| Abstract: | How to determine the optimum type of components to obtain the maximum benefit considering the cost and operational reliability is becoming an important issue in the HVDC system planning and design processes. Based on the cost-benefit principle, the model and algorithm of determining the optimum type of components in HVDC systems is proposed. Considering the investment, maintenance and outage costs, this problem was formulated as a nonlinear and discrete optimization model. An improved genetic algorithm with... |
