Photovoltaic power stations connected to the public power grid generally need to be connected by special lines, T access or through the user's internal power grid. Here's how it works:
Dedicated line access is to directly connect the photovoltaic power station with the public power grid and supply power through a dedicated line. This method is usually suitable for situations where the capacity of the photovoltaic power plant is small and there are dedicated lines in the area.
T access is to connect the photovoltaic power station to the public grid through the T-shaped connector, the power generated by the photovoltaic power station is injected into the public grid through the connector, and the electrical equipment obtains power from the public power grid. This method is suitable for the situation that the photovoltaic power station has a large capacity and there are T-type connectors in the area.
The electric energy generated by the photovoltaic power station is injected into the user's internal power grid through the power grid line, and the electrical equipment obtains power from the user's internal power grid. This method is suitable for the situation that the capacity of the photovoltaic power station is small and the user's internal power grid can meet the electricity demand.
In general, PV power stations connected to the public power grid need to choose the appropriate connection method according to the actual situation to ensure the safe and stable operation of the PV power station and meet the relevant policy requirements.
