     this paper presents the automatic generation control (agc) of an interconnected two-area multiple-unit hydro–hydro system. as an interconnected power system is subjected to load disturbances with changing frequency in the vicinity of the inter-area oscillation mode, system frequency may be severely disturbed and oscillating. to compensate for such load disturbances and stabilize the area frequency oscillations, the dynamic power flow control of static synchronous series compensator (sssc) or thyristor controlled phase shifters (tcps) in coordination with superconducting magnetic energy storage (smes) are proposed. smes–smes coordination is also studied for the same. the effectiveness of proposed frequency controllers are guaranteed by analyzing the transient performance of the system with varying load patterns, different system parameters and in the event of temporary/permanent tie-line outage. gains of the integral controllers and parameters of sssc, tcps and smes are optimized with an improved version of particle swarm optimization, called as craziness-based particle swarm optimization (crpso) developed by the authors. the performance of crpso is compared to that of real coded genetic algorithm (rga) to establish its optimization superiority.
