Abstract：

Recently,with the development of micro-grid,micro-grid system is expected to play an active role in improving power quality,stability and reliability of power grid.The grid-connected inverters are the key devices in micro-grid and extensively concerned in the world.This paper presents the major effects and typical topological structures of grid inverters-connected based on micro-grid in power grid.Analysis and comparisons of various inverting control strategies are carried out,several technical problems and relevant solutions related to synchronous phase lock technique and anti-islanding detection are also briefly introduced.The prospective inverting techniques should be the compound and complex control systems by combination of different control strategies,with active power transfer,inactive power regulation,harmonic suppression and fault detection simultaneously achieved.

Key Words： micro-grid;grid-connected inverter;control strategy;phase lock technique;anti-islanding
