Automatic controller for cost-optimal power balance control

The paper presents application of evolutionary algorithm for cost-optimal dispatch of ancillary services in power Czech transmission system. The problem is formulated as a nonlinear optimization problem taking into account both continuous and discrete control variables. The optimal setting of control variables such as schedule for activation of regulation reserves, which minimizes the regulation energy costs while maintaining required control performance are determined via evolution algorithm. The proposed control scheme is tested on historical data from the transmission system operator.
