In this research, voltage control, over current mitigation, frequency control by centralized and autonomous control of distributed generators and quantitative verifications of their effects are carried out. Through computer simulations, etc., the following research results are found or learned.(1) Two autonomous control methods for distribution voltage control are developed. One is to control voltage of the same bus where distributed generators (DGs) are connected. The other controls several bus voltages in the neighboring area of DGs. Through computer simulation, it is found that the latter is better then the former.(2) Three phase load flow program is developed where three phase unbalance, lines to ground capacity and three phase transformer connections can be treated.(3) The optimal operation method of small scale co-generation system for home use is developed. By using the method, load leveling effects of DGs are verified.(4) The method by which power output of DGs based on renewable energy resources is leveled or smoothed by conventional DGs is developed. Validity of the method is verified by computer simulations.(5) Frequency control ability of DGs is tested by simulation through MATLAB. It is found that the frequency control ability of DGs is very limited, and it is difficult to expect much.The above research results are published by many papers shown in 11.

在这项研究中，电压控制，过电流缓解，频率控制的分布式发电机的集中和自主控制和定量验证其效果进行。通过计算机模拟等，发现或获知以下研究结果。(1)提出了两种配电网电压控制的自主控制方法。一种是控制分布式发电机（DG）连接的同一总线的电压。另一个控制DG相邻区域的几个总线电压。通过计算机仿真，发现后者优于前者。(2)开发了三相潮流程序，可处理三相不平衡、线路对地容量和三相Transformer接线。(3)提出了小型家用热电联产系统的优化运行方法。通过该方法，验证了分布式电源的负载均衡效果。(4)开发了基于可再生能源的DG的功率输出与传统DG持平或平滑的方法。计算机仿真验证了该方法的有效性。(5)通过MATLAB仿真验证了DG的频率控制能力。发现分布式发电的频率控制能力非常有限，很难有太大的期待，以上研究成果发表于11.
