Automatic Cost-Optimal Power Balance Control

The article presents application of evolutionary algorithm for cost-optimal dispatch of ancillary services in power transmission system of the Czech Republic. 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.
