Basic Study on Flexible, Reliable and Intelligent Electrical Energy Delivery System

1. 为了实现FRIENDS，有必要对质量控制中心的内部结构和功能进行研究。因此，本研究建立了QCC所完成的许多功能，并提出了QCC在骨架水平上的许多结构。在此基础上，本研究提出了一些详细的QCC模型，可以为电力用户提供非捆绑的电能质量服务。本研究利用EMTDC.2电瞬态分析程序，从非捆绑电能质量服务的角度，模拟了一个拟议模型的电瞬态行为。在这项研究中，已试图通过开发一个计算机模型来估计“未捆绑”的最终用途能源需求，该模型模拟人们的活动和住宅中电器的使用。这种计算机模拟模型的原型已经开发出来。日本广播协会（NHK）进行的调查结果已被用作模型输入之一。通过与实际测量数据的比较，验证了模型的准确性。它可以用来将总电力需求分成两到三类，并根据不同的质量水平来估计它们在一天中的模式。此外，还对QCC的电路结构进行了研究。提出了一种子周期转换开关的控制方案，并通过实验进行了验证。提出了一种三相四线配电系统，并通过仿真成功地验证了其基本特性。为了实现最优的网络配置和系统灵活的交换操作，本文提出了以下两种算法。(1)从供电可靠性的角度出发，考虑分散型发电机组，提出了用禁忌搜索法确定friend最优网络配置的算法。(2)提出了一种确定给定运行状态下最优网络的算法，该算法可实现双故障情况下的不间断供电。进一步，结合上述算法，完成了考虑供电可靠性和故障状态运行的FRIENDS最小成本配置确定算法。对friend的需求侧前景进行了研究。从消费者的角度来看，FRIENDS的特点可以概括为“多菜单服务”。多菜单服务可以包括多供应商服务以及多质量服务。通过FRIENDS提供的多供应商服务，有可能使竞争激烈的电力市场活跃起来。本文通过建立消费者行为模型对电力市场进行分析，得出应设置轮转收费，以加剧电力公司之间的价格竞争。少

1. In order to realize FRIENDS, it is necessary to investigate interior structures and functions of Qualify Control Center (QCC). Thus, this study established many functions which are accomplished by QCC and proposed many structures of QCC in skeleton level. Further, this study proposed some detailed QCC models which can play unbundled power quality services to power customer. This study simulated electric transient behavior to a proposed model from a viewpoint of unbundled power quality services using electric transients analysis program : EMTDC.2. In this study, attempts have been made to estimate the "unbundled" end-use energy demands by developing a computer model which simulates the activities of the people and the use of electric appliances in residential houses. A prototype of such a computer simulation model has been developed. The results of the survey carried out by Nippon Broadcasting Association (NHK) has been used as one of the model inputs. The outputs of the model have b … More een compared with the actual measurement data and the accuracy of the model has been confirmed. It can be used to unbundle the total electric power demand into two or three categories with different levels of quality, and also to estimate their patterns over the day.Further, investigations with regard to the circuit structure of QCC have been carried out. A control scheme of subcycle transfer switches has been proposed and verified by experiments. Also a 3 phase 4 wire distribution system have been proposed and its fundamental characteristics has been successfully verified by simulation.3. The following two algorithms are developed for the optimal network configuration and for the flexible switching operation of the system.(1) An algorithm to determine the optimal network configuration of FRIENDS by TABU search method is developed from a view point of supply reliability through taking dispersed-type generators into account.(2) An algorithm to determine the optimal network for a given operational state is developed by which uninterrupted power supply even in a double fault situation can be realized.Further, by combining the above algorithms, an algorithm to determine the minimum cost configuration of FRIENDS is completed in which supply reliability and fault state operation is taken into account.4. The demand side prospect of the FRIENDS has been studied. From the viewpoint of consumers, the characteristic of the FRIENDS is summarized as the "multiple menu service." The multiple menu service may include the multiple supplier service as well as the multiple quality service. Through the multiple supplier service provided by FRIENDS, it is probable that the competitive power market is made active. In this study, the consumer behavior model is developed for the analysis of the power market, It is obtained that the wheeling charge should be set so that the price competition between IPPs is intensified.
