Abstract

To make full use of distributed energy generation and satisfy the requirements of different loads on power quality, a micro-grid structure with consisting of double power supply, double fire wire and multiple loads is proposed, at the same time, the corresponding power supply controller and load controller are designed. This micro-grid structure realizes the two-way selection between municipal power generation and new energy for household load. It can not only fully apply new energy generation but also satisfy the requirements of household load on power quality, reduce the influence of harmonics and voltage fluctuations in the new energy grid on the distribution network, and improve the flexibility and reliability of the household power supply system.

Key words
