Energy storage is an important support of modern power system

The modern energy system is a concept of development, is relative to the old fossil fuel-dominated energy system, with its high efficiency, low carbon, clean and other characteristics, energy consumption tends to "0 carbon" target, which means that the modern energy system of new energy, renewable energy, etc. occupy a large proportion of As a buffer to improve power quality, energy storage can be used as a shifting for the transmission end. In the field of distributed concept, storage energy as the storehouse of power flow plays a key role in the interconnection of energy and the Intelligent Transportation Network, which integrates new energy vehicles. To understand the role and status of energy storage, we need to first understand the building process of modern power system.
The establishment of modern energy system is based on the repeated supply-side adjustment and the innovation of consumption pattern.
In the process of transforming the old energy system into the new energy system, the energy supply side and demand side need a relatively balanced transition, excessive or improper administrative intervention will lead to imbalance and ultimately reflect the market. For example, in the process of excess capacity, the 2016 coal market imbalance in supply and demand, directly led to soaring coal prices. The establishment of modern energy system is actually the process of energy remodeling, whether it is the reform of energy supply side or the guidance of demand side, it is in the level of quantitative change to adjust supply structure occupies the dominant position, the consumption pattern is subordinate status status. This quantitative change has not changed the existing technology application, or from the old energy system to the quasi modern energy system process, there is no absolute technological breakthrough, that is, in the quantitative phase, technology-driven energy economic growth is no longer the main, in other words, The change of energy consumption pattern will play a major role in energy economy growth at this stage. In addition to the advantages of energy consumption mode innovation, modern energy system should include the qualitative effect of technological innovation or breakthrough as the first productive force.
In the modern energy system, storage can not be eliminated, but an important reality support. Energy interconnection is the trend, all forms of energy fusion is actually the relationship of unity of opposites. From the point of view of global energy interconnection, theoretically can eliminate the existence of energy supply side storage form, but in reality, due to the emergence of reverse globalization, energy security awareness and strategic adjustment, the global energy interconnection between the "0 marginal" can only be a strategic direction or trend. Therefore, in the modern energy system, the value of energy storage is not only the strategic significance, but also the important reality support.
For the energy supply side, the existence of the storage form is not to create the value with the breakthrough technology Miracle, its existence is very important for the initial new energy generation to be used effectively in the isolated island state, and the existence of the energy storage form is the structural innovation in the process of the power supply side structure adjustment. For the energy demand side, the progress of the cleaning process can not be separated from the existence of the storage form. With the adjustment and optimization of the new Energy vehicle policy, the popularization of the storage form in the consumer end may show a rapid growth trend. Of course, storage in the modern energy system is also faced with a great challenge, the level of technology application to bring consumer market standards lack of uniformity, will lead to consumer enthusiasm is not high.
