Automatic generation control is exhibited for multi-area hybrid solar-hydro-thermal system. Hybrid power system comprises of conventional thermal and solar thermal system in area 1. Conventional thermal system and hydro system with electric governor are positioned in area 2 and area 3 respectively. The conventional thermal systems are provided with single reheat turbine. Suitable generation rate constraint is provided in both hydro and thermal systems. The system dynamics with and without solar thermal are evaluated separately, considering conventional secondary controllers. Grey wolf optimizer (GWO) evolutionary computational technique is applied to simultaneously optimize the controller gains. Analyses reveal that system responses, with and without solar thermal, for PID controller are improved in comparison to other controllers. Investigation infers that the responses with reference to the hybrid system are enhanced with faster settling time and lesser deviation as compared to the system in absence of solar thermal. Wide variation in system conditions and parameters does not require resetting of GWO optimized PID controller gains. Robustness analysis authorizes the healthiness of GWO optimized PID controller gains found at nominal system condition.
