Public interest in environment and site problems of utility's large scale power plants tend to encourage the effective use of small scale dispersed generation plants such as photovoltaic cell, cogeneration and fuel cell in metropolitan areas. Such dispersed plants generate a small amount of electric energy individually and the most of them would be owned by consumers. In addition, the quality and supply reliability of the generated electricity depend on each plant. If a lot of dispersed generation plants are interconnected with the utility's power network in metropolitan areas and the surplus electric energy can be supplied to the other consumers through the network, then it would be difficult to monitor and control the energy flow in the centralized manner which is adopted by the existing power utilities.In this study, a new method for electric power flow control is developed for overcoming the difficulties associated with the interconnection of dispersed generation plants. The major … More results obtained through the study are as follows.(1) A novel method of electric power flow control is developed which is based on electric energy storage and real time communication. The most important concept in the method is that the surplus electric energy generated by each dispersed plant is treated as a packet of electricity, and the information about sender (plant) and receiver (consumer) is attached to this packet as a tag. The concept makes it possible that electric energy can flow autonomously from the specified power plant to the specified consumers without the centralized monitoring and control of entire power flows. The packet of electricity is called "Electric Energy Packet"(2) In order to achieve the autonomous flow of Electric Energy Packet, a new device for power flow control is devised which consists of electric energy storage device and multi terminal AC-DC converters. The new device is called "Electric Energy Router".(3) The methods to determine the size and the way of power flow control action of Electric Energy Router are developed by applying queuing theory and optimal control theory.(4) A small scale prototype of Electric Energy Router is manufactured for trial.

公众对公用事业的大型发电厂的环境和场地问题的兴趣倾向于鼓励在大都市地区有效地使用小型分散发电厂，如光伏电池、热电联产和燃料电池。这种分散的发电厂单独产生少量的电能，其中大部分将由消费者拥有。此外，发电的质量和供应可靠性取决于每个工厂。在大都市地区，若有大量分散的发电厂与电力公司的电网互联，并将多余的电能通过电网供应给其他用户，则现有电力公司所采用的集中式能量流动监控将变得困难。开发了一种用于电力潮流控制的新方法，以克服与分散发电厂的互连相关联的困难。主要 ...更多信息 研究结果如下。(1)提出了一种基于电能存储和真实的实时通信的潮流控制新方法。该方法中最重要的概念是将每个分散的工厂产生的剩余电能视为电力包，并将有关发送者（工厂）和接收者（消费者）的信息作为标签附加到该包上。该概念使得电能可以自主地从指定的发电厂流向指定的用户，而无需对整个电力流进行集中监控和控制。（2）为了实现电能包的自主流动，设计了一种新的潮流控制装置，该装置由电能存储装置和多端AC-DC变换器组成。这种新设备被称为“电能路由器”。(3)应用排队论和最优控制理论，提出了确定电能路由器规模和潮流控制作用方式的方法。(4)制作了一台小型电能路由器样机进行试验。少
