As the demand of electricity from an already congested network increases, ensuring voltage stability across the network becomes challenging. One approach in ensuring system stability is to attain system redundancy but their economic and ecological limitations to this. A more cost effective means would involve the use of existing network component and incorporate less expensive scheme and policies to maintain reliable system operation. […]

Modern power systems are operating under much stressed conditions and this is making the system to operate closer to their operating limits. Since a couple of decades ago voltage stability assessment has received an increasing attention due to the complexity of power system. With the increase in power demand and limited power sources has caused the system to operate at its maximum capacity. Therefore, a study that is able to determine […]

When designing power transmission systems, electric utility companies are expected to follow a set of standard specifications that are briefly described in this research. The idea to be kept in mind is that during the planning and construction phases of transmission lines, natural elements, such as trees for example, there will be less of a chance of fault occurrences and therefore more power system reliability. Faults in transmission […]
Efficient electric power transmission is a major concern in Nigeria. Electric power transmission is the link between power generation and power distribution network. The performance evaluation of the 132/33KV Sub-transmission lines is a research work carried out to ascertain the status of the networks for better performance. This paper addresses the defects identified in the power network, including transmission substations, distributi […]
Management of reactive power and voltage control constitute part of the major challenge in power system industry. Adequate reactive power control solves power quality problems like voltage profile maintenance at all power transmission levels, transmission efficiency and system stability. Power demand increases steadily while the expansion of power generation and transmission has been severely limited due to the inadequate resources and […]

ABSTRACT In the expanding transmission network, Congestion management and voltage stability are significant issues to be handled. Congestion management can be improved by increasing the power transfer capability or by reducing the system losses. With proper VAR support, the issue of voltage instability can be vanquished. Adaption of Flexible AC Transmission System (FACTS) devices is a techno-commercial manner to overcome the above iss […]
