As global warming has become an issue that all human beings have to address, it is time to figure out how to reform our power system such that we can reduce the CO2 emission meanwhile stimulating the development of clean energy, such as wind energy. Because wind energy is not so dispatchable as fossil energy and it is always located in remote areas far away from high-power-demand areas, it is n...

A short-term electricity market coordinated by a system operator provides a foundation for a competitive electricity market. In this setting, transmission congestion contracts are equivalent to perfectly tradeable physical transmission rights. With such contracts to allocate transmission benefits, it would be possible to rely more on market forces, partly if not completely, to drive transmissio...

using new approaches to optimize the process of power transmission line routing can solve many complex problems which power transmission line routing decision-makers are faced. due to the expansion of involved parameters we can consider multi-objective evolutionary algorithms as appropriate method in this area. in this thesis with using multi-objective evolutionary algorithms nsga-ii and offere...

The problem of minimum-cost expansion of power transmission network is formulated as a genetic algorithm with the cost of new lines and security constraints and Kirchhoff’s Law at each bus bar included. A genetic algorithm (GA) is a search or optimization algorithm based on the mechanics of natural selection and genetics. An applied example is presented. The results from a set of tests carried ...

Ever-increasing energy demand has led to geographic expansion of transmission lines and their complexity. In addition, higher reliability is expected in the transmission systemsdue to their vital role in power systems. It is very difficult to realize this goal by conventional monitoring and control methods. Thus, phasor measurement units (PMUs) are used to measure system parameters. Although in...

This paper extends the transmission framework from Joskow and Tirole (2005) to show how intermittent renewable capacity increases interact with transmission constraints both theoretically and empirically. The main prediction of the model is that transmission congestion leads to mitigated benefits from renewables due to lack of electricity to be traded to high priced market settlement points. We...

This paper aims to quantify the long-term economic benefits that arise from an increasing integration of the pan-European electricity system by means of comparing model-based decarbonization scenarios developed with the model LIMES-EU+. It explicitly accounts for the interplay between transmission infrastructure and renewable generation capacity expansion. We confirm earlier findings that, on a...

A method is proposed for analysis of arbitrarily loaded lossy and dispersive nonuniform single or coupled transmission lines. In this method, all the per-unit-length parameters or matrices of the single or coupled lines and also the voltages and currents along the length of them are expanded in Taylor’s series. The solutions of voltages and currents are obtained after finding unknown coefficien...
