Özet
Nonlinear structure, vague loading characteristics and parameter uncertainties of the interconnected power system (IPS) have recently given birth to various controllers that better deal with automatic generation control (AGC). AGC plays a key role in ensuring the balance of generation and load demand in IPSs. If this balance is lost, then the system faces large frequency deviations. Thus, this work proposes a new fuzzy 1 + proportional + derivative-proportional + integral (F1PD-PI) controller to escalate AGC performance of different IPSs integrated with renewable energy sources (RES) including wind, solar and fuel cells. Inspiration for the proposed controller is unique and comes from combining the merits of fuzzy, 1PD and PI controllers. Salp swarm algorithm (SSA) is utilized to optimize the proposed controller's gains as well as fuzzy membership functions. The effectiveness and contribution of the advocated approach are demonstrated on a two-area reheat thermal system and a two-area multi-source hydro-thermal system by realizing an extensive comparison study with the state-of-the-art variants. The results substantiate that SSA optimized F1PD-PI controller has better performance than its competing peers in terms of minimum settling time, peak undershoot, peak overshoot and error-integrating performance criterion of the system responses. Nonlinearities from governor dead band and generation rate constraint are also studied, which verifies the performance of the control strategy in tackling nonlinearities. Additionally, the robustness of the controller is affirmed against parameter uncertainties and load disturbances. Finally, the stability of our proposal is checked using eigenanalysis.
