摘要

光伏发电系统是微电网中最重要的微电源之一

但是其易受自然气候影响

输出功率具有波动性、随机性、间歇性

不易控制

需要配备储能设备平抑功率波动

因此光储微电网的功率控制方法亟待研究。文中基于动态阻抗匹配思想

结合中心差分方法

给出一种光伏发电最大功率点跟踪自寻优控制系统的技术方案

并在此基础上

提出了计及光伏发电系统最大功率跟踪工况的光储微电网功率协调控制方法

实现了微电网中光伏发电系统与储能系统的功率协调控制。最后

通过仿真实验验证了文中所提出的功率协调控制方法的正确性和可行性。

Abstract

Photovoltaic generation is one of the most important microsources in microgrid

but it is susceptible to natural climate. The output power is fluctuant

random

intermittent

difficult to control

and energy storage devices have to be equipped to restrain power fluctuations. So the power control methods in microgrid are badly in need of study. Based on the dynamic impedance matching

combined with the center difference method

a method of photovoltaic maximum power point tracking self-optimizing control system is provided. And based on dynamic impedance matching

a new method of the power coordinated control of photovoltaic/energy-storage system in microgrid under the photovoltaic maximum power point tracking condition is proposed

which achieve power coordinated control of photovoltaic and energy storage in microgrid. Finally

the simulation experiment proves the correctness and feasibility of the proposed control method.
