GATS-based reactive power and voltage integrated control

In this paper, the necessity of reactive power and voltage integrated control is briefly formulated, and its design principles as well as the main functions are presented. Based on operational practice in power network and the characteristic of this system, the particular realization method of a hybrid GATS optimization strategy is proposed in the selection of PV node voltage, the construction of fitness function, the confirmation of crossover rate and mutation rate, the combination of TS and GA algorithm, etc so as to implement the counter-regulation of voltage, optimize the node voltage profile, avoid premature convergence and shorten the search time. Compared with simple genetic algorithm(SGA), the improved algorithm achieved satisfactory result in IEEE 118 node power system, the search time is shortened and optimization effect is better, which indicates the practicability of the hybrid GATS optimization strategy.
