A current-based model of the static synchronous series compensator (SSSC) for Newton–Raphson power flow

A current-based model of an IPFC for Newton–Raphson power flow

“…The first step when studying new possibilities in the system should be the power flow calculation, and in order to be able to carry out this type of analysis the power flow models for FACTS devices have to be available. For typical FACTS devices, i.e., SSSC [1,2], STATCOM [3,4], IPFC [3,5,6], UPFC [3,[7][8][9][10], and GUPFC [3,5], such models have already been constructed for applications in Newton power flow. The existing power flow models for FACTS devices are mostly incorporated into node equations describing the power system via the injected voltage and the devices' impedance.…”

“…By applying the so-called current-based model of an SSSC considerably better results have been achieved (i.e., faster convergence and a wider area of convergence) than those achieved by applying the VSC model. The details of SSSC modeling in Newton power by applying a current-based flow approach are described in [2].…”

The Imperialist Competitive Algorithm for Optimal Multi-Objective Location and Sizing of DSTATCOM in Distribution Systems Considering Loads Uncertainty

“…Researches have shown that installation of FACTS based equipment in the power distribution system could lead to achieve many benefits such as voltage profile improvement, reduction in lines losses, security enhancement for critical loads, reduction in the on-peak operation cost and improvement in the power quality and reliability of supply (Patel et al 2016). This equipment includes solid state transfer switch (SSTS), dynamic voltage restorer (DVR), distribution static compensator (DSTATCOM) and unified power quality conditioner (UPQC) (Chandrasekaran and Ramachandaramurthy 2016;Vinkovic and Mihalic 2008). In this paper, DSTATCOM as a shunt connected voltage sourced converter (VSC) is employed to enhance of objectives.…”

Pseudo-loadflow formulation as a starting process for the Newton Raphson algorithm

“…A brief review of many of the significant contributions in this area is included by Milano [7]. Although loadflow solution is now a routine task in power system analysis, the introduction of new system models and new solution methods continues to be of interest [13][14][15][16][17].…”

“…In such cases the pseudo-loadflow can help the analyst to find the likely causes of infeasibility of the AC loadflow, such as errors in the input data. It is also hoped that the proposed methods may be applicable in cases where the introduction of FACTS devices increases the nonlinearity of the loadflow problem [13][14][15].…”
