A Distributed Droop Control Scheme for Islanded DC Microgrid Considering Operation Costs
摘要
Abstract
The novel economic droop control strategy with considering of factors like generation cost, efficiency, and emission penalty has effectively solved the problems brought by conventional droop controls, which mainly focuses on achieving proportional power sharing but not others. A distributed cost-based droop control strategy was proposed, and the optimal operation was achieved based on distributed consensus algorithm which would update the droop coefficient synchronously. The proposed distributed strategy has advantages of centralized control and autonomous control. Due to having no central controller, the robustness and flexibility of the control are increased significantly. A DC microgrid model including DGs with different operation costs was built based on Matlab/Simulink, and JADE (Java agent development framework) was used to develop distributed strategy. Then, the effectiveness of the control strategy was verified based on simulation. The influence of communication delay was analyzed at length, and the improved methods were proposed. In order to verify the "plug and play" capability, the scheme of adding nodes was designed and simulated.关键词
