| 摘要: |
| 提出了一种线性分布式电源功率分配方案，在微电网孤网运行时可节约总的发电成本。基于(分布式电源)各自的平均发电成本，通过调整分布式电源下垂率实现成本的节约。与现有的基于非线性成本下垂策略相比，所提方案使用下垂曲线，在减少总成本方面取得了良好的性能。该方案以可调度及不可调度下垂控制的分布式电源微网进行了实验。实验结果证明了在不同的运行情况下，所提方案具有高效和良好的特性。 |

| Abstract: |
| This paper presents a linear power sharing scheme for distributed generators (DGs) to save the overall total generation cost (TGC) in an autonomous micro-grid. The cost saving is realized by tuning the droop gradients of DGs based on their respective mean generation costs. Compared with the existing non-linear cost-based droop schemes, the proposed scheme uses linear droop curve and achieves better performance in TGC reduction. The proposed scheme has been tested experimentally for the micro-grid, first with all dispatchable droop controlled DGs and then with non-dispatchable DG included. Experimental results have demonstrated the good performance and effectiveness of the proposed scheme under different operating conditions. |
