Why should we implement the solar grid connected power supply system?
Solar power generation is a beneficial supplement to traditional power generation. In view of its importance to environmental protection and economic development, all developed countries have made every effort to promote solar power generation. Small and medium-sized solar power generation has formed an industry. There are two ways of solar power generation: photovoltaic power generation and solar thermal power generation. Photovoltaic power generation has the outstanding advantages of simple maintenance, large or small power, and is widely used as a medium and small grid connected power supply.
A solar cell can only produce a voltage of about 0.5V, which is far lower than the voltage required for actual use. In order to meet the needs of practical applications, solar cells need to be connected into modules. The solar cell module contains a certain number of solar cells, which are connected by wires. For example, the number of solar cells on a module is 36, which means that a solar module can generate a voltage of about 17V.
The physical units sealed by the solar cells connected by wires are called solar cell modules, which have certain anti-corrosion, wind proof, hail proof and rain proof capabilities and are widely used in various fields and systems. When the application field needs high voltage and current and a single module cannot meet the requirements, multiple modules can be formed into a solar cell array to obtain the required voltage and current.
Photovoltaic power generation system can be divided into off grid photovoltaic power generation system and grid connected photovoltaic power generation system. The investment of grid connected photovoltaic power generation system is 25% less than that of off grid photovoltaic power generation system. It is an important technical way to improve the scale of photovoltaic power generation to connect the photovoltaic power generation system in the form of micro grid to the grid connected operation of the large grid and support each other with the large grid. The grid connected operation of the photovoltaic power generation system is also the main direction of future technical development, and the range and flexibility of solar energy use can be expanded through grid connection.
PV power generation grid connection means that the direct current generated by solar modules is directly connected to the public grid after being converted into alternating current meeting the requirements of the municipal power grid through grid connected inverter. It can be divided into grid connected power generation systems with and without batteries. The grid connected power generation system with storage battery is schedulable, which can be connected to or removed from the power grid as required, and also has the function of standby power supply. When the power grid is cut off for some reason, it can provide emergency power. The photovoltaic grid connected power generation system with storage battery is often installed in residential buildings. The grid connected power generation system without battery does not have the functions of schedulability and standby power supply, and is generally installed on a larger system.
There are centralized large-scale grid connected photovoltaic power stations for photovoltaic power generation, which are generally national level power stations. The main feature is that the generated energy is directly transmitted to the grid, and the grid is uniformly deployed to supply power to users. However, this kind of power station has not developed greatly due to its large investment, long construction period and large area. The decentralized small grid connected PV, especially the integrated PV power generation of PV buildings, is the mainstream of grid connected PV power generation due to its advantages of small investment, fast construction, small floor area, and strong policy support.
1. Countercurrent grid connected photovoltaic power generation system
There is a countercurrent grid connected photovoltaic power generation system: when the solar photovoltaic system generates sufficient electric energy, the residual electric energy can be fed into the public grid to supply power to the grid (selling electricity); When the power provided by the solar photovoltaic system is insufficient, the load will be powered by electric energy (electricity purchase). Since the direction of power supply to the grid is opposite to that of the grid, it is called a countercurrent photovoltaic power generation system.
2. No countercurrent grid connected photovoltaic power generation system
No countercurrent grid connected photovoltaic power generation system: the solar photovoltaic power generation system will not supply power to the public grid even if it has sufficient power generation, but when the solar photovoltaic system has insufficient power supply, the public grid will supply power to the load.
3. Switched grid connected photovoltaic power generation system
The so-called switching grid connected photovoltaic power generation system actually has the function of automatic two-way switching. First, when the photovoltaic power generation system has insufficient power generation due to cloudy, rainy days and its own fault, the switch can automatically switch to the power supply side of the grid to supply power to the load from the grid; Second, when the power grid is suddenly cut off for some reason, the photovoltaic system can automatically switch to separate the power grid from the photovoltaic system and become an independent photovoltaic power generation system. Some switching photovoltaic power generation systems can also disconnect the power supply for general load and connect the power supply for emergency load when necessary. Generally, switching grid connected power generation systems are equipped with energy storage devices.
4. Energy storage grid connected photovoltaic power generation system
Grid connected photovoltaic power generation system with energy storage device: energy storage device is configured as required in the above types of photovoltaic power generation systems. The photovoltaic system with energy storage device has strong initiative, and can operate independently and supply power to the load normally in case of power failure, power limitation and fault in the power grid. Therefore, the grid connected photovoltaic power generation system with energy storage device can be used as the power supply system for important or emergency loads such as emergency communication power supply, medical equipment, gas station, shelter indication and lighting
