A Review on Eigen Analysis of Power System Using Parallel Computing

In this paper, a new parallel procedure is proposed to accelerate the solution of linear systems required by iterative Eigen analysis methods. Now days Eigen analysis of power systems is frequently used to study the effect and tune the response of existing controllers, to guide the design of new controllers. Recent developments in the area lead to the necessity of studying larger power system models, resulting from the interconnection of transmission. These models include new types of controls, mainly based on power electronic interfaces, which are expected to provide significant support in the future. The consequence is that the size and complexity of these models challenge the computational efficiency of existing Eigen analysis methods. In this paper, a procedure is proposed that uses domain decomposition and parallel computing methods, to accelerate the computation of Eigen values in a selected region of the complex plane with iterative Eigen analysis methods. The proposed algorithm is validated on a small transmission system and its performance is assessed on a large-scale combined transmission and distribution system.
