  15. Ⅳ. Distributed Resource Interconnection Rules • Technical Criteria (To-be) • Connection Capacity (As-is) “DG can be interconnected to the grid if they meet the technical criteria” “DG can not be interconnected to the grid if their capacity over the capacity rules” SR have no technical barrier for connection with grid Power Smoothing Renewable Energy PQ Compensation (Smart Renewable Functions) Song– KR – RT.4c

  16. Ⅴ. Policy for DG Positive Impacts on Grid • Changed rule and policy • Exising rule and policy The existing rules and policy focus on the negative impacts of DG ☞ limit the connection capacity of DG ☞ hinder R&D activity and application of new technologies The changed rule intend to drive the positive impacts of DG ☞ Enlarge the connection capacity ☞ Utility have help form DG and also DG create new benefits “The Capacity Rules intend to alleviate the negative impacts of DG” “The changed rules and policy lead to the positive impacts of DG” SR can provide the ancillary service and also participate in the electric market Power Smoothing Renewable Energy PQ Compensation Intentional Islanding Energy Shifting Song– KR – RT.4c (Smart Renewable Functions)
