分布式能源交易:多微电网案例

Distributed Energy Trading: The Multiple-Microgrid Case

David Gregoratti, Javier Matamoros

摘要:

针对孤岛微网间的能量交易问题,提出了一种分布式凸优化框架。更具体地说,该问题由几个孤岛的微电网,通过任意拓扑结构交换能量流。由于可扩展性问题,为了保障本地信息的费用函数,提出了一种基于子梯度的成本最小化算法,收敛到最优解在一个实际的迭代次数和有限的通信开销。此外,这种方法允许一个非常直观的经济学解释,解释算法迭代的“供需模型”和“市场出清”。数值结果给出的收敛速度的算法和不同的网络拓扑结构所达到的成本。

英文摘要:

In this paper, a distributed convex optimization framework is developed for energy trading between islanded microgrids. More specifically, the problem consists of several islanded microgrids that exchange energy flows by means of an arbitrary topology. Due to scalability issues and in order to safeguard local information on cost functions, a subgradient-based cost minimization algorithm is proposed that converges to the optimal solution in a practical number of iterations and with a limited communication overhead. Furthermore, this approach allows for a very intuitive economics interpretation that explains the algorithm iterations in terms of "supply--demand model" and "market clearing". Numerical results are given in terms of convergence rate of the algorithm and attained costs for different network topologies.
