Abstract

The DC collection system for wind farms serves as a critical component for power transmission, making its reliable operation paramount. Currently, research on the operational reliability of DC collection systems in wind farms remains largely confined to evaluation, with limited studies focused on enhancing reliability. This article introduces a Battery Energy Storage System (BESS) into the DC collection system from the perspective of improving reliability through the BESS. However, the introduction of a BESS significantly increases economic costs, with storage lifespan being a key factor affecting economic viability. To balance system reliability and BESS economics, this paper proposes a multi-objective configuration optimization method that accounts for the BESS lifespan, and employs the CRITIC-MARCOS integrated decision-making method to determine the optimal BESS configuration. Finally, the proposed method was validated in a 100 MW DC collection system for wind farms, offering valuable insights for BESS configuration schemes in such systems.
Keywords: DC collection; energy storage life; reliability evaluation; energy storage system configuration; multi-objective optimization; CRITIC-MARCOS DC collection; energy storage life; reliability evaluation; energy storage system configuration; multi-objective optimization; CRITIC-MARCOS
