Currently, power systems are involuntarily controlled without high speed control and are frequently initiated, therefore resulting in a slow process when compared with static electronic devices. Among various power interruptions in power supply systems, voltage dips play a central role in causing disruption. The dynamic voltage restorer (DVR) is a process based on voltage control that compensat...

Abstract This paper uses a Grasshopper Optimization Algorithm (GOA) optimized PDF plus (1 + PI) controller for Automatic generation control (AGC) of power system with Flexible AC Transmission (FACTS) devices. Three differently rated reheat turbine operated thermal units appropriate rate constraint (GRC) are considered along different FACTS A new multistage design structure is introduced in the ...

This paper presents a new system configuration for a large-scale Photovoltaic (PV) power system with multi-line transmission/distribution networks. A PV power plant is reconfigured in a way that two adjacent power system networks/ feeders can be interconnected. The inverter modules in a PV power plant are configured such that the system is represented as a back to back inverter connected multi-...

Problem statement: FACTS devices play a major role in the efficient operation of the complex power system. FACTS devices such as STATCOM, SSSC and IPFC are in increasing usage. With energy storage systems they have a good control over the real as well as reactive power compensation and transient stability improvement. The design of controller for the SSSC with SMES system is analyzed in this st...

This paper presents a new Unified PowerQuality Conditioning System (MCUPQC),capable of simultaneous compensation for voltage and current in multi-bus/multi-feeder systems. By using one shunt Voltage-Source Converter(VSC) and two or more series VSCs the configuration is made. The system can be applied to adjacent feeders to compensate for supplyvoltage and load current imperfections on the main ...

This paper presents exhaustive review of various methods/techniques for incorporation of differential algebraic equations (DAE) model of FACTS controllers in multi-machine power system environments for enhancement of different operating parameters viewpoint such as damping, voltage stability, voltage security, loadability, active power and energy losses, power transfer capability, cost of gener...

For system operators, Congestion management is a difficult task as the market’s security and reliability are protected by this methodology. As magnitude of an electric transmission extremely dynamic, limits must be estimated much beforehand, in order to manage congestion issues at right time. Flexible AC systems (FACTS) used control voltage fluctuation adjusting system's real reactive power. A ...
