  • Data-Driven Load Frequency Control for Stochastic Power

    Nov 14, 2018 · This letter proposes a data-driven, model-free method for load frequency control (LFC) against renewable energy uncertainties based on deep reinforcement learning (DRL) in continuous action domain. The proposed method can nonlinearly derive control strategies to minimize frequency deviation with faster response speed and stronger adaptability for unmolded system dynamics. It consists of

  • Contiguous Pile Wall as a Deep Excavation Supporting System

    For deep cuts, lateral restraint can be provided by horizontal wales with either raker braces or by tieback anchors. For shallow excavations, a cantilevered wall is generally sufficient to resist earth pressures. Narrower excavations can be braced with cross struts. Diaphragm walling is a technique of constructing a continuous underground wall from

  • Heat Treatment and Ventilation Optimization in a Deep Mine

    In order to address the issue of high temperatures and thermal damages in deep mines, the factors causing downhole heat damage at high temperatures were analyzed, the mine ventilation system was optimized and rebuilt, and a cooling system was established. The proposed cooling system uses mine water as the cooling source, and its features are based on the analysis of traditional cooling systems.
