This paper proposes an approach to optimally allocate multiple types of flexible AC transmission system (FACTS) devices in market-based power systems with wind generation. The main objective is to maximize profit by minimizing device investment cost, and the system's operating cost considering both normal conditions and possible contingencies. The proposed method accurately evaluates the long-t...

Flexible AC transmission system; Static synchronous compensator (STATCOM); Optimal reactive power dispatch (ORPD); Chemical reaction optimization (CRO); Transmission loss Abstract Optimal reactive power dispatch (ORPD) problem has a significant influence on optimal operation of power systems. However, getting optimal solution of ORPD problem is a strenuous task for the researchers. The inclusio...

To meet with the ever-enhancing load demands, new transmission lines should be bolted-on in the existing power system but the economic and environmental concerns are major constraints to this addition. Hence utilities have to rely on the existent power system infrastructure with some modifications. To enhance controllability and boost power transfer potential of the existing power system the us...

The Static Synchronous Series Compensator (SSSC) is one of the powerful Flexible AC Transmission System (FACTS) controller recognized for power flow, power oscillation damping and improving transient stability. This paper proposes controller that is a combination of Fuzzy Logic Power Oscillations Damping (FLPOD) controller with Proportional and Integral Power Flow (PIPF) controller for SSSC to ...

<span lang="EN-US">Transmission systems are prone to contingency conditions that would either occur using a generator outage or line outage. Placing and sizing the flexible ac transmission (FACTS) devices appropriately can reduce effects of condition. This paper optimally locates FACTS in system under N-1 The genetic algorithm (GA) technique is used locate different, multiple (thyristor-c...

In the previous studies the effect of Static Var Compensator (SVC) and Power System Stabilizers (PSS) has not been considered specially for various faults in a three phase system. For improvement in inductive and capacitive power flows Shunt Flexible AC Transmission System (FACTS) devices can be used and when they are placed in the center of transmission line of a electrical power transmission ...

This paper proposes and validates models to accurately represent STATic Synchronous Shunt COMpensators (STATCOM) in voltage and angle stability studies of powers systems. The proposed STATCOM stability models are justified based on the basic operational characteristics of this Flexible AC Transmission System (FACTS) controller for both phase and PWM control strategies. These models are first va...

This paper presents an Interior Pont Method (IPM) and Evolutionary Particle Swarm Optimization (EPSO) based hybrid method to solve optimal power flow in power system incorporating Flexible AC Transmission Systems (FACTS) such as Static Synchronous Series Compensator(SSSC) for security enhancement in the power systems. A fuzzy logic composite criteria based severity index is also used as an obje...

This paper presents voltage stability in an electrical network when connected by wind generators. Due to several advantages wind energy is the growing renewable energy. Nowadays, wind energy is penetrating into the conventional power network. Due to random variations in wind speed, the output power and terminal voltage fluctuates continuously. The influence of wind generators on the power quali...
