  Grid 10 kV and above distributed photovoltaic field station-side "four can" technical programme     Distributed photovoltaic "four can" refers to observable, measurable, adjustable, controllable. The specific meanings are as follows.   Observable: Realise distributed PV station data collection, including active, reactive, voltage, current, switching information and other data, so that users and dispatchers at all levels can understand the operation of distributed PV stations in real time.   Measurable: Realise accurate power prediction of distributed PV power generation, including medium-term (0h-240h), short-term (0h-72h), and ultra-short-term (15min-4h) power prediction data, to ensure accurate and controllable operation of the station.   Adjustable: The main station of dispatching automation realises the automatic adjustment of active power and reactive power of the stations through control devices, such as group control and group regulation system: AG...
