanding role in solving the problem of “abandoning wind and abandoning light”.

As many industry experts predict, multi-energy complementarity with information technology and energy storage technology as the main features will become a new trend of sustainable energy development, and ultimately become one of the important graspers of the future energy landscape. The construction of energy storage power stations in the field of new energy power generation has solved the problem of new energy consumption.

Compared with the independent photovoltaic power generation, after adding the energy storage system, the optical storage joint tracking and scheduling error is significantly reduced, and the energy storage system improves the ability of the photovoltaic power generation tracking and scheduling plan. At the same time, the large-scale energy storage power station built on the side of the new energy power generation has the advantages of large scale, low equipment unit cost, low land construction investment, and low investment in power grid.

In terms of commercial application, the practice of arbitrage on the user side through peak-to-valley electricity price difference, exploration of trial capacity electricity price on the grid side, and promotion of flexible power supply compensation mechanism on the power generation side has gradually increased. However, in the current situation of the energy storage industry policy has not been clear, it is not easy for energy storage projects to achieve meager profit.

At this stage, four major aspects, including peak-to-valley electricity price arbitrage, auxiliary FM service charges, user-side energy storage system participation demand response, and grid-provided auxiliary services, have become important sources of energy storage and the promotion of multi-business models. channel.

"Now the energy storage power station is not obvious in profitability, and financing is difficult, but it can be greatly improved in two or three years." Industry veterans frankly said that in addition to these two profit models in 2019, including distributed energy storage, centralized New profit models such as renewable energy storage and grid-side energy storage will also mature.

In the future, the business model of user-side energy storage is expected to gradually merge with the grid side. As the "investment + operation" business model is more common, that is, the property rights returnee is responsible for the full life cycle operation, when the peak and valley price difference is greater than 0.75, it has profit conditions.

As the economy is stable and the “coal to electricity” project continues to advance, the power gap in each province has expanded dramatically, and energy storage has become another new goal for companies to compete after PV. According to the statistics of the National Development and Reform Commission, the National Energy Administration and other departments, China's energy storage will reach 24 GW in 2025, and there are still dozens of times of development space.

The complexity of the energy storage application scenario determines the development direction of energy storage battery technology. "In the future, large-capacity batteries for power storage and energy storage, and high-power batteries for power storage and energy storage have yet to be technologically innovative."

Horizontal K Type Wind Turbine

This SK type wind turbine is horizontal axis, with PMG generator. The blades is aerodynamic design, so it run fast with high efficiency around 70%~90%. There are some red mark on top of blades usually, this mark is warning mark to brids or something else in air, it's environment-friendly. The blade length could be 1.4m ~ 4.5m, power range is from 2kw to 30kw.
