Research of Low-Voltage Direct Current Distribution System in Rural Power Grid
Nowadays,with the energy revolution and the rapid development of rural economy,the contradiction between supply and demand of electricity in rural distribution networks is prominent.However,rural areas also contain a large amount of solar photovoltaic energy and other distributed clean energy.How to efficiently utilize these energy sources and improve the shortage of rural electricity requires research based on demand.Due to the fact that most distributed energy sources have direct current properties,low-voltage direct current distribution systems can be used to construct new energy supply system.Adopting power electronic adaptive control technology and combining it with practical needs to design a reasonable storage capacity,carefully studying the network topology and workflow of the direct current distribution system,and proposing corresponding countermeasures from the aspects of standards,cost-effectiveness,and load for actual problems that occur during system operation.The article analyzes the application of low-voltage direct current power grid and the characteristics of rural areas,and proposes an overall scheme for rural low-voltage direct current distribution system.
