This work addresses the integration challenges of Variable Renewable Energy (VRE) sources within the Kabertene wind farm and photovoltaic systems in Adrar, Algeria. Fluctuations in electricity consumption and the impact of weather conditions on power generation raise stability concerns for the southern PIAT grid. The PIAT grid includes distributed generation units, a wind farm, photovoltaic parks, dynamic RLC lines, and nonlinear D-ZIP loads. To ensure high power quality across the PIAT network, advanced control methods are developed, using IDA-PBC passivity theory and PID controllers for Kabertene's VRE components DFIGs and PVs. An Automatic Frequency Restoration Reserve (AFRR) is employed to stabilize frequency and voltages on the PIAT grid. A decentralized control approach is proposed, building on decentralized multivariable PID controllers, effectively managing voltage stability in generation units and dynamic loads. Simulation and analysis demonstrate the effectiveness of these techniques in enhancing grid stability, minimizing frequency deviations, and simplifying VRE integration. Practical implementation aspects are highlighted, emphasizing the transition to a cleaner, more sustainable energy system. [ABSTRACT FROM AUTHOR] |
