Abstract

The invention discloses a prediction method for the spontaneous and self-use comprehensive electricity price of a distributed photovoltaic power station, and related assemblies. The method comprises the steps: determining a power time function P(t) of a distributed photovoltaic power station; carrying out definite integral calculation on the power time function to calculate a daily electricity generating capacity time function W(t); predicting to acquire daily average electricity generating capacity, and calculating a peak power a; calculating the theoretical electricity generating capacity ofthe distributed photovoltaic power station in each specified time period and the average electricity consumption corresponding to the specified time period; and multiplying the self-use electricity generating capacity of each time period by the electricity price of the corresponding time period, multiplying the on-grid electricity generating capacity by the local benchmark electricity price, andperforming comprehensive statistics to acquire the comprehensive electricity price of the self-use mode of the distributed photovoltaic power station. According to the embodiment of the invention, theoutput power change of the photovoltaic power generation along with the change of the sunlight intensity is fully considered, and the factors influencing the spontaneous and self-use comprehensive electricity price are comprehensively considered, so that the accuracy of the prediction result is high.

Description

technical field [0001] The invention relates to the field of distributed photovoltaic technology, in particular to a method for predicting comprehensive electricity prices for self-generated self-use of distributed photovoltaic power plants and related components. Background technique [0002] Distributed photovoltaic power plants refer to photovoltaic power generation facilities built near user sites, whose operation mode is characterized by self-use on the user side, surplus electricity connected to the grid, and balanced adjustment in the power distribution system. Distributed photovoltaic power generation follows the principles of adapting measures to local conditions, clean and efficient, decentralized layout, and nearby utilization. It can not only effectively increase the power generation of photovoltaic power plants of the same scale, but also effectively solve the problem of power loss during boosting and long-distance transportation. [0003] In the design stage of...
