Abstract

ABSTRACT In this paper, a new control method is proposed to regulate the critical load’s voltage at the nominal value for low-voltage microgrids. So that, without telecommunication communication, the impedance voltage drop of the connection between the distributed generation (DG) output to the point of common coupling (PCC) for the passing of reactive and active power will be compensated. Where the Q-V droop control method will be modified to adjust the voltage of critical load to the normal value. Also, the sharing of reactive and active powers is accurately based on the DG resources capacity between them. For distinct control of the reactive and active powers and accurately sharing them between sources from the virtual impedance used with control loops of current and voltage. Also, in this method, the circulating current between sources will be minimized. The proposed method to test its effectiveness was performed on two networks, one with two DG units and the other with four DG units. The simulation results show that the proposed method is effective.

基于负载电压控制提高孤岛微电网有功和无功功率的共享
本文提出了一种将低压微电网临界负载电压调节到标称值的新控制方法。这样,在没有电信通信的情况下,分布式发电(DG)输出到共耦合点(PCC)之间的连接为无功和有功功率的通过而产生的阻抗电压降将得到补偿。其中修改Q-V下垂控制方法,将临界负载电压调整到正常值。无功和有功功率的共享也准确地基于两者之间的DG资源容量。通过与电流和电压控制回路配合使用的虚拟阻抗,实现无功和有功功率的不同控制,并在电源之间准确地共享它们。此外,在这种方法中,源之间的循环电流将被最小化。在两个网络上进行了测试,一个网络有两个DG机组,另一个网络有四个DG机组。仿真结果表明,该方法是有效的。图形抽象
