Distributed photovoltaic project spontaneous self-use comprehensive electricity price prediction method

Abstract

The invention relates to a distributed photovoltaic project spontaneous self-use comprehensive electricity price prediction method, and the method comprises the steps: predicting the hour-level generating capacity of a photovoltaic power station according to the historical irradiation data of a site selection place of the power station; obtaining power consumption load data of the power consumption enterprise, comparing the power consumption load with the photovoltaic power generation power in different time periods, and judging the consumption types in different time periods; and according tothe constructed model, measuring and calculating the enterprise consumption distributed photovoltaic power in different time periods, and finally obtaining the self-generation and self-use comprehensive electricity price of the enterprise. The problem that the spontaneous self-use electricity price cannot be well predicted in the previous distributed photovoltaic industry is solved. The prediction can help the distributed photovoltaic power station investment enterprises to more accurately evaluate the investment income condition of the distributed photovoltaic power station. And the earlier-stage investment income analysis and decision making of the distributed photovoltaic project are more scientific and effective.

Description

technical field [0001] The invention relates to a distributed photovoltaic project management technology, in particular to a distributed photovoltaic project self-generated integrated electricity price prediction method. Background technique [0002] With the rapid development of distributed photovoltaic industry in recent years, distributed photovoltaic has been accepted by more and more enterprises. Based on the economics of distributed projects and the latest policy requirements, the project of "spontaneous self-use and surplus electricity connected to the grid" has become the mainstream of the industrial and commercial distributed photovoltaic industry. "Spontaneous generation and self-use, surplus electricity connected to the grid" means that the electricity generated by the distributed photovoltaic power generation system is used by the roof owner first, and the excess electricity is fed into the grid. "Spontaneous generation and self-use, surplus electricity connecte...
