Reinforcement learning in sustainable energy and electric systems: a survey
یادگیری تقویتی در سیستم های انرژی پایدار و الکتریکی: یک نظرسنجی-2020
The dynamic nature of sustainable energy and electric systems can vary significantly along with the en- vironment and load change, and they represent the features of multivariate, high complexity and uncer- tainty of the nonlinear system. Moreover, the integration of intermittent renewable energy sources and energy consumption behaviours of households introduce more uncertainty into sustainable energy and electric systems. The operation, control and decision-making in such an environment definitely require increasing intelligence and flexibility in the control and optimization to ensure the quality of service of sustainable energy and electric systems. Reinforcement learning is a wide class of optimal control strate- gies that uses estimating value functions from experience, simulation, or search to learn in highly dy- namic, stochastic environment. The interactive context enables reinforcement learning to develop strong learning ability and high adaptability. Reinforcement learning does not require the use of the model of system dynamics, which makes it suitable for sustainable energy and electric systems with complex non- linearity and uncertainty. The use of reinforcement learning in sustainable energy and electric systems will certainly change the traditional energy utilization mode and bring more intelligence into the system. In this survey, an overview of reinforcement learning, the demand for reinforcement learning in sustain- able energy and electric systems, reinforcement learning applications in sustainable energy and electric systems, and future challenges and opportunities will be explicitly addressed.
