Engineering Reports, Volume 8, Issue 6, June 2026.Due to complex wind farm conditions, a coordinated control system was designed. It manages DC power surges during AC faults by temporarily storing excess energy and regulating voltages. This strategy optimizes unbalanced power and enables effective fault recovery, resulting in minimal voltage fluctuations and superior performance.
