　　Suggestions on AAA Ni-MH batteries energy storage technology to support the development of distributed energy resources

　　Electrochemical energy storage batteries are becoming an emerging member of the energy storage family due to their advantages of modular assembly and high energy conversion efficiency. Representative energy storage batteries include lithium-ion batteries, sodium-sulfur batteries, and all-vanadium flow batteries. wait. However, in the process of AAA Ni-MH batteries energy storage technology demonstration and commercial operation, there are also problems such as high construction cost of energy storage AAA Ni-MH batteries systems and low number of cycles under deep charge and discharge conditions. On how to promote the sustainable development of the AAA Ni-MH batteries energy storage industry under the existing AAA Ni-MH batteries energy storage technology conditions, the following suggestions are put forward:

　　(1) Energy storage and renewable energy should be planned and developed simultaneously. Since renewable energy power generation is unstable and intermittent, shallow charging and discharging of energy storage batteries can achieve smooth output of renewable energy, reduce the impact of renewable energy access on the power grid, and greatly increase the number of connections to the power grid. Renewable energy generates electricity, and shallow charging and discharging can greatly extend the cycle life of energy storage batteries. Therefore, while planning new energy power generation and grid transmission lines, corresponding energy storage solutions should be provided to promote the simultaneous development of energy storage and renewable energy.

　　(2) Widen the peak-valley electricity price difference and time-of-use electricity price difference, and implement energy storage electricity price policy. Widen the peak-valley electricity price difference and time-of-use electricity price difference to achieve reasonable allocation of power resources and create energy storage investment value. Promote energy storage electricity price policies, and form renewable energy on-grid electricity prices that include energy storage supporting equipment through cost-benefit accounting.

　　(3) Explore new business models for the energy storage industry. The energy storage industry is an emerging industry. Promoting emerging industries is inseparable from the innovation of business models. It is recommended that relevant government management departments and scientific and technological units explore business models or market mechanisms such as clean development mechanisms, financial leasing, and energy contract management in accordance with economic laws to promote Sustainable development of the energy storage industry.

　　(4) Promote the market-oriented operation of distributed optical storage power stations. Inspired by the country's policy of strongly supporting distributed photovoltaic power generation, we should actively promote the research and demonstration operation of rooftop photovoltaic power stations equipped with energy storage systems, tap the potential market demand for community energy storage systems, and sell excess power directly to large power consumers. Instead of selling to power companies, explore the market-oriented operation mechanism of distributed photovoltaic power storage stations for self-use and other uses to achieve the sustainable development of the energy storage industry.
