摘要:
鉴于分布式电源的大量接入及其运行状态的变化会引起电网潮流和节点电压的改变、对电压跌落的暂态响应特性也会造成影响,文章以一个含分布式光伏和风电模拟单元的微电网为实际对象,建立分布式电源模型和网络模型,并采用牛顿—拉夫逊潮流算法进行仿真,实测数据与理论数据的偏差在3% 以内;调节微电网试验平台可控发电单元的输出功率,利用电网模拟器模拟电网电压跌落,研究了电压波动和低电压穿越等问题。仿真与试验测试结果表明,该微电网试验平台能为分布式发电潮流研究提供半实物仿真基础。
Abstract:
The access of a large number of distributed sources or the change of those sources’s operation status will cause power flow and node voltage change, and influence their own transient response feature of voltage drop. Therefore, a micro-grid which includes distributed photovoltaic and wind power simulation units was taken as an actual object. It established distributed generation model and network model, and performed simulation process by Newton-Raphson power flow algorithm. The error between the measured data and the theoretical data turned out to be less than 3%. Futhermore, it regulated output power of the controllable generation unit, and analyzed the voltage oscillation and lowvoltage ride-through based on grid-voltage drop simulated by grid simulator. Test results show that the platform can provide semi-physical simulation basis for the research on power flow in distributed generation system.
