Reactive power and voltage support is an essential service to ensure secure power system operations. Low voltages in the transmission grid pose threat to operational security of the grid. Certain control areas in the Southern regional grid in India experience severe low voltages during peak demand period. This paper provides an overview of the different methods being used by the grid operator to access...
In this paper, a Distribution STATic COMpensator (DSTATCOM) is proposed for compensation of reactive power and unbalance caused by various loads in distribution system. Distribution static compensator is based on the VSC principle. A D-STATCOM injects a current into the system to correct the voltage sag, swell and interruption An evaluation of a methods is made to derive reference currents for a DSTATCOM...
In this paper, the impact on nodal price determination of real and reactive power considering different reactive power price cost calculation methods for generator reactive power has been presented. The impact of FACTS controllers has also been considered taking their cost function into account. The comparison of fuel costs, reactive power cost, and cost of FACTS devices, and their impact on nodal...
In this paper, the nodal price for real and reactive power considering different reactive power price cost calculation methods for generator reactive power has been presented. The impact of FACTS controllers has also been considered taking their cost function into account.

Representational state transfer (REST) is an architectural style that has received significant attention from software engineers for implementing web-services due to its simplicity and scalability. By definition, web-services are distributed, headless (lacking UI) and loosely coupled. This presents the implementers and testers of web-services withchallenges, which are different from those in testing...
A hybrid wind park concept which contains both constant speed wind turbine and variable speed wind turbine is proposed in this paper, as it can provide similar power quality and similar low voltage ride through capability with relatively low investment. The objective is to optimize the configuration of a hybrid wind park which has low levelised production cost, high power quality, high reliability...
