| 摘 要： | 将分布式电源以微网的形式并入配电系统中,研究其在能量高渗透情况下对配电网的影响。研究结果表明,在变功率输出控制模式下,含微网的配电系统将可能改变整个输电网的能量分布,因此有必要对输电网运行进行动态优化。考虑到实际优化中电容器组和可调变压器分接头的调节操作受一定限制,故采用了分时段解耦的简化策略,结合人工智能优化算法对电网进行了动态无功优化。此外,相关结果表明,对接入微网的配电网进行合理的无功就地补偿,可有效地降低系统网损,提高电网运行经济性。

| Abstract: | The distributed generation with maximum utilization was integrated to the distribution net-work in the shape of micro-grid,which was used to study the effects of micro-grid to the distribution network.The simulation results showed that the integration of distribution system with micro-grids un-der the control mode of variable power would change the energy distribution of the whole transmission.It is necessary to optimize the transmission network.Considered the action times of capacitor banks and transformer... |
