| dc.description.abstract | This study investigates the modelling and simulation of an Energy Storage System (ESS) integrated with Automatic Generation Control (AGC) to improve fast frequency and voltage stability response in Uganda’s power grid, particularly within the Eastern transmission corridor. Increasing penetration of renewable energy sources has created significant challenges for maintaining grid stability, rendering conventional generation control methods insufficient during disturbances. A state-space mathematical modelling approach implemented in MATLAB is used to develop a dynamic representation of the power system incorporating generator dynamics, governor response, and Battery Energy Storage System (BESS) control mechanisms. The study evaluated three configurations: conventional AGC without storage, standalone ESS operation, and an integrated ESS–AGC control scheme. Performance evaluation was conducted under various disturbance scenarios including generator trips, load variations, renewable intermittency, and transmission faults. Simulation results demonstrated that conventional AGC alone produced poor dynamic performance, with frequency dropping to 47.871 Hz and bus voltage declining to 0.925 pu during a 30% generator trip scenario. Integration of ESS significantly improved system stability, with the proposed ESS–AGC configuration achieving a frequency nadir of 49.982 Hz, reducing Rate of Change of Frequency (RoCoF) by approximately 47.4%, and improving minimum bus voltage to 0.985 pu. Sensitivity analysis further revealed that a 10 MW BESS provides the optimal balance between technical performance and economic feasibility compared to 5 MW and 20 MW alternatives. The findings confirm that ESS-integrated AGC provides a technically viable solution for enhancing frequency and voltage stability in Uganda’s increasingly low-inertia grid environment and supports future renewable energy integration and regional power interconnection initiatives. | |
