摘要:

随着独立服务提供商从传统能源转向可再生能源,电力分配系统将面临日益显著的供应波动,由于风能和太阳能等可再生能源的不确定性和间歇性。这些发电波动,加上时间变化的电力消费需求和大规模电力分配网络规模,需要不仅设计实时去中心化功率分配算法,还要表征在快速变化的消费需求和发电容量下这些算法的有效性。本文提出在线去中心化双下降(OD3)功率分配算法,并确定在最坏情况下,观察到的社会福利和价格波动可以由发电容量和消费需求的波动解释多少。通过表征在线决策与最优决策之间的差异,分析OD3算法的收敛性质和性能保证。论文的理论结果通过使用真实数据的数值实验进行验证和说明。

英文摘要:

As independent service providers shift from conventional energy to renewable energy sources, the power distribution system will likely experience increasingly significant fluctuation in supply, given the uncertain and intermittent nature of renewable sources like wind and solar energy. These fluctuations in power generation, coupled with time-varying consumer demands of electricity and the massive scale of power distribution networks present the need to not only design real-time decentralized power allocation algorithms, but also characterize how effective they are given fast-changing consumer demands and power generation capacities. In this paper, we present an Online Decentralized Dual Descent (OD3) power allocation algorithm and determine (in the worst case) how much of observed social welfare and price volatility can be explained by fluctuations in generation capacity and consumer demand. Convergence properties and performance guarantees of the OD3 algorithm are analyzed by characterizing the difference between the online decision and the optimal decision. The theoretical results in the paper are validated and illustrated by numerical experiments using real data.
