Optimal Frequency stability Control Strategy for a Grid-Connected Wind/PV/FC/BESS Coordinated with Hydroelectric Power Plant Storage Energy System Using Variable Structure Control

Because of the growing nonlinear and complexity nature microgrid systems for example battery energy storage systems, wind-turbine fuel cell, photovoltaic, micro hydro power plants (BESSs/FC/WT/PV/ Micro Hydro), load-frequency management has been a difficulty. The development controller based on Proportional–Integral–Derivative (PID) an autonomous (MG) with hydro, wind, PV RES is shown in this article. suggested LFC goal to retain frequency plant under variable load situations by controlling sharing output constant generator between dummy loads consumer. Using adaptive fuzzy logic govern nearly generating unit`s whole operation, control technique optimally chooses PID settings each value. logic-based regulates plant's despite fluctuating user manages distribution separating network into separate departures connected priority order. uses centralised approach centred combination smart Battery Energy Storage System manage MG (BESS). It providing active balancing variety events that such face real-world settings, as surplus generation shortage. In Simulink/MATLAB, structure simulated. simulation results clearly demonstrate proposed controller's ability dump extra when customer varies while maintaining consistent supply frequency.
