| Research Abstract |
In the electric power system included multiple entities, entities or players take the complicated economic action by which they are able to get maximum benefit. Operator of these power systems has to sustain the permissible level of power quality and has to realize physically the complicated transaction on the real power network. We have studied the safe realization of the competitive transactions in the normal state, the preventive action including the transaction curtailment for network line loading relief procedure in order to survive the predicted emergency state, the duty allocation among the entities for maintaining the reliability and the effect of the coalition behavior of entities to the reliability enhancement by the support of the Grand-in Aid for Scientific Research.
Studies include the followings : 1) Contribution of multiple entities on the line loading relief procedure and the improvement of system reliability. This study was reported at the CIGRE London Symposium on June 1999. 2) Feature extraction for controllable area of power flows depending on the phase shifter allocation. 3) A study on screening of electricity transaction path from the standpoint of dynamic stability. These topics appeared on the IEE Japan Periodicals, Transaction Section B in 1998 and 1999, respectively. 4) New reliability concept of the electric power system under the competitive circumstance, specially focused on the coalition behavior in the preventive or the emergency state. This study was reported at the PSAM5 Osaka Symposium on November 2000. 5) Analysis of the reliability collapse through the network stress followed by the complicated power flow because of selfish economic actions among the entities. 6) Solutions to sustain the reliability by the nodal price and the reliability must-run-generation. 7) Simulation study by using the client-server system established on the supported WS system.
