A medium-and-long term generating capacity prediction method for a regional photovoltaic power station group

Abstract

The invention discloses a medium-and-long term generating capacity prediction method for a regional photovoltaic power station group. The method comprises the step of acquiring monitoring data of the regional photovoltaic power station group and each photovoltaic power station in the regional photovoltaic power station group in a same continuous time period; selecting a model photovoltaic power station from the photovoltaic power stations according to the monitoring data; predicting the medium-and-long-term power generation capacity of the model photovoltaic power station according to the monitoring data; and predicting the medium-and-long-term power generation capacity of the regional photovoltaic power station group according to the predicted medium-and-long-term power generation capacity of the model photovoltaic power station. In the method provided by the invention, the model photovoltaic power station is selected according to the monitoring data to predict the medium-and-long-term power generation capacity of the model photovoltaic power station, and the medium-and-long term generating capacity for the regional photovoltaic power station group is predicted by effective raise in the scale according to the predicted medium-and-long-term power generation capacity of the model photovoltaic power station, thereby providing the basis for the commissioning and overhaul of units in medium-terms, the arrangement of operation and maintenance plans and the optimization of the inter-plant scheduling. A basis is provided for the effective implementation of the cross-regional long-term electricity transaction.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation and distribution, in particular to a medium- and long-term power generation prediction method for a regional photovoltaic power station group.
