摘要:

随着分布式能源的激增以及由于计量基础设施的进步而存储的数据量的增加,电力系统操作中的能量管理需要分布式计算。在本文中,我们提出了一个完全分布式的交替方向乘法(ADMM)算法来解决分布式经济调度(ED)问题,其中的优化问题是完全分解的参与代理。在我们提出的框架中,每个代理估计的对偶变量和平均的总功率失配的网络使用动态平均共识,这取代了双更新器在传统的ADMM与分布式替代。与其他分布式ADMM不同,该方法不依赖于任何特定的假设,并捕捉实时需求变化。该算法通过对IEEE 30节点和300节点测试系统的太阳能光伏发电渗透的案例研究进行了成功验证。

英文摘要:

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.
