The clean energy sources are utilized extensively due to environment protection. There will be series of challenges for distribution system operation and control with the high penetration of distributed generation (DG) in near future. This paper highlights the control framework and optimizaiton approach for the coordination of source-net-load in active distribution system, which can realize the effective accommodation distributed renewable resources and secure and economic operation. It can solve the compatibility between distribution systems with distributed generation. Simulation results validate the effectiveness of the coordinated control technology for active distrbution system.
