摘要
文章对高比例独立新能源微电网二次调压系统设计展开研究。选用高比例独立新能源微电网二次调压系统所需设备设计硬件;在软件设计中,设置微电网调压灵敏度矩阵,确定各因素对电压的影响程度,构建微电网电压控制空间进行区域划分,以此为基础实施自适应下垂控制一次调压,最后锁定输出功率实现微电网二次调压。测试结果表明,在加入高比例独立新能源微电网二次调压系统后,电压逐渐趋近并最终达到额定值,系统具有实际应用意义。
This paper studies the design of secondary voltage regulation system of high-proportion independent new energy microgrid.Select high proportion of independent new energy microgrid secondary voltage regulation system equipment design hardware;In the software design,the voltage regulation sensitivity matrix of the microgrid is set up to determine the influence of various factors on the voltage,and the voltage control space of the microgrid is constructed to divide the region.Based on this,the adaptive sag control of the primary voltage regulation is implemented,and the output power is locked to realize the secondary voltage regulation of the microgrid.The test results show that the voltage gradually approaches and finally reaches the rated value after adding the high-proportion independent new energy microgrid secondary voltage regulation system,which indicates that the system has practical application significance.
