Abstract:
It is a problem to be solved to provide Electric power control systems and methods which do not require one-to-one communications in both directions, in which the communications traffic does not rapidly increase even if the number of electric power consumption elements increases and which have good expandability. In addition, it is also a problem to be solved to provide information transfer capability control systems and methods which can be worked by the similar principles. In over to solve the problems, information representing an indication value for adjusting total consumed electric power which is a function of the difference between a current value and a reference value of the total consumed electric power in the group is transmitted by broadcast. Respective electric power consumed elements included in the group receive the information, and calculate, independently and in parallel, their own update values for consumed electric power by an operation using their own degrees of priorities and the indication value for adjusting total consumed electric power, and control their own consumed electric powers based on this. Information transfer capabilities can be controlled by the similar principle.
