An Optimization Model of HVDC Transmission System Reliability Improvement Measures Based on Cost-Benefit Analysis
With the continuous expansion of HVDC transmission system scale penetrating renewable energy, it is necessary to make an accurate investment decision considering HVDC transmission system reliability improvement measures. This paper proposes an optimization model using Life-Cycle Cost (LCC) theory for reliability improvement measures, and an optimization ranking algorithm based on marginal benefit. Firstly, the cost-benefit analysis of power system reliability based on LCC is established to evaluate the system reliability of the HVDC transmission system. Then, the reasonable reliability improvement measures are determined through cost-benefit analysis in order to improve the reliability. Finally, the method proposed in this paper is validated by case study. The results can provide scientific support for the reliability, economy and operation decisions of the HVDC transmission system.
