| 摘 要： | 针对微电网中的分布式电源出力的间歇性导致微电网功率不稳定的问题,基于虚拟同步发电机(Virtual Synchronous Generator,VSG)技术的控制方法,建立VSG的数学模型,设计了一种基于电流、电压和功率控制的反馈控制器,提出了一种全新的VSG控制策略,实现分布式电源动态特性对微电网中有功功率和无功功率的均分控制。并通过Matlab/Simulink仿真,验证了所提控制算法的有效性。结果表明:该控制策略对抑制因新能源发电并网导致的电网波动、提高电能质量具有重要意义。

| Abstract: | Aiming at the problem of the intermittency of distributed generation lead to the micro-gridpower instability, establishes (virtual synchronous generator, VSG) mathematical model based on thecontrol method of VSG technology, designs a feedback controller based on current, voltage and powercontrol, puts forward a new-type VSG control strategy, realizes uniform distributing control for activepower and reactive power of micro- grid by controlling the dynamic characteristic of distributedgenerations (DGs), by Matlab/Simulink simulation, verifies the validity of the proposed controlalgorithm. The result shows that the control strategy has important significance to suppress fluctuationof new energy sources and to improve the quality of power energy. |
