Control effectiveness of FACTS devices in power systems

2016 American Control Conference (ACC), 2016
This paper analyzes the fault tolerant control of a power grid with FACTS devices. Control effectiveness measures the small signal combined controllability and observability of a power system with tolerance to prescribed contingencies. This paper also focuses on the roles of FACTS devices in affecting the grids redundancy architecture.

Model Checking Control Communication of a FACTS Device

2006 International Conference on Parallel Processing Workshops (ICPPW'06), 2006
This paper concerns the design and verification of a realtime communication protocol for sensor data collection and processing between an embedded computer and a DSP. In such systems, a certain amount of data loss without recovery may be tolerated. The key issue is to define and verify the correctness in the presence of these lost data frames under ...

FACTS devices for stability enhancements

2015 International Conference on Green Computing and Internet of Things (ICGCIoT), 2015
FACTS devices are used to control the voltage profile and stability of power system by improving transient and dynamic stability. Particle swarm optimization (PSO) technique is used in place of Genetic Algorithm (GA) for minimization of losses and simulation process.

Protection of Reactors and FACTS Devices

2019
Reactors and static var compensator (SVCs) protection strategies are presented in Chapter 9. Reactors are used in AC networks to limit either overvoltage for series connections or short-circuit current if connections are parallel. SVC systems come in a large number of arrangements, and they are custom-designed for specific applications such as reactive

EMTDC Simulation Model for FACTS Device

2005/2006 PES TD, 2006
This paper describes the impact of the FACTS application on the power network using EMTDC simulation package. KEPCO (Korea Electric Power Corporation) has begun the operation of the plusmn80 MVA UPFC (unified power flow controller) from the year 2003 on the 154 kV transmission system. The UPFC consists of two voltage source inverters (VSI), STATCOM and

Voltage flicker mitigation by FACTS devices

2014 International Conference on Circuits, Power and Computing Technologies [ICCPCT-2014], 2014
This paper deals with the Voltage flicker in power systems. Voltage flicker is one of the disturbances in power systems. This voltage flicker occurs due to non linear loads. A three phase four wire inverter system is consider to compensate the voltage flicker.

Use of Max-Flow on FACTS devices

2007 39th North American Power Symposium, 2007
FACTS devices can be used to mitigate cascading failures in a power grid by controlling the power flow in individual lines. Placement and control are significant issues. We present a procedure for determining whether a scenario can be mitigated using the concept of maximum flow.
