AN APPLICATION OF TLBO ALGORITHM FOR THE VOLTAGE STABILITY IMPROVEMENT BY MW-GENERATION RESCHEDULING.

Engineering

This paper presents Georschgorin's theorem a new approach method of accessing voltage stability and an application of TLBO optimization method for voltage stability improvement by MW-generation rescheduling. TLBO-teaching learning based optimization method is used for the parameters optimization of load flow Jacobean matrix. This method is based on the Teacher's influence on the learners.Optimal solution based generator rescheduling is performed for energy management during congestion by applying TLBO method for optimization process.Optimal energy transmission and its consumption is big issue in electric power systems as large amount of electricity cannot be stored in its electrical form. In deregulated power system, the transmission lines are overloaded. Congestion is not acceptable as it increases the energy price and threatens system reliability and security. The Georgeoschrin’s theorem is presented to trace the eigen values for power system voltage stability analysis. The theorem will gives the information regarding inclusion of matrix eigen values. Numerical analysis of IEEE 30-bus system is presented to provide evidence of the performance of the power system under critical loading. The presented algorithm takes less computational time to achieve their optimal MW rescheduling when compared with JAYA optimization method.
