摘要：
The development of active distribution network (ADN) is an effective approach to the consumption of intermittent distributed generation. Based on control technology of ADN optimal operation, a control method of global centralized optimization and regional coordinated correction is proposed. In the long cycle, global optimization control is implemented and an optimal flow model based on semi-definite programming theory is developed to get minimum power loss by coordinated globally active and reactive power resources. In the short cycle, the network is divided into several controllable regions, and the coordinated correction control strategy for distributed generation, voltage reactive power equipment, and flexible load for tracking the regional optimal operation objective is proposed. The simulation example demonstrates that global optimization control is able to effectively reduce power loss while regional correction control will accurately track the global optimization objective, maintaining the network optimal state of operation from beginning to end. © 2015 State Grid Electric Power Research Institute Press.
