Improving the penetration level of PVs using DC link for residential buildings

• A common DC link for residential buildings allows customers to inject their surplus power without limitation.
• A common DC link for residential buildings prevents AC power quality issues.
• AC/DC network can be a the pathway to future DC network.

This paper proposes the use of a common DC link in residential buildings to allow customers to inject their surplus power that otherwise would be limited due to AC power quality violation. The surplus power can easily be transferred to other phases and feeders through common DC link in order to maintain the balance between generated power and load. PSCAD-EMTDC platform is used to simulate and study the proposed approach. This paper suggests that this structure can be a pathway to the future DC power systems.
