Research on Voltage Coordination Control of Various Reactive Power Compensation Devices

为了解决分布式电源(Distruted Generation,DG)并网造成功率骤降从而间接使得电压波动的问题,本文根据实际标准选出的多种合适的无功补偿装置进行功率补偿,并通过粒子群算法优化协调各个无功补偿装置使其达到最优状态,得到最小有功网损,使得电压能运行在可控范围之内。文章在IEEE33节点网络的基础上搭建了一个分布式电源并网的无功补偿测试网络作为仿真算例,仿真结果显示所提策略的可行性、有效性。

In order to solve the problem of power fluctuation caused by the sudden drop of power caused by the distributed power supply. In this paper, according to the actual standard selection of a variety of suitable reactive power compensation device for power compensation. Through the particle swarm optimization algorithm to coordi-nate the various reactive power compensation device to achieve the optimal state to get the minimum active loss. So that the voltage can run within the controllable range. On the basis of IEEE33 node network, a distributed power supply grid-connected reactive power compensation test network is built as a simulation example. The simulation results show the feasibility and validity of the proposed strategy.
