A Tabu Search Based Method for Optimal Allocation of D-FACTS Devices in Distribution Systems

چکیده
This paper proposes a tabu search based method for optimal allocation of FACTS in distribution systems. Distributed generation is wildly spread to smooth operation and planning in power systems so that wind power generation units are connected to distribution systems. Although they contribute to the improvement of operation and planning in distribution systems, they often bring about difficulties that the existence of reverse power flows causes the voltage and frequency fluctuations due to uncertain generation output. In this paper, a new meta-heuristic optimization method is proposed to control the voltage deviations caused by wind power generation. It is necessary to determine the optimal allocation and the output variable of power controllers (D-FACTS) for uncertain wind power generation. This paper presents the Monte Carlo simulation method that determines the optimal allocation and the output variable of the controllers and evaluates the voltage security assessment in a probabilistic way. This paper is successfully applied to the IEEE 32-node distribution system.
