所谓下垂控制就是选择与传统发电机相似的频率一次下垂特性曲线（Droop Character）作为微源的控制方式，即分别通过P/f下垂控制和Q/V下垂控制来获取稳定的频率和电压，这种控制方法对微网中的微源输出的有功功率和无功功率分别进行控制，无需机组间的通信协调，实现了微源即插即用和对等控制的目标，保证了孤岛下微电网内电力平衡和频率的统一，具有简单可靠的特点。(The so-called droop control is to select the frequency droop characte

该仿真模型基于重复控制算法，对滤波器的并网控制进行了详细的仿真，方便熟悉该算法的工作原理及逆变器的工作原理。 (The simulation model is based on the repetitive control algorithm, and the grid-connected control of the inverter is simulated in detail, which is convenient to familiarize with the working pri

光伏并网逆变器SIMULINK仿真程序，采用双闭环PI调节，并且加入重复控制(The Simulink simulation program of photovoltaic grid connected inverter adopts double closed loop PI regulation and adds repetitive control)

无网格法在数值计算中不需要生成网格，而是按照一些任意分布的坐标点构造插值函数离散控制方程，就可方便地模拟各种复杂形状的流场。该法大致可分成两类：一类是以Lagrange方法为基础的粒子法（Particle method），如光滑粒子流体动力学（Smoothed particle hydrodynamics，简称SPH）法，和在其基础上发展的运动粒子半隐式（Moving－particle semi－implicit，简称MPS）法等；另一类是以Euler方法为基础的无格子法（Gridless me

A single phase grid connected with a photovoltaic (PV) power system that will provide high voltage gain with state model analysis for the control of the system has been presented. First the photovoltaic system is designed and simulated using MATLAB
