论文摘要
本文研究了一组具有微燃料电池组合热量和动力系统的住宅中的最佳能源管理。为了提高这种当地社区的自给自足和韧性，提出了住宅之间的点对点能源交易系统，在该系统中，可以将在其额定功率下运行的燃料电池发出的产出能力可以将其出售给已经达到其额定产量的人，但仍然缺乏权力。由于功率和热效率对燃料电池输出功率的非线性依赖性，因此来自此最佳点对点能源交易系统的优化问题是非凸面。因此，提出了一种线性化方法来启用问题。因此，引入了分布式ADMM方法，以在每个住宅中并行解决共透的优化问题。然后提出了基于现实的电消耗数据的六个住宅的案例研究，以证明P2P能源交易系统的拟议方法性能和积极影响。更具体地说，所提出的分布式ADMM方法在收敛性方面相当快，并且与系统尺寸相关。此外，P2P电力交易系统有助于以更高的效率运行燃料电池，并增加此类住宅的自给自足。
This paper studies the optimal energy management in a group of dwellings having micro fuel cell combined heat and power systems. To increase the self-sufficiency and resilience of such local community, a peer-to-peer energy trading system between dwellings is proposed in which output powers from fuel cells working under their rated powers can be sold to those already reach their rated outputs but still lack powers. The arising optimization problem from this optimal peer-to-peer energy trading system is non-convex due to the nonlinear dependence of power and heat efficiencies on fuel cell output power. Therefore, a linearization method is proposed to convexify the problem. Consequently, a distributed ADMM approach is introduced to solve the convexified optimization problem in parallel at each dwelling. A case study for a group of six dwellings based on realistic electric consumption data is then presented to demonstrate the proposed approach performance and positive impacts of the P2P energy trading system. More specifically, the proposed distributed ADMM approach is reasonably fast in convergence and is scalable well with system size. In addition, P2P electricity trading system helps operate fuel cells at a higher efficiency and increase the self-sufficiency of such dwellings.
