Improved Droop Control Strategy for Micro-grid Based on Virtual Synchronous Generator
摘要
Abstract
In allusion to smooth switching of operational state of the micro-grid under the role of traditional droop control, virtual moment of inertial equation is added in control loop by adopting thinking of virtual synchronous generator,which makes inverter of the micro-grid have similar dynamic performance with traditional synchronous generator and solves prob-lems of output of the inverter such as small impedance,small damp,and so on. Thus,frequency oscillation caused by sharp change of power is reduced. Meanwhile,a compensation control is added for increasing stability of the system under the con-dition of operational state switching. MATLAB software is used for simulation,which verifies validity of the designed im-proved droop control strategy for micro-grid.关键词
