TL;DR: In this paper, the technologies required to yield an energy conversion efficiency greater than the Advanced Turbine Systems Program target value of 60% are discussed and the goal of achieving 60% efficiency is achievable through an improvement in operating process parameters for both the combustion turbine and steam turbine, raising the rotor inlet temperature to 2,600 F (1,427 C).
Abstract: In cooperation with the US Department of Energy`s Morgantown Energy Technology Center, Westinghouse is working on Phase 2 of an 8-year Advanced Turbine Systems Program to develop the technologies required to provide a significant increase in natural gas-fired combined cycle power generation plant efficiency. In this paper, the technologies required to yield an energy conversion efficiency greater than the Advanced Turbine Systems Program target value of 60% are discussed. The goal of 60% efficiency is achievable through an improvement in operating process parameters for both the combustion turbine and steam turbine, raising the rotor inlet temperature to 2,600 F (1,427 C), incorporation of advanced cooling techniques in the combustion turbine expander, and utilization of other cycle enhancements obtainable through greater integration between the combustion turbine and steam turbine.

TL;DR: In this article, the authors proposed a shift from ac to dc for long distance transmission of bulk power in HVDC-based power transmission systems, which has become the dominating technology for long-distance transmission of power.
Abstract: During the last 20 years, HVDC has become the dominating technology for long distance transmission of bulk power. In the 1960s and 1970s, 800 kV HVAC was introduced in several countries. But that technology has come to a halt. In contrast, HVDC technology has developed rapidly and so has confidence in it, resulting in a shift from ac to dc for bulk power transmission systems.
TL;DR: In this article, the National Grid Company plc (NGC) has identified the need for reactive power plant that can be relocated at short notice, and GEC Alsthom's T&D division has been commissioned to design and install three relocatable static var compensators at NGC's Iron Acton substation near Bristol.
Abstract: In competitive electricity markets, the operators of electricity transmission networks may no longer have direct control over the siting of power plant nor of the timing of plant retirement. Combined with variability in load patterns, these changes lead to new requirements for reactive power control and power system planning. In England and Wales, the National Grid Company plc (NGC) has identified the need for reactive power plant that can be relocated at short notice, and GEC Alsthom's T&D division has been commissioned to design and install three relocatable static var compensators at NGC's Iron Acton substation near Bristol.
