Structure optimization of power system using Simulated Annealing Algorithm

The simulated annealing algorithm is used as an optimization technique to solve the problem of total investment cost optimization, subject to the reliability constraints. The problem of optimization of the structure of a power system where redundant elements are included in order to provide a desired level of reliability is known as Redundancy Optimization Problem. The problem is presented by multi-state series-parallel systems. System reliability is defined as the ability to satisfy consumer demand which is represented as a piecewise cumulative load curve. We supposed variation of the load cumulative demand curve null. A universal generating function technique is applied to evaluate system availability.
