Optimal reactive power dispatch based on particle swarm optimization and LP technique
Voltage stability enhancement is obtained by adjusting the control variables to nearer optimal solutions for the selected objective function. This paper presents the biological swarm behaviour of a bird flocking or fish schooling for solving the optimal reactive power dispatch (ORPD) problem using PSO algorithm. The main idea of this paper is to minimize the sum of the square of voltage deviations at load buses using fast decoupled load flow (FDLF) method and sensitivity parameters relating control and dependent variables. The on load tap changing transformers (OLTC) Generator exciters, Static VAR Compensators (SVC) are used as control variables for improvement of system parameters like voltage deviation (Ve) L index and real power loss. The effectiveness of the proposed method is demonstrated on IEEE New England 39 bus power system for near optimal solutions. The performance of the proposed method is compared with conventional optimization technique and presented for illustration purpose.
