For the purposes of this document, the following terms and definitions and those defined in GB/T 19964 and GB/T 31464 apply.
3.1
photovoltaic (PV) power station
The electric power generation system and auxiliaries which directly transform solar radiant energy into electric power through the photovoltaic effects of the photovoltaic cells.
3.2
PV power forecasting
The forecast which is made on the active power of the photovoltaic power station through the technology and means including meteorological conditions and statistical regularity.
3.3
grid integration test for PV power station
The test to determine the grid integration performance in five aspects including the power quality, active power/reactive power control ability, low-voltage ride through ability, voltage/frequency adaptation ability and active power output characteristics of the photovoltaic power station.
3.4
dispatching automation system; it shall transmit to the grid dispatcher in time, accurately and reliably, the equipment operation information, meteorological information and power forecasting information of the primary systems and secondary systems of the photovoltaic power station.
5.1.7 The photovoltaic power station shall report to the grid dispatcher in time the alterations of the primary system equipment and secondary system equipment of the photovoltaic power station and their safety protection schemes.
5.1.8 When the photovoltaic power station quits operation in emergency or trouble, it shall report to the grid dispatcher immediately and start the grid-connected operation once again in accordance with the dispatching instructions only after obtaining the consent of the grid dispatcher. The photovoltaic power station shall keep records of accidents and report to the grid dispatcher in time.
