A method for optimal power system voltage and reactive power management which takes into account control of the interconnection reactive power flows is presented in this paper. The need for such control is evident as the voltage and reactive power scheduling in one power system can have serious impacts, including very negative, on the neighboring power systems. Moreover, according to the ENTSO-E network...
A sequential search strategy for the control variable subset selection, used for optimal power system voltage control and reactive power management, is presented in this paper. The objective of the presented selection method is to eliminate the redundant control variables which have small impact on the reactive power optimization (RPO) objective function and/or constraints. Selected control variable...
This paper presents a method of reactive power optimization based on partitioning of the power system daily load curve. The underlining problem that is being solved is the optimization of elements with defined maximum allowable daily operating times (MADOT). The daily load curve of the power system was partitioned into 24 stationary states which were used as a solution space for determining when to...
