Explore battery energy storage technology as a new trend in the development of power systems

Explore the new development trend of battery energy storage technology in the power system. By 2020, the proportion of non-fossil energy will reach 15%. Renewable energy such as wind energy and solar energy will be widely used, and the development of renewable energy is unstoppable. The biggest feature of renewable energy is intermittent, intermittent and instability, which brings a lot of trouble to the power grid. The grid balances power supply and load. As far as the grid is concerned, both sides are random and uncontrollable. Therefore, it is necessary to develop a skill to solve this problem. And this technique is another hot topic battery storage that has been brought out by the infinite prosperity in recent years. Electricity, as a commodity, always has a problem, and that is storage. The power system is faced with instant release. The key to stable and safe operation of the system lies in whether the power supply is reliable, adjustable, and random, and whether some techniques can be used to balance the load. However, when renewable energy is connected to the grid, this approach will fundamentally change, not because of demand, but because of resources. UdoNiehage, CEO of Dynamic Affairs of Siemens Power Transmission and Distribution Group, said that the future trend of the grid is to shift from the traditional way of'load determines power generation' to'power consumption depends on power generation'. With the increase in the use of renewable energy, this trend will become more apparent. The essence of energy storage is to complete the storage of electrical energy and release it when needed. The emergence of this technology has completely changed the processing, transmission and use of power systems. Throughout the use of renewable energy, energy storage is essential. Regarding the power distribution and other links of the power system, the support of energy storage technology is required. When renewable energy is connected to the grid, energy storage is not the only way to solve all problems. In fact, this is a huge system that needs to be summarized. Internationally, the visible method is to use demand-side management, such as a series of induction use of electric vehicles, cogeneration, and energy-saving facilities, to solve the problem of renewable energy in the post-era. These methods are still in the development stage, and their use is unclear. In fact, energy storage is now considered to be a more useful means. It can be considered a use for receiving renewable energy. From the perspective of scientific research, energy storage technology has seen a glimmer of hope in recent years. According to my country's wind and solar power generation plan, the installed capacity of wind power will reach 15 gigawatts in 2015. At the same time, according to the Wind Power and Photovoltaic Power Supervision Report of the my country Electric Power Regulatory Commission, as of the first half of 2010, the lack of wind power in my country has led to a total of 2.776 billion kWh of wind curtailment. Wind curtailment is also relatively serious. How to truly realize the effective use of renewable energy power generation has become the focus of the market. Large-scale, high-efficiency energy storage technology is the most useful core skill to complete the use of renewable energy such as wind and solar energy, and is a key skill to improve the peak shaving capacity of the grid and the compatibility of renewable energy grid-connected, and build a strong intelligence Power grid. The development of energy storage technology is actually to explore new ways to develop the power system. The my country Electric Power Research Institute of the Institute of Superconductivity said in the 2011 Energy Storage System Industry Forum that according to the trend of the maximum load capacity, the current resources can no longer support us, and the practical significance of reducing the peak value of the power grid has changed. , After storage, the technology gets the transition from power transmission to power transmission direction. Energy storage skills are complex and multidisciplinary, and are constantly updated frontier strategic skills. We don’t think energy storage is a complicated skill. There is still a long way to go before large-scale commercialization, but it certainly has great potential.
