Abstract

The invention provides an independent microgrid photovoltaic output power prediction method. In consideration of the problems that when an existing photovoltaic prediction algorithm model training set is selected, weather types are classified indistinctly and differences exist in the data at the same time of different dates of the same weather type, a selection method based on similar time is provided, and the errors caused by differences existing in the same time of different dates of a similar day in a traditional prediction method is avoided. The invention further provides an independent microgrid energy regulation method. Based on a current running state of a microgrid, the energy regulation method conducts optimal operation on a microgrid running device, a reserve power supply bidding model is built, an optimal reserve power supply combination which needs to be put into use at the current dispatching moment is obtained through solving the reserve power supply bidding model by means of an intelligent optimization algorithm, and therefore it is avoided that power supply is delayed since a reserve power supply which is needed to outputting power at the next dispatching moment has a planned time of starting running, so the power supply reliability of an independent microgrid is guaranteed and the economic operation is achieved at the same time.

Description

technical field [0001] The invention relates to the technical field of micro-grids, in particular to a photovoltaic output power prediction method and an energy regulation method of an independent micro-grid. Background technique [0002] With the development of science and technology and social economy, the advancement of science and technology is affecting the social economy and changing the field of microgrid technology. In the field of micro-grid technology, especially the development of independent micro-grid photovoltaic output power prediction and independent micro-grid energy regulation and management technology has a profound impact on micro-grid technology. [0003] At present, in the actual engineering application of microgrid energy management, for photovoltaic forecasting, when it is necessary to predict the photovoltaic power at a certain moment of the forecast day, the mean value of the training data source of the photovoltaic forecasting algorithm model at th...
