Multi-Objective Optimal Operation for Transmission Systems Considering Voltage Stability

Abstract

Abstract Due to the liberalization of electric power market, many power producers are entering into the power market. Most of electric power company have been introduced renewable energies that might increase the power system uncertainty. Therefore, it is expected that rise might the likelihood of voltage instability and voltage collapse. In addition, fluctuations in supply and demand are increased by the introduction of a renewable energies. However, by using the Energy storage systems (ESS), the power fluctuations can be reduced. On account of this, we suggest the optimal operation method of the generator and the ESS by considering the voltage stability in this paper. The effectiveness of the proposed method is verified by simulation results in the Matlab/simulink.
