论文摘要
随着分布式能源资源的扩散以及由于计量基础架构的进步而存储的数据量，电力系统操作中的能源管理需要分布式计算。在本文中，我们提出了一种完全分布的乘数（ADMM）算法的交替方向方法来解决分布式经济调度（ED）问题，其中优化问题在参与者之间完全分解。在我们提出的框架中，每个代理使用动态平均共识估算网络的二变量和总功率不匹配的平均值，这用分布式替代方案代替了传统ADMM中的双重更新。与其他分布式ADMM不同，所提出的方法不依赖任何特定的假设，而是捕获实时需求变化。该算法通过太阳能光伏渗透的IEEE 30总线和300个总线测试系统的案例研究成功验证。
With the proliferation of distributed energy resources and the volume of data stored due to advancement in metering infrastructure, energy management in power system operation needs distributed computing. In this paper, we propose a fully distributed Alternating Direction Method of Multipliers (ADMM) algorithm to solve the distributed economic dispatch (ED) problem, where the optimization problem is fully decomposed between participating agents. In our proposed framework, each agent estimates the dual variable and the average of the total power mismatch of the network using dynamic average consensus, which replaces the dual updater in the traditional ADMM with a distributed alternative. Unlike other distributed ADMM, the proposed method does not rely on any specific assumption and captures the real-time demand change. The algorithm is validated successfully via case studies for IEEE 30-bus and 300-bus test systems with the penetration of solar photovoltaic.
