This paper discusses a power flow control mechanism for the “Open Electric Energy Network (OEEN)” which has been studied by the authors as a demand-side network suitable for a free market of electricity. The important concept of OEEN is that electric energy is treated like a packet of mail with the information about sender (power producer) and receiver (consumer). The control mechanism discussed in this paper is called “Electric Energy Router”, and which includes energy storage device. Electric Energy Router controls the storage device in such a way that the “electricity packet” reaches a specified consumer from a specified power producer autonomously and in the distributed manner. This paper shows that optimal control theory can be applied to determine the control action of Electric Energy Router. The obtained optimal control action minimizes the difference between consumer's load pattern and the Router's supply pattern under the inequality constraints of energy storage capacity, A numerical example is given in order to check the validity of optimal control theory application. Furthermore, in order to manufacture a small scale Electric Energy Router for experiment, its basic structure and power control performance are studied through the simulation studies.
