In this research, we focus on abnormal voltage profile on distribution feeder, distribution system instability, unstable operation of power converters of distributed generations (DGs) caused by their mutual interference and the system frequency deviation in distribution system into which a lot of rotating machines such as synchronous generator, generating facilities with power converters such as photovoltaic generation, a kind of wind power generation, microgas turbine generation and fuel cell and power electronics based power flow controllers such as FACTS devices will be connected. For solving the above problems maintaining the current power supply reliability and cost performance, new operation, control and planning methods of the distribution system were proposed.First, a new method to control abnormal voltage profile on a high-voltage feeder with a large penetration of photovoltaic generations and wind power generations by using FACTS devices was proposed and the control performan … More ces of some kinds of FACTS devices were compared from viewpoints of their locations and minimum required capacities.Second, in order to suppress the system frequency deviation caused by a large penetration of wind power generations, a large capacity of energy stored battery was proposed to be introduced to the grid. An effective method for evaluating the minimum required MW and MWh capacity for the appropriate frequency control was developed here.Third, an introduction of superconducting generator (SCG) into the distribution system, that is, replacement of the conventional synchronous generator by SCG in the distribution system was considered for stabilizing the system unstable phenomena originating from the rotating synchronous generator and the feeder voltage fluctuation.Last, digital type of three-phase instantaneous-valued network simulator for distribution system with a lot of distributed generations was developed and was used for off-line simulation of demand-supply control in micro-grid system. This simulator is helpful for analyzing unstable operation of DG converters caused by their mutual interference and for developing the stable operation method. Less

本研究主要针对配电馈线电压异常、配电系统不稳定、分布式电源变流器相互干扰引起的不稳定运行以及大量旋转机械等配电系统中的系统频率偏差等问题进行研究。作为同步发电机，将连接具有电力转换器的发电设施，例如光伏发电、一种风力发电、微型燃气轮机发电和燃料电池以及基于电力电子的潮流控制器（例如FACTS装置），以解决维持电流的上述问题。供电可靠性和首先，提出了一种利用FACTS装置控制光伏发电和风电渗透率较高的高压馈线电压异常的新方法。并从位置和最低需求容量的角度对几种FACTS装置的控制性能进行了比较。 其次，为了抑制风力发电的大量渗透、大容量的能源带来的系统频率偏差。建议使用存储电池这里开发了一种评估适当频率控制所需的最小 MW 和 MWh 容量的有效方法。第三，将超导发电机（SCG）引入配电系统，即替代传统发电机。考虑在配电系统中采用SCG同步发电机来稳定由于旋转同步发电机和馈线电压波动引起的系统不稳定现象。最后，数字式配电系统三相瞬时值网络模拟器开发了分布式发电系统，用于微电网系统中需求-供应控制的离线仿真，有助于解决分布式发电变流器由于相互干扰而导致的不稳定运行，并有助于开发稳定运行方法。
