This function takes the n time domain samples (real or complex) and finds the psd by taking (fft/n)^2. The two sided spectrum is produced by shifting the psd The array freq provides the appropriate frequency values for plotting purposes. By taking 10*log10(psd/max(psd)) the psd is normalized values beow 60db are set equal to -60db

(1>分析低压微电网中逆变器输出阻抗特性，采用了虚拟阻抗的控制方法对逆变器输出阻抗进行构造，又从微电网本身特点考虑，构造逆变器的输出阻抗为阻性，使得Pv/QF的反下垂控制方法可以被合理使用。 (2>对逆变器功率外环进行小信号建模，分析当输出阻抗性质发生变化时系统(1 Analysis of low voltage microgrid inverter output impedance characteristics, the control method of virtual impedance of the structure on the output impedance of the inverter, and the characteristics of micro grid is considered, the output impedance of inverter structure for resistance, the Pv/QF control method of anti sag can be reasonable use. 2 of the inverter power outer loop small signal modeling, analysis the characteristics of output impedance changes the system)
