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.

Operation of three-phase modular multilevel converter (MMC) with reduced number of arms
Conventional three-phase MMC consists of six-arms, each arm is controlled to generate unipolar voltage ranging from zero to Vdc where Vdc is the input DC voltage. Each arm voltage has two components (DC and AC components). In this work, the operation of MMC with reduced number of arms (four arms only), correspondingly reduced cost is presented.
