With the trend of digitalization, machine-learning techniques will be widely applied in the planning and operation of power systems. Traditionally, machine learning and decision-making models are independent. The objective of machine learning is usually based on statistical metrics while decision-making models usually aim at lower cost and higher reliability.
An underlying assumption here is that a more statistically accurate result generated by machine learning will guarantee more effective decision-making. However, recent research shows different results. For example, the forecasting error might have an asymmetric impact on the system operational cost. The clustering error may have a distributional influence on network expansion decisions. Therefore a series of objective-based machine learning models have been proposed to address specific objectives of power system decision making such as the cost-oriented forecasting model, the closed-loop clustering model and the reliability-based expansion model.
Supported by authors of these recent emerging papers, this panel will further explore how objective-based machine learning could support more effective planning and operation of low-carbon power systems. These are essential ingredients to smart decisions which will increase the operating efficiency of the system.
The panel will discuss the following topics: 1). Theory: What is the fundamental science of objective-based machine learning models? How are they compared to other decision-making approaches such as probabilistic models and uncertainty optimisations? 2). Techniques: What algorithm and data innovations are required to implement objective-based machine learning models? Could the models truly reflect the objectives of the system? In reality, when the data is limited, what is the practical value of this approach? Is there a practical approach to manage the data in real-time or is there an alternative rule-based/AI-based solution? 3). Applications: What are the potential applications of this approach to different sectors and tasks in generators, networks, customers and markets? How flexible is the approach when the system is of high uncertainty? How transferrable is the approach to different systems and markets?
