“…In a transmission system, one of the lines may become overloaded while a line along an alternative path may be lightly loaded. Rerouting the flow from overloaded lines to more lightly loaded lines can improve the utilization of the existing transmission system, thus delaying the investment in transmission system infrastructure [13].…”

“…Reference [12] proposed the use of an active smart wire, which is a DSR module with an AC capacitor, two AC switches and a communications package, for controlling power flows on a strained grid. In [13] the authors studied the impact of smart wires, which are standard transmission lines that are augmented with DSRs, in reduction of transmission investment required to implement policies like the Renewable Portfolio Standards (RPS). References [14] and [15] introduced the concept of Distributed FACTS (D-FACTS) as an alternative approach to realizing cost-effective power flow control.…”

An important issue in today's power system is the need to analyze and determine the adequacy of transmission capacity. There is a need for approaches to increase transmission system capacity without construction of new transmission facilities, all while assuring secure operation of the grid. Distributed Series Reactors (DSRs) are a new smart grid technology that can be applied to control flows in transmission or distribution systems. DSRs can be used to balance phase flows in a single line as well as to control the distribution of flow in a meshed system. This paper investigates DSRs to control power flow to alleviate overloads due to increased power transfer. The IEEE 39 bus standard model is modified to a 3-phase unbalanced transmission model with 345 kV lines that accounts for tower geometry. Using the symmetrical components transformation, a balanced, 3-phase model is then derived from the unbalanced, 3-phase model. DSR designs based on the unbalanced, 3-phase model and the balanced, 3-phase model are compared and used to demonstrate the effectiveness of DSR control in handling load growth. Only unbalanced impedances are addressed i.e., non-transposed lines, but the effects of impedance unbalance are shown to be significant on the resulting DSR design.

Summary The transmission system expansion planning process requires lots of calculations looking many years into the future, and the results are based on assumed load growth. If the load growth assumed in the planning process is not correct and unexpected load growth occurs for some load points, the transmission system could face serious congestion and even overloading problems. In this paper, transmission line impedance adjustment techniques using distributed series reactance (DSR) is considered. The DSRs can be used to control power flow and alleviate overloading problems. A new term, DSR congestion relief factor, is introduced. The DSR congestion relief factor measures the increase of transmission line capacity with the application of DSRs. Parametric studies run on the IEEE 39‐bus system are presented. These studies investigate the economic benefits of DSRs and the use of DSRs for single contingencies and compare DSRs with existing technologies for expanding the transmission system.

“…Due to the geographical dispersion, the interstate tie-lines are often very long. So, they require large capital investment for installation and upgrade [2]- [5]. The increasing operational dynamics due to liberalized electricity markets, and growing load have pushed the existing grid to unusual levels of stress.…”

This paper presents the distributed series reactor (DSR) as a low cost D-FACTS technology that can be easily clamped on working transmission lines at higher operational reliability and without the need of any communications or centralized control. Smart wires are standard transmission lines that are augmented with a large number of DSRs. The paper addresses the potential of the emerging smart wire technology in improving the utilization and reliability of the existing transmission, sub transmission, and distribution networks. It proposes a smart-wire based strategy for planning power systems with increasing penetration level of wind generation. Moreover, the paper evaluates the potential of the smart-wire technology to reduce the required investment for congestion-free transmission system upgrading plan. The proposed approach is applied to the IEEE 39-bus and IEEE 57-bus test systems. Comparative analysis of results is provided for the classic and smart planning methods.
