Cost-Benefit Analysis (CBA) is an essential tool for economic decision-making, providing a systematic way to evaluate the financial value of projects. It employs mathematical techniques to quantify benefits and costs, enabling decision-makers to compare various options. By translating potential gains and expenses into monetary values, CBA identifies projects that yield the highest net benefits.

This paper proposes a low-voltage ridethrough (LVRT) capability for a doubly-fed induction generator (DFIG) wind turbine (WT) system. With the proposed method, series grid-side converter (SGSC) in which its DC-side connected at the DC bus of the back-toback converters and its AC-side connected in series with line through transformer have been applied, enables to compensate a voltage response of the system during the grid faults and to reduce the capital cost.
