A roof distributed photovoltaic power generation intelligent energy storage management system

Abstract

The invention discloses an intelligent energy storage management system for roof distributed photovoltaic power generation, including: a photovoltaic power generation module, an energy storage module, a load collection module, an energy storage information collection module, an environmental information collection module and a weather prediction module; In the prior art, the distributed small-scale photovoltaic power generation systems are integrated. Firstly, the power transmission between multiple small-scale photovoltaic power generation systems integrated in an area is carried out, so as to ensure that all energy storage units in the energy storage module can maintain good conditions. In addition, by transmitting the power of the power supply users to the power receiving users in priority, the number of power supply users is reduced, thereby reducing the frequency of each user's power transmission to the grid, thereby Reduce the frequency of power transmission between small-scale photovoltaic power plants and the grid for power transmission, which has the effect of improving the stability of the grid.

Description

technical field [0001] The invention belongs to the technical field of distributed energy management, and in particular relates to a roof distributed photovoltaic power generation intelligent energy storage management system. Background technique [0002] Distributed photovoltaic power generation refers to photovoltaic power generation facilities constructed near the user site, and the operation mode is characterized by self-consumption on the user side, excess electricity being connected to the Internet, and balanced adjustment in the power distribution system. During the construction of urban photovoltaic projects, due to space limitations, photovoltaic panels are mainly installed on the roof of buildings, so as to make full use of the roof space and also have the effect of heat insulation. Therefore, distributed photovoltaic power generation on the roof is Currently has a good room for development. [0003] However, in the prior art, rooftop distributed photovoltaic powe...
