【正文】 ed artificial intelligence [16] and has been widely used in other branches of puter science [17]. Problem solving is an area that many multiagentbased applications are concerned with. Liu et al. [18] introduced an application of distributed techniques for solving constraint satisfaction problem. Enlightened by multiagent system and PSO, this paper integrates multiagent system and PSO to form a multiagentbased PSO approach (MAPSO), for solving the reactive power optimization problem. In MAPSO, an agent represents a particle to PSO and a candidate solution to theoptimization problem. All agents live in a latticelike environment, with each agent fixed on a lattice point. In order to obtain optimal solution quickly, they pete and cooperate with their neighbors, and they can also use knowledge. Making use of these agent–agent interactions and evolution mechanism of PSO in a latticelike environment, the proposed method can find highquality solutions reliably with the faster convergence characteristics in a reasonably good putation time. MAPSO applied for optimal reactive power is evaluated on an IEEE 30bus power system and a practical 118bus power system. Simulation results show that the proposed approach converges to better solutions much faster than the earlier reported approaches. The rest of this paper is organized as follows: Section II describes mathematical formulation of optimal reactive power dispatch. Section III describesMAPSO in detail. Simulation results and parison with other approaches are given in Section IV. Finally, conclusions are presented in Section V. II. PROBLEM FORMULATION 10 The objective of the reactive power dispatch is to minimize the active power loss in the transmission work, which can be described as follows: )c os2( 22 ijjijNk iNk k l o s sQ VVVVgkPfEE????? ?? ??

The minimization of the above function is subject to a number of constraints: QijijijijNj jiDiGi NiBGVVPPO i ????? ?? )s i nc os( ?? (2) PQijijijijNj jiDiGi NiBGVV i ????? ?? )c oss i n(0 ??

In the most of the nonlinear optimization problems, the constraints are considered by generalizing the objective function using penalty terms. In the reactive power dispatch problem, the generator bus voltages and , the tap position of transformer, and the amount of the reactive power source installation are control variables which are selfconstrained. 教師評語 教師簽名：
