- Abstract
- In this paper, model predictive control method is applied to improve output DC voltage dynamic characteristic of 3-level NPC AC/DC PWM converter for DC distribution using LCL filter. Generally, DC grid is applied to micro grid with renewable energy as photovoltaic, ESS. Renewable energy as photovoltaic causes transient state of DC bus voltage because input/output of energy is irregular due to irregular generating power of renewable energy. Transient state of DC bus voltage is required to be minimized for stable power supplying because most loads connected to DC grid require digital load which is sensitive to voltage fluctuation. Proposed control method improved transient state of DC bus voltage characteristic applying model predictive control AC/DC PWM converter for DC distribution using LCL filter. Proposed method is verified by simulation. © 2016 IEEE.
