What is The Meaning of on-grid System?
On-grid system refers to a power generation system connected to the power grid.
The following is a detailed explanation of the on-grid system:
On-grid system refers to the connection of power generated by power generation equipment (such as solar photovoltaic panels, wind turbines, etc.) to the public power grid to achieve power sharing and allocation. The system usually includes power generation equipment, inverters, grid connection equipment and other components. The inverter is the core of the on-grid system. It is responsible for converting the direct current generated by the power generation equipment into alternating current and adjusting the voltage and frequency to meet the requirements of the power grid.
When the power generated by the power generation equipment exceeds the load demand, the excess power will be uploaded to the power grid through the grid connection equipment for use by other users; when the power generated by the power generation equipment is insufficient, the power grid will supplement the power to meet the load demand.
On-grid system is widely used in renewable energy power generation such as solar photovoltaic power generation and wind power generation. In solar photovoltaic power generation, the grid-connected system can connect the electricity generated by photovoltaic panels to the grid, achieving self-sufficiency in electricity for households, enterprises and other users, and sell excess electricity to the grid. In wind power generation, the grid-connected system can also connect the electricity generated by wind turbines to the grid, providing clean and renewable energy for more users.
The grid-connected system has the following advantages:
(1) Power sharing: The grid-connected system can connect the power generated by power generation equipment to the grid, achieve power sharing and allocation, and improve power utilization efficiency.
(2) Clean and environmentally friendly: The grid-connected system usually uses renewable energy as power generation raw materials, such as solar energy and wind energy, and has the characteristics of clean and environmental protection.
(3) Economic benefits: The grid-connected system can sell excess electricity to the grid, bringing economic benefits to users.
In summary, the grid-connected system is an efficient, environmentally friendly and economical power supply method with broad application prospects and development potential.
