การวางแผนและปฏิบัติการระบบไฟฟ้ากาลังในสภาวะฉุกเฉิน

This thesis presents an application of particle swarm optimization technique (PSO) to optimal economic dispatch analysis in power system with contingency criteria for management power system operation cost power loss and bus voltage. The objective of optimal economic dispatch for contingency in power system compared with the results of analysis power system in normal case. The study result show that when contingency occur in power system operation cost are rising. In the other hand system stability are decrease.
