Benchmarking Flexible Electric Loads Scheduling Algorithms under Market Price Uncertainty

Because of increasing amounts of intermittent and distributed generators in power systems, many demand response programs have been developed to schedule flexible energy consumption. However, proper benchmarks for comparing these methods are lacking, especially when decisions are made based on information which is repeatedly updated. This paper presents a new benchmarking tool designed to bridge this gap. Surveys that classify flexibility planning algorithms were an input to define the benchmarking standards. The framework can be used for different objectives and under diverse conditions faced by electricity energy stakeholders interested in flexibility scheduling algorithms. It includes a simulation environment that captures the evolution of look--ahead information, which enables comparing online planning and scheduling algorithms. The benchmarking tool is used to test seven planning algorithms measuring their performance under uncertain market conditions. The results show the importance of online decision making, the influence of data quality on the algorithm performance, the benefit of using robust and stochastic programming approaches, and the necessity of trustworthy benchmarking.
