An electric power trading support system includes a demand prediction unit, a demand prediction error evaluation unit, a demand predicted value upward adjustment ratio (quantity) setting unit, a private power generation/power purchase ratio (quantities) setting unit, an optimization unit for evaluating optimum values of the demand predicted value upward adjustment ratio (quantity) and the self power generation/power purchase ratio (quantities) based on costs, and a display unit for displaying the optimum values evaluated by the optimization unit, maximizing profit to an electric power retailer by minimizing the cost for power generation and power purchase when the electric power retailer sells electric power by use of a private power generator and backup electric power purchased from an electric power company.

Electric power trading support system

In a control system equipped with a plurality of subsystems and a supervising subsystem for supervising these subsystems, a subgoal achievement performance is calculated by the subsystem using its own knowledge and its own condition with respect to a subgoal defined by the supervising subsystem, and the supervising subsystem controls a control system by utilizing the knowledge and conditions of the respective subsystems by applying a subgoal execution instruction to the subsystem based upon the calculation result. Since not only the knowledge but also the condition of the subsystems, proper controls can be realized in not only such a case that the supervising goal is directed to a static temporal aspect, but also such a case that the supervising goal contains a temporal element.
