摘要:

未来智能电网中小型分布式能源发电的出现导致了所谓的产消者,他们既能消费又能生产能源。通过利用可再生能源的本地发电,在高峰需求期间可以显著减少电力生产和供应系统的压力。然而,这也会给传统电厂带来挑战,当可再生能源下降时,电厂需要迅速提升出力。本文提出一个针对产消者的能源消费调度问题,以最小化系统的峰值爬升。通过求解集中优化问题可以获得最优调度。然而,由于隐私问题和电力系统的分布式拓扑,集中式设计在实践中难以实施。因此,我们提出分布式算法,利用交替方向乘数法(ADMM)高效解决集中问题,其中每个产消者独立调度其能源消费配置。仿真结果展示了所提算法的收敛性能以及模型在减少系统峰值爬升方面的能力。

英文摘要:

The arrival of small-scale distributed energy generation in the future smart grid has led to the emergence of so-called prosumers, who can both consume as well as produce energy. By using local generation from renewable energy resources, the stress on power generation and supply system can be significantly reduced during high demand periods. However, this also creates a significant challenge for conventional power plants that suddenly need to ramp up quickly when the renewable energy drops off. In this paper, we propose an energy consumption scheduling problem for prosumers to minimize the peak ramp of the system. The optimal schedule of prosumers can be obtained by solving the centralized optimization problem. However, due to the privacy concerns and the distributed topology of the power system, the centralized design is difficult to implement in practice. Therefore, we propose the distributed algorithms to efficiently solve the centralized problem using the alternating direction method of multiplier (ADMM), in which each prosumer independently schedules its energy consumption profile. The simulation results demonstrate the convergence performance of the proposed algorithms as well as the capability of our model in reducing the peak ramp of the system.
