Analysis of the Development of DC Distribution Network with Renewable Energy and Flexible Energy Storage

Abstract

In order to meet the increasing demand for DC load of electric vehicles, information equipment and semiconductor lighting systems in today's increasingly urbanized distribution networks, and to prevent the deterioration of environmental problem, a large number of intermittent, unstable renewable energy are integrated into the DC distribution network. According to the characteristics of renewable energy, the mixed energy storage mode can be used to realize the separation of power generation and electricity utilization in the space and time. It is reasonably planned to realize the safety, economy, high quality and reliability of the DC distribution in the future.
