本程序对CBF和mvm算法进行了DOA估计,发现MVM算法要优于CBF算法。(This procedure of CBF and mvm DOA estimation algorithms and found that MVM algorithm is superior to CBF algorithm.)

说明：  给图片添加了正弦噪声，利用MATLAB源代码消除噪声。(Sine was added to the image noise, using MATLAB source code to eliminate noise.)

说明：  文档中的matlab源代码主要是针对单回路液位控制系统的PID控制实现，内有simulink原理图(Matlab source code in the document is mainly for single-loop PID control of water level control system to achieve, within the simulink diagram)

光伏电池板和Boost电路的系统模型，自己仿真时变下步长即可(Boost circuit photovoltaic panels and the system model, its simulation can be time-varying step size under)

when SNR is high , 1st sample estimator provides good estimate of A. it has no noise effect . so we don’t need averaging effect to reduce noise when SNR is high. However variance is still low in sample mean estimator which shows that in reality ,sample mean is good estimator than 1st sample estimator. So, for high SNR, we do not need to reduce the effect of noise by averaging. or we can say that for high SNR let say >1000 , 1st sample estimator got reduced noise. But as for as variance is concerned , the sample mean has low variance for high SNR as well.

With the increasing penetration of renewable energies as distributed generation (DG) in smart grid scheme, technical problems arise in both distribution and transmission system level. Undesirable voltage is the main problem for connection of DGs in distribution systems while excessive reactive power demand transmission system is the major concern for Transmission System Operators. The low power generation capacity of DER (Distributed Energy Resources) has motivated the need for integration of different types of DERs and loads in the form of micro-grid to enhance the power generation capacity, reliability and marketability of dispersed type of micro-sources [12, 13]. Current harmonics and Reactive power consumption are the two power quality issues that are addressed in this thesis
