For decades, high voltage alternating current (HVAC) has been the more conventional method of power delivery. With recent advances in power electronics, high voltage direct current (HVDC) is an established technology in long-distance bulk power transmission. It is re-emerging to be the better option due to improved system operation and better support in the development of onshore and offshore transmission...
Power System stability is an essential study in the planning and operation of an efficient, economic, reliable and secure electric power system because it encompasses all the facet of power systems operations, from planning, to conceptual design stages of the project as well as during the systems operating life span. This paper presents different scenario of power system stability studies on a modified...
This paper presents a critical scenario of voltage stability study on a multi-machine system when subjected to different loading patterns. High Voltage Direct Current (HVDC) links control and the effects of its compensating devices' effects on voltage stability are also investigated. A static approach with the use of P-V (Power-Voltage) and Q-V (Reactive power-Voltage) curve was used in this study...
Increase in the market share of wind energy in total electricity generation and its impact to power grid has imposed new challenges to the stability of each wind turbine generator (WTG) unit. In the case of power undersupply, the problem on voltage stability and voltage collapse will eventually occur. In this paper, the impact of reactive power control in improving the performance of squirrel cage...
