摘要： PROBLEM TO BE SOLVED: To provide a power demand prediction system capable of improving the prediction accuracy. SOLUTION: Respective customers 7a to 7n are notified of predicted individual power usage of every predetermined time of a particular day. An enterprise-side processor 2 compares the estimated individual power usage with actual individual power usage, and discounts power charge when the estimated individual power usage is approximately the same as an actual one. This enables power prediction processing portions 19a to 19n to utilize high-reliability prediction methods for power usage unique to the respective customers 7a to 7n. Furthermore, PPS enterprise 1 can calculate the predicted total power usage by using high reliability predicted individual power usage, and can bring a reservation to a power producer 3 close to the actual power usage of the respective customers. Thus, efficient power supply and demand control can be attained. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To overcome the problem in the operation allocation when the stability calculation of a power system is performed by a plurality of computers, which are caused by the fact that there is a case where the optimal operation allocation can not be performed due to waiting for an operation start case or for a high-order case by the series operation, or unavailability of the past results.SOLUTION: In a method for allocating the operation allocation, the number of operation processes is changed to calculate the operation allocation while the total operation time becomes the shortest. Moreover, the correction in the failure case allocation is performed based on results obtained from an operation device, and the priority of the selection index is increased when a state in the system is changed. The stability calculation of the power system is performed by the described optimal operation allocation at high speed.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for determining the stability of a power system which can materialize an appropriate countermeasure for stabilization even if the state of the target system changes greatly in a short while. SOLUTION: A power circuit stabilizing system is equipped with a circuit severity determining device 100 which is equipped with a severity index-value computing means 104 using on-line data related to the state of an electric system, and a circuit monitoring system 110 which changes the facility within the circuit against the fault of the circuit, based on the instruction. The circuit severity determining device 100 performs the state simulation of the electric circuit, for a short while (for example, a second) after occurrence of a fault. From the results, it gets a first index-value Ke being the maximum value of increasing rate based on the state before occurrence of the fault of the kinetic energy of a generator, and a second index-value KE being the maximum value of an integral value of the increasing rate. It selects the assumed fault of an unstable electric circuit, using these index-values, and gets the severity of the circuits and ranks them. COPYRIGHT: (C)2008,JPO&INPIT
