Optimal Planning of AC/DC hybrid system with Renewable Generations: An Expansion Planning Modle

摘要

Flexible AC/DC hybrid system is seen as a favorable option for the next generation Energy Internet, giving an innovative solution to address the problem of accommodating large-scale renewable energy. This paper formulates a coordinated planning model to get the best system configuration while uncertainty of renewable energy generations and control strategy of converter are both taken into account. A scenario construction method using joint probability is proposed in this paper, which effectively solves the modeling problem of multiple uncertainties in both generation and load. The calculation results of testing AC/DC hybrid system which show the economy and robustness of the planning scheme, can be improved by using the flexible controlling resource of converter which further proves that the AC/DC hybrid system can promote the consumption of integrated energy in the future.
