Improvement of Power Quality in Grid Connected Hybrid Wind-PV-Battery based Microgrid with LSTM

Grid connected distribution generators mainly supplied by hybrid renewable energy sources are popular nowadays to reduce global warming as well as to meet electrical load demand which increased day by day worldwide. A storage device is integrated to the system to make continuous power supply to loads during off grid mode by making an efficient energy management system. In order to make the proposed system more stable, a novel energy management system is developed. The presented control can able to compensate reactive power, stabilize voltage at load bus, compensation of unbalanced voltages as well as harmonics. LSTM controllers are interfaced in the proposed control method to achieve fast responses during rapid changes. Various results with realistic nature are adopted by developing Hardware-in the-Loop through OPAL-RT modules. Extensive results are examined under various case studies to enhance the significant of proposed method.
