Power system planning and operation in present day are more in favour of economic factors and less in terms of technical aspects such as: system security, reliability and stability analysis. Case in point being: the generator scheduling or the pattern in load sharing among the various generators forms a major part in power system planning. Scheduling primarily based on economic criteria, essent...

This paper describes a methodology for transmission expansion planning (TEP) within a deregulated electricity market. Two objective functions including investment cost (IC) and congestion cost (CC) are considered. The proposed model forms a bi-level optimization problem in which upper level problem represents an independent system operator (ISO) making its decisions on investment while in the l...

In developing countries, power system planning faces nowadays enormous challenges and various problems as, for example, future load growth in the face of uncertainties associated with future load forecasting, the constraints imposed on investment, the type and availability of fuel for the generating units, the need for consolidating dispersed electric utilities in the isolated regions as a prer...

The problem of fault location has been studied deeply for transmission lines due its importance in the power system. Nowadays the problem of fault location on distribution systems is receiving special attention mainly because of the power quality regulations. This paper presents some of the most relevant methods for fault location in radial power systems. Additionally here is presented an hybri...

Smart grid integrates advanced sensing technologies, control methodologies, and communication technologies into current electricity grid at transmission and distribution levels in order to supply electricity in a smart, user friendly way. Smart grid encourages integration of renewable energy sources, distributed generation, and plug-in hybrid and electric vehicles in distributed power systems, ...

Currently, there is a need to plan and analyze the electric power transmission system in greater detail and over larger geographic areas. Existing models approach the problem from different perspectives. Each model addresses different aspects of and has different approximations to the optimal planning process. This paper presents a new modeling approach for inter-regional planning and investmen...

In the past, electrical transmission systems were continuously adding more facilities to their subsystems in order to satisfy the growing customer energy requirements. A utility industry traditionally has relied on a set of deterministic criteria to guide transmission planning. The traditional planning guidelines were based on planner's experience and intuition without a formal and consistent f...
