7.29 Grid Dispatch

This topic describes the power grid dispatching function.
In a PV power generating system, the short-term fluctuation and periodic changes of the local
illumination may lead to a tremendous power fluctuation, which brings risks to the power grid
running.
The power grid dispatching center should build up a real-time dispatching mechanism to
ensure that the power output from the PV power generating system takes precedence during
the load peak hours. If the power grid is faulty or a voltage or frequency imbalance occurs
between the power generating side and the power consuming side, the power grid dispatching
center sends the active power control and reactive power control command to ensure the
secure power grid running.
As the core device in the communications system of the PV power station, Smart Logger
receives the remote dispatching signals, analyzes the dispatching commands, and sends the
commands to all the inverters connected to it. The power grid dispatching person can set all
the parameters on the WebUI to meet different customers' requirements.
By integrating grid-tied PV system standards of various countries and regions, the Smart
Logger also provides various and flexible power grid dispatching meet different requirements
of countries and regions.
