APPLICATION OF IMPROVED PARTICLE SWARM OPTIMIZATION TO INTEGRATED CONTROL OF VOLTAGE AND REACTIVE POWER

The necessity of applying the integrated control to reactive power and voltage is briefly described, and a brief introduction to the principles of particle swarm optimization (PSO) is given. According to the practical operation of power systems an improved PSO suitable to discrete variables is put forward, in which the global and partial algorithms are effectively combined, the problem to be solved is divided into sub-problems and the mutation operator is led in. Applying the improved PSO to the calculation of IEEE 14-bus system and practical 130-bus system respectively, the calculation results show that the optimization effect by the improved by PSO is better than by other artificial intelligent algorithms, so the practicability of the improved PSO is proved.
