Hybrid Industrial Microgrid with Fractional Order Controller for Improved Frequency Stability

Increasing the integration of renewable energy sources into electrical power systems reduces overall inertia, leading to potential frequency instability. Effective control strategies are crucial to maintain frequency stability in hybrid industrial micro grids. This research proposes a fractional sliding mode control strategy for frequency stabilization in hybrid industrial micro grids. Explicit state-space model of a multisource hybrid industrial micro grid, includes load, energy storage systems, photovoltaic and wind farms, electric vehicles and batteries with state-of-charge control. This research investigates the effectiveness of the proposed controller based on fractional order to improve the frequency stability and micro grid performance. The proposed controller effectively damps frequency oscillations and maintains frequency stability under diverse scenarios. The controller demonstrates robustness, fast response, and reliability in managing frequency deviations.
