This research proposes an additional controller for load frequency control at a micro hydro power plant using PID-SMES. The PID-SMES parameters are optimized using smart methods, Imperialist Competitive Algorithms (ICA), which can find the optimal value of PID-SMES. From the analysis results, obtained on the P controller, overshoot of -0.0002176, with PI Controller -0.0002167, with PD Controller -0.0002128, with PID controller -0.0002118, with SMES controller -0.0001951, and with PID-SMES -4.11e-05. ICA optimization results obtained fitness function value of 1.79846040002633e-08, with 40 iterations. The minimum value of the system performance function at each iteration is plotted on the convergence graph shown. In the Figure it can be seen that the ICA algorithm can quickly converge on the 14th iteration or find the most optimal value at the 7th iteration. The PID-SMES controller proposed in this study has a significant influence in the damping of the oscillations. Therefore, it is proposed to be applied to micro-hydro.
