Power Flow Analysis in Power System Planning. Case Study

The power flow solution is one of the more significant issues in power systems. In this article we will describe a comparison between using of two tools for Power flow and Voltage analysis: program 1 and program 2. Our study case includes the results in the calculation of Power Flow and Voltage analysis in the nodes of High Voltage network. The power network has 13 nodes, 11 generators (Five generating units), 27 power transformers, from which 16 transformers are used as a loads, and the network operating at 10.5 kV up to 220 kV. The loads are depending on the voltage. The total losses in this network are calculated, and the level of voltages in all of nodes, calculated with both programs. Also, we do operate the power network in the best case in terms of Reduce losses in the network, taking into account the voltages regulation. The study is focused on the voltage control in the power network. Solutions for dynamic control of the voltage in power system are proposed in the paper.
