The Advantages Of Grid Connected Power Generation Systems

After installation, the grid connected power generation system can convert the direct current output by the solar cell array into alternating current with the same amplitude, frequency, and phase as the grid voltage, and effectively connect with the grid and transmit electricity to the grid. Next, we will introduce the advantages of grid connected power generation systems.

The flexibility of grid connected power generation systems lies in the fact that when the sunlight is strong, the photovoltaic power generation system supplies power to AC loads and delivers excess energy to the grid; When insufficient sunlight is found during operation, that is, the solar array cannot provide enough electricity to the load, electricity can be obtained from the grid to supply power to the load. And it has many advantages. For example, on cloudy or rainy days or at night, the power grid supplies power to the load, so that the system does not need to be equipped with energy storage devices, which can not only reduce the cost of the system but also bypass it. The hassle of maintaining and replacing batteries increases the reliability of power supply; Or can the electricity generated when there is sunlight be supplied to the load inside the building, and the excess can be fed back to the power grid; The grid connected power generation system is completely unrestricted by the state of charge of the battery, and can store and extract electricity from the grid at any time; After installation, it can be seen that when designing the tilt angle of the solar cell array, the angle corresponding to the large amount of solar radiation received within a year can be taken. In actual use of the power generation of series solar cells, large cells can be achieved.

In addition, the intensity of solar radiation is high in summer, and the electricity generated by solar cell arrays is relatively large. Summer is also a peak period for electricity consumption, which has a certain effect on peak shaving of the power grid. Completely unrestricted by the battery's state of charge, it can store or receive electrical energy from the grid at any time during use; When designing the tilt angle of solar cells, it is necessary to match the large amount of solar radiation that can be collected throughout the year. In this way, the grid connected power generation system can utilize the power generation capacity of the solar cell array.

In summary, the electricity generated by the grid connected power generation system is provided to the power grid, which serves as an energy storage device, saving batteries. Compared with off grid solar photovoltaics, it can reduce construction investment by 35% to 45% in energy generation systems, greatly reducing power generation costs. Backup batteries can improve the average interval between system failures and secondary battery contamination. Alternatively, solar cell modules can be perfectly integrated with buildings in the design, which can generate electricity, serve as building and decorative materials, fully utilize material resources, and play multiple functions. This not only helps to reduce building costs, but also increases the technological content of the building through grid connected power generation systems.
