DC Optimal Power Flow Formulation Using the Power Transmission Distribution Factors—A DIgSILENT Programming Language Application

Abstract

This research presents an application of different formulations to solve the DC optimal power flow problem. The classical DC optimization problem is reformulated using the power transmission distribution factors (PTDF). The main advantage of this formulation is the reduction of the decision variables in the optimization problem. In this chapter, the interior-point algorithm to solve the DC optimization problem is programmed using DIgSILENT Programming Language (DPL). In order to evaluate and compare the solution obtained by the algorithm, the simulations results are validated using MatPower. The proposed formulation has been implemented and validated with different test power systems. The results of the proposed algorithm demonstrate both the feasibility of applying the methodology to the DC optimal power flow problem and the potential applicability of the approach in medium-and large-scale power systems. The simulations performed in this chapter validate the formulation proposed in this study to solve the DCOPF problem. Finally, this application adds a new dimension to the DIgSILENT Power Factory by allowing the creation of new optimization algorithms to solve operation and planning problems.
