A two-layered neighborhood tabu search-based approach to optimal allocation of D-FACTS in distribution systems

This paper proposes two-layered neighborhood tabu search for determining the optimal allocation and output of D-FACTS device in a distribution system with uncertain wind power generation. In recent years, wind power generation has been introduced into distribution systems for clean and inexhaustible distributed generation. However, a distribution system with wind power generation often encounters the reverse flow due to the uncertain output performance of wind power generation. As a result, the voltage variation may become much larger. In this paper, two-layered neighborhood tabu search is proposed to determine the optimal allocation and output of D-FACTS devices. To consider the uncertainty of wind power generation, this paper carries out Monte Carlo simulation to evaluate the probabilistic voltage assessment in the distribution system with uncertain wind power generation. The proposed method is successfully applied to a sample system. © 2006 Wiley Periodicals, Inc.
