Abstract

Traditionally, optimal reactive power dispatch (ORPD) is a subset of optimal power flow (OPF) and can be achieved by controlling a number of control variables such as generator voltages, transformers’ trappings and compensation of reactive power to optimize specific objectives. ORPD is formulated as a non-linear constrained optimization problem with continuous and discrete variables. This paper presents a recently developed modified differential evolution (MDE) algorithm to solve ORPD problem by minimizing real power loss and total voltage deviation. To accelerate the convergence speed and to improve solution quality, the certain modification is incorporated in original differential evolution (DE) algorithm. The proposed MDE approached is implemented on the modified IEEE 30-bus test system. Results reveal primacy in terms of solution quality of the proposed MDE approach over original DE and other optimization techniques and affirm its potential to solve the ORPD problem.
