This paper presents ways of estimating CO2 reductions of wind power using different methodologies. Estimates based on historical data have more pitfalls in methodology than estimates based on dispatch simulations. Taking into account exchange of electricity with neighboring regions is challenging for all methods. Results for CO2 emission reductions are shown from several countries. Wind power will...
Small autonomous power systems (SAPS) that include renewable energy sources are a promising option for isolated power generation at remote locations. The optimal sizing problem of SAPS is a challenging combinatorial optimization problem, and its solution may prove a very time-consuming process. This paper initially investigates the performance of two popular metaheuristic methods, namely, simulated...
Wind power is developing rapidly all around the world and at present total installed capacity is about 120,000 MW. Due to continuous improvements in turbine efficiency and increasing fuel prices, wind power is becoming economically competitive compared to conventional power generation. Combined economic/emission dispatch (CEED) involves the simultaneous optimization of two conflicting objectives namely...
Sustainable energy resources, particularly wind power, are rapidly becoming generation technologies of significance around the world. A multi-objective generation dispatch problem that considers environment and fuel cost under substantial penetration of wind energy is proposed in this paper. The nonlinear characteristics of thermal units and their operational constraints, such as generation limitations,...
With increasing concern of environmental protection, renewable energy sources especially wind power are widely applied as a mean to reach emission reduction. Although wind generation does not produce harmful emissions, its effect on the generation dispatch of conventional plants can actually cause an increase of emission especially during low and middle power demand period. A multi-objective generation...
In this work the impact of wind energy on the power flow is analyzed. After the development of a reduced sample network, possible network congestions are identified and the costs for the required redispatch of the generation are evaluated. To avoid or reduce the probability of congestions, different network upgrades can be installed. The efficiency of additional lines and power flow controlling devices...
