“…With reference to Fig. 1, the two PSTs can be controlled in a coordinated way to reduce the fraction of power flow passing through as a result of the transaction from G to D. More PSTs are likely to be installed for increased control of transit flows, as testified by the situation in Belgium, where three PSTs are going to be put in operation on the Northern border of the country [14], [15].…”

Abstract-More and more transmission system operators, noticeably in Europe, equip their systems with phase shifting transformers to counteract transit flows that take place in a large meshed interconnection. This paper proposes algorithms for the coordinated control of several phase shifters by one operator with the objective of reducing the unscheduled flow through its system. Minimum reduction of unscheduled flow and minimum deviation with respect to present operating point are sought in order to minimize the trouble caused, while ensuring secure operation. Attention is paid to combining pre-and post-contingency controls. The resulting algorithms, simple and compatible with real-time applications, are illustrated on a realistic test system. Index Terms-Corrective control, correctively secure operation, optimal power flow, phase shifting transformer, preventive control, transit flow, unscheduled flow.

“…The PAR (Phase Angle Regulator) phase shifters are used to control the active power flow of transmission lines by changing the phase difference between buses [11]. The influence of this device on the line power flow can be modeled by the phase shift, , and can be expressed by the following equation:…”

The DC load flow is a rapid and approximate solution method for the determination of lines active power flows in power systems. In this paper, the HVDC (High Voltage Direct Current) links and FACTS (Flexible AC Transmission Systems) devices have been modeled in the DC load flow analysis. In order to evaluate the performance of the proposed method, the proposed DC load flow results have been compared with the AC or AC-DC load flow results of DIgSILENT software. It is shown that the proposed DC load flow is accurate enough for power system studies.

Abstract-In this paper, a control scheme is demonstrated that regulates multiple Phase Shifting Transformers (PSTs) to equally load the interconnectors of a border. A crucial step in the development of the control scheme is the derivation of Phase Shifter Distribution Factors (PSDFs), which indicate the influence of a PST on the active power flow on a certain line. Based on these PSDFs, the Linear Least Squares (LLS) method is used to calculate the optimal PST settings. The degree to which an even repartition can be obtained, depends on the number of PSTs in relation to the number of interconnectors. As a casestudy, simulations are performed involving the Dutch and Belgian interconnectors.
