Power Systems Stability Control : Reinforcement Learning Framework Damien Ernst, Member, IEEE, Mevludin Glavic, and Louis Wehenkel, Member, IEEE Abstract—In this paper we explore how a computational approach to learning from interactions, called Reinforcement Learning (RL), can be applied to control power systems. As many control problems are best solved with continuous state and control signals, a continuous reinforcement learning algorithm is then developed and applied to a simulated control problem involving the refinement of a PI controller for the control of a simple plant. stream Keywords: Electric power system, reinforcement learning, control, decision. The resulting controllers can pose implementation challenges, such as the When formulated as a Reinforcement Learning (RL) problem, the control of stormwater systems can be fully described by an agent and environment . complex controllers. By combining optimal -- a principled way of decision-making and control, with reinforcement learning for control designs, we are tackling various challenges arising in robotic systems. Since classical controller design is, in general, a demanding job, this area constitutes a highly attractive domain for the application of learning approaches—in particular, reinforcement learning (RL) methods. The environment represents an urban stormwater system and the agent represents the entity controlling the system. Web browsers do not support MATLAB commands. In several research projects, we investigate data-driven approaches for optimal and robust control, with applications e.g. These systems can be self-taught without intervention from an expert Reinforcement Learning Using Neural Networks, with Applications to Motor Control, dissertation by Remi Coulom that nicely presents continuous state, action, and time reinforcement learning. [6] MLC comprises, for instance, neural network control, genetic algorithm based control, genetic programming control, reinforcement learning control, and has methodological overlaps with other data-driven control, like artificial intelligence and robot control . An open-source platform, Reinforcement Learning for Grid Control (RLGC), has been developed and published for the purpose of developing, training and benchmarking RL algorithms for power system control . endobj Harnessing the full potential of artificial intelligence requires adaptive learning systems. environment includes the plant, the reference signal, and the calculation of the endobj [/PDF/ImageB/ImageC/ImageI/Text] actions directly from raw data, such as images. This element of reinforcement learning is a clear advantage over incumbent control systems because we can design a non linear reward curve that reflects the business requirements. How should Reinforcement learning be viewed from a control systems perspective?. In this final course, you will put together your knowledge from Courses 1, 2 and 3 to implement a complete RL solution to a problem. ؛������r�n�u ɒ�1 h в�4�J�{��엕 Ԣĉ��Y0���Y8��;q&�R��\�������_��)��R�:�({�L��H�Ϯ�ᄌz�g�������/�ۺY�����Km��[_4UY�1�I��Е�b��Wu�5u����|�����(i�l��|s�:�H��\8���i�w~ �秶��v�#R$�����X �H�j��x#gl�d������(㫖��S]��W�q��I��3��Rc'��Nd�35?s�o�W�8�'2B(c���]0i?�E�-+���/ҩ�N\&���͟�SE:��2�Zd�0خ\��Ut՚�.
