What is an energy storage concept? What is Energy Storage?

Energy storage mainly refers to the storage of electrical energy. Energy storage is also a term in oil reservoirs, which represents the reservoir's ability to store oil and gas. Energy storage itself is not an emerging technology, but from an industrial perspective, it has just emerged and is in its infancy.

So far, China has not reached the level where the United States and Japan treat energy storage as an independent industry and introduce special support policies, especially in the absence of a payment mechanism for energy storage, the commercialization model of the energy storage industry has not yet taken shape.

Energy storage methods: 1. Battery energy storage.

Lead-acid batteries are generally used in high-power occasions, which are mainly used for the storage of surplus energy in emergency power supplies, battery cars and power plants. Dry batteries that can be recharged repeatedly can also be used in low-power occasions: such as nickel-metal hydride batteries, lithium-ion batteries, etc.

2. Inductor energy storage.

The inductor itself is an energy storage element, and its stored electrical energy is proportional to its own inductance and the square of the current flowing through it: e = l*i*i 2. Because inductors have resistance at room temperature, resistance consumes energy, so many energy storage technologies use superconductors.

Inductive energy storage is still immature, but there are examples of applications in the report.

Energy storage, simply put, is to store the electricity generated and use it when it is needed.

From the production of electricity to the final use, the approximate process is:

Production of electricity (power plant, power station) - transmission of electricity (power grid company) - use of electricity (user) and in the above three links, energy storage can be established, so energy storage is divided into power generation side energy storage according to application scenarios; grid-side energy storage; User-side energy storage.

Judging from the current electricity consumption environment dominated by thermal power, hourly use is still the mainstream. That is to say: the power plant sends --- to the power grid--- transmits it to the user for use, and there is no energy storage in the middle.

A small number of power grid companies will use pumped storage to regulate peak and frequency, and pump peak and fill valleys. That is, when there is a surplus of electricity at night, the water from the downstream of the hydropower station is pumped upstream to generate electricity.

With the upgrading of the energy system and the promotion of the dual carbon goal, renewable energy such as solar and wind energy has begun to be widely used. Since wind power and photovoltaic power are greatly affected by the weather and have great instability, energy storage technology plays a vital role. There is a view that the combination of wind, solar and storage is likely to become the future development trend of new energy.

The industry believes that in the next few years, the new energy storage industry will usher in a continuous "acceleration run", the deployment of long-term energy storage systems to meet the needs of large-scale needs will be accelerated, and the coupling development of diversified energy storage technologies will increase in advance.

1. What is energy storage?Energy storage refers to the process of storing energy through a medium or device and releasing it when needed. Generally speaking, when it comes to energy storage, it mainly refers to the storage of electrical energy.

Energy storage technology is a key node for the future energy system to be flexible, inclusive, and balanced.

Second, the core role of energy storageThe role of energy storage can be understood as "power bank".

From the point of view of application.

Energy storage is a key part of the power system, which can be applied in any link of "generation, transmission, distribution and use".

Electricity is ready to use and cannot be stored directly, while distribution and storage can smooth power fluctuations and reduce resource waste.

From the perspective of application scenarios.

It can be divided into various purposes such as user side (self-generation and self-consumption, peak-to-valley price difference arbitrage), power generation side (renewable energy grid connection, reduction of solar and wind curtailment), grid side (power peak regulation, frequency regulation), transmission and distribution side, and auxiliary services (backup power supply for 5G base stations).

Energy storage is the storage of energy, like wind energy, solar energy, and electric energy stored in batteries.

Energy storage is the storage of electricity for reuse.

Energy storage is not only an environmental protection requirement, but also a cost-saving need.

However, the fluctuating power of solar and wind power is a big test for the power grid.

This problem can be solved by the hybrid energy linkage system in the market, such as solar energy, wind energy, energy storage batteries, mains power and diesel generator sets, which can integrate and flexibly use various power generation to ensure the power consumption of the load.

This kind of system can solve the islands, family villas, remote factories, communication base stations, oil drilling microgrids, urban hotels, large industrial parks and other occasions, not only advocating green and environmentally friendly electricity, but also to ensure the stability of electricity use.

Summary. Dear, hello, the difference between user energy storage and independent energy storage, independent energy storage can provide energy storage facilities with various auxiliary services to the power grid, and independent energy storage participates in the frequency regulation and peak regulation capacity market according to its rated capacity. Residential energy storage, also known as home storage, is an important component of distributed energy resources (DER).

Distributed energy supply can achieve cost savings in transmission and distribution, achieve lower costs, improve power quality and energy efficiency. For households, it can reduce the cost of electricity by increasing the proportion of self-consumption and participating in auxiliary services, and at the same time, it can be used as an emergency backup power supply in the middle of the power grid in the face of major disasters and other factors, so as to improve the reliability of household power supply. For the power grid, the rapid increase in the proportion of VRE (fluctuating renewable energy) will further widen the difference between the power generation curve and the power consumption curve, and the configuration of energy storage can transfer power in time to assist the grid to balance power generation capacity and electricity demand. The classification can include grid-connected household optical storage systems and off-grid household optical storage systems.

The grid-connected household photovoltaic storage system can be used to supply power from the grid to the household load or the household photovoltaic storage system to the grid transmission, while the off-grid household energy storage system has no electrical connection with the power grid, which is suitable for remote areas without power grid such as isolated islands. <>

The classification can include grid-connected household optical storage systems and off-grid household optical storage systems. The grid-connected household photovoltaic storage system can be used to supply power from the grid to the household Yuzhushan Ting load or the household photovoltaic storage system to the grid transmission, while the off-grid household energy storage system has no electrical connection with the power grid, which is suitable for remote areas without power grid such as isolated islands.

The core barrier of household energy storage lies in the adaptation and channel advantages with energy storage inverters. The core difference between the so-called large energy storage and household storage lies in the scale, with large energy storage and small household storage. If energy storage is classified according to different storage methods, it can be roughly divided into:

Energy mainly refers to the cyclic process of storing and releasing electrical energy. In layman's terms, it is to store the temporarily excess electricity in some form and take it out and use it when needed, like a large power bank.

Energy storage can smooth the fluctuations of new energy in time and space to a certain extent, match the power load on the power generation side, and ensure the power balance, which has become the only way for the large-scale development of photovoltaic wind power.

Energy storage technology. At present, there are three main technical routes for energy storage, namely mechanical energy storage, electromagnetic energy storage and electrochemical energy storage.

Pumped hydro storage is the most important form of energy storage at present, with mature technology, but high requirements for site selection and long construction period.

Electromagnetic energy storage, including superconducting energy storage and supercapacitor energy storage, has fast response speed and high flexibility, but faces problems such as high energy consumption and safety, and has the narrowest application range.

Electrochemical energy storage is mainly based on lithium batteries, lead-acid batteries and all-vanadium flow batteries, among which lithium battery energy storage has higher energy density, more mature industrial chain support, and more advantageous cost.
