Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Low-voltage ride-through (LVRT) requirements demand wind-por plants to remain connected to the network in presence of grid-voltage dips. Most dips present positive-, negative-, and zero-sequence components. Hence, regulators based on symmetrical components are ll suited to control grid-connected converters. A neutral-point-clamped topology has been considered as an active front end of a distributed por-generation system, following the trend of increasing por and voltage levels in wind-por systems. Three different current controllers based on symmetrical components and linear quadratic regulator have been considered. The performance of each controller is evaluated on LVRT requirement fulfillment, grid-current balancing, maximum grid-current value control, and oscillating por flow. Simulation and experimental results show that all three controllers meet LVRT requirements, although different system performance is found for each control approach. Therefore, controller selection depends on the system constraints and the type of preferred performance features.
