Abstract

Abstract:

Considering large fluctuation of the output power of the system due to the randomness and intermittency of the stroke and photo primary power of the high-scale wind storage hybrid system,an optimal allocation strategy for the wind storage hybrid system was proposed.According to the definition of dimensionless reliability synthesis index of system allocation,load distribution and equipment utilization,the opportunity constraint planning is used to overcome the influence of wind power and PV output power uncertainty,and the improved NSGA-II algorithm is used to realize the optimal configuration of wind-photo-storage hybrid system capacity.Using PSCAD software to build the wind-photo-storage hybrid system model,the proposed method is compared with the NSGA-II algorithm for optimal configuration.The experimental results show that the proposed method can greatly improve the influence of wind-photovoltaic uncertainty on the output power of the system.

Key words: hybrid photovoltaic wind battery power system, capacity optimal allocation, reliability, chance constrained programming, NSGA-II
