In the rapid economic development, the energy shortage has attracted much attention. Therefore, in order to alleviate and solve this issue, it is necessary to carry out the discovery of new energy, especially the development of renewable energy. The application of solar photovoltaic is extremely valuable in dealing with this problem. Solar photovoltaic system is prone to energy loss in the energy conversion. At the same time, much attention should be paid to the choice of energy storage system to reduce energy loss.
As we know, the power generated by the solar energy has a certain degree of discontinuity, and it is difficult to break through the time limit to achieve all-weather power generation. In order to better meet the needs of social life, we can use energy storage systems and equipment to achieve continuous supply. The more common energy storage systems are divided into three categories, namely super capacitor energy storage, flywheels storage and electrochemical batteries.
It is necessary to conduct a systematic analysis to better understand the value of these systems. This article comprehensively elaborates the main features of the solar photovoltaic energy storage system and introduces the main principles of its work.
The battery is the main representative in the field of electrochemistry, which can realize the conversion of solar energy to DC power. The main way to obtain this energy is redox. The tributary power obtained by conversion will be supplied to the load for use. At present, electrochemical media mainly include several types, such as lead acid, lithium ion, metal hydride nickel, etc. Among them, lead-acid batteries are more effective and more widely used.
Flywheel energy storage system is a relatively new technology with more outstanding advantages. It has strong economic benefits and significant safety and reliability, meeting the needs of green and high efficiency. Its energy supply is mainly through wind energy, excess electric energy and solar energy, which greatly highlights the system characteristics. In this technology, the two-way flywheel has a high conversion rate, especially when it is in a high peak state. At the same time, this kind of system power management is relatively simple and easy to operate. As the system can be designed more flexibly under the given voltage and current, it has a good prospect and huge market potential.
At present, many countries are actively carrying out research on super capacitor energy storage. As a primary power supply, it has a wider range of applications. First of all, the super capacitor can meet the high power requirements of electric cars when accelerating and starting.
Secondly, super capacitors can be applied to satellites. Hybrid power is a common power source used in satellites, that is, a combination of batteries and solar energy. After the installation, the improvement of satellite communication capabilities is realized.
Super capacitors can realize the effective supply of opening energy. It can fully operate in a small current environment, which means that solar photovoltaic cells can realize the charging function of super capacitors, greatly improving the effectiveness of solar photovoltaic generation.
We can find that the energy storage system has many advantages in itself, meeting the high-density energy demand, effectively reducing costs and achieving higher energy conversion. In view of the limitations of a single energy storage system, we must combine different energy storage systems to maximize the role of them in solar photovoltaic applications.
