Abstract

The invention relates to a solar photovoltaic power generation system with an energy networking function. Solar photovoltaic power generation is applied in large scale in independent household systems in remote areas and power supply systems in centralized village power stations. As a main clear energy source, solar power generation has obvious advantages. The solar photovoltaic power generation system comprises a local area power grid power transmission unit and a plurality of household basic units connected with the local area power grid power transmission unit. Each household basic unit consists of a solar photovoltaic component, an intelligent control unit, a power carrier unit or controller area network (CAN) bus, a load equalization unit, a photovoltaic networked charging unit, a power sharing regulation unit, a local area energy source network unit, a DC / DC unit, a two-way DC / DC unit and a modular energy storage unit. The solar photovoltaic power generation system performs networking among households or electricity users to construct a local area energy source network, and a power regulation function is realized among the household basic units to realize energy source sharing.

Description

technical field [0001] The invention relates to the technical field of renewable clean energy, in particular to a solar photovoltaic power generation system with energy networking function. Background technique [0002] Solar photovoltaic power generation has been widely used in independent household systems in remote areas and power supply systems in centralized village power stations. As the main clean energy, the benefits of solar power generation are obvious. At present, the common solar power generation system is composed of solar photovoltaic modules, solar controllers, battery packs, loads and inverters (optional). Its solar modules and energy storage battery can only be used by this unit. Due to the high prices of solar modules and energy storage batteries, the cost of solar power generation is very high, which has become a major obstacle to the promotion and application of solar power generation. Contents of the invention [0003] The present invention provides ...
