An environmentally conscious robust optimisation approach for planning power generating systems
This study proposes a robust optimisation capacity expansion planning model that yields a less sensitive solution due to variations in model parameters such as demand and fuel prices. By adjusting the penalty parameters, the model can accommodate the decision maker's risk aversion and yield a solution based upon it. The proposed model is then applied to Ontario Power Generation, the largest power ...

Equal to Removing 1 Million Cars from the Road Case Study
Powerphase commissioned a grid level analysis to assess how Turbophase technology could increase existing natural gas combined cycle gas turbine (GT) efficiencies in Florida, displacing baseload coal-fired generation and inefficient peaking plants to reduce electricity costs and pollution. Today’s electricity prices in Florida are higher than the national average, and while most of this ...

Prime Power Generation - Case Study
A national electricity grid must always be able to meet the needs of its users. This requires it to be: stable, maintaining the required electrical frequency (50 Hz in the UK); balanced, continuously matching supply to demand; and adequate, ensuring total generation capacity is never outstripped by demand. Grid supply is split into three tiers: base, intermediate, and peak load. Baseload is a ...

Efficiency of a standard gas-turbine power generation cycle running on different fuels
This paper presents a study of second-law efficiency in a standard Brayton combined cycle power generation, using several paraffinic fuels ranging from methane to heptane. The main objective of the study was to identify a trend with the number of carbon atoms in the compound. In this way, a qualitative criterion can be built to evaluate the properties of poor-quality gas turbine fuels containing ...

Exergy and industrial ecology: an application to an integrated energy system
Exergy analysis can help integrate separate technologies following the principles of industrial ecology. An application of exergy analysis to calculate depletion numbers, which relate exergy destruction and total exergy use, is demonstrated for a gas turbine cycle combined with a hydrogen generation unit. The design includes a Solid Oxide Fuel Cell (SOFC) with internal natural gas reforming and a ...

Understanding fuel switching under the EU ETS
Since the creation of the European Union Emission Trading Scheme (EU ETS), European power producers have monitored carbon emissions resulting from the composition of their production. Fuel switching is the main short–term abatement measure under the EU ETS. It consists in substituting combined cycle gas turbines (CCGTs) for hard–coal plants in off–peak power generation. Thereby coal plants run ...

Energy conservation and electricity sector liberalisation in the Netherlands and the UK: case studies on the development of cogeneration of heat and power, wind energy and demand-side management as energy conservation options
In this article, the development of combined heat and power, wind energy and demand-side management in the UK and the Netherlands are compared. It is examined to what extent these developments are determined by liberalisation of the electricity sector in both countries. The analysis suggests that unbundling of generation and distribution, rather than privatisation or introduction of competition ...

The Japanese fast-start finance contribution
Developed country governments have repeatedly committed to provide new and additional finance to help developing countries transition to low-carbon and climate-resilient growth. This assessment considers Japan’s efforts to provide “fast start finance” (FSF) between January 2010 and February 2012 in the context of the pledge by developed countries to mobilize USD 30 billion from ...

Efficiency and the not-to-be-ignored gas-fired plant
Carbon dioxide emissions dropped significantly in the US in 2009. The economy played an obvious role; not so obvious was the influence of power generation and its increasing efficiency. CO2 emissions have been trending down for the last decade by about 0.9%. But the 2009 drop was far more dramatic -- 7% -- the largest decline since the Energy Information Administration began keeping ...
