随着更多可控能源和具有通信能力的响应负载被引入智能电网，能源管理正在成为未来电网系统的一个关键问题。本文提出了一种新颖的分布式方法，使用实时定价（RTP）和共识网络来处理可调度分布式发电机和响应负载下的智能电网中的能源管理，以最大化社会福利。在我们的算法中，每个分布式发电/用电单元根据当地能源价格决定其最佳发电/消耗水平，以在设备级别最大化其效益。然而，尽管发电和消费者单位有贪婪的行为，但当地零售商之间基于共识的价格协调推动整个系统的行为走向全球最优。我们算法的主要特点是计算和通信可扩展性以及信息隐私。
Energy management is becoming a crucial issue in the future power grid system as more controllable energy resources and responsive loads with communications abilities are being introduced into the smart grid. This paper proposes a novel distributed approach to deal with energy management in the smart grid under dispatchable distributed generators and responsive loads using real-time pricing (RTP) and consensus networks to maximize the social welfare. In our algorithm, each distributed generation/consumer unit, in response to the local price of energy, decides on its optimal power generation/ consumption level to maximize its benefit at the device level. However, the consensus-based coordination of price among local retailers drives the behavior of the overall system toward the global optimum, despite the greedy behavior of the generation and consumer units. The main features of our algorithm are computational and communicational scalability, as well as privacy of information.
