Chaos Firefly Algorithm With Self-Adaptation Mutation Mechanism for Solving Large-Scale Economic Dispatch With Valve-Point Effects and Multiple Fuel Options

This paper presents a new metaheuristic optimization algorithm, the firefly algorithm (FA), and an enhanced version of it, called chaos mutation FA (CMFA), for solving power economic dispatch problems while considering various power constraints, such as valve-point effects, ramp rate limits, prohibited operating zones, and multiple generator fuel options. The algorithm is enhanced by adding a new mutation strategy using self-adaptation parameter selection while replacing the parameters with fixed values. The proposed algorithm is also enhanced by a self-adaptation mechanism that avoids challenges associated with tuning the algorithm parameters directed against characteristics of the optimization problem to be solved. The effectiveness of the CMFA method to solve economic dispatch problems with high nonlinearities is demonstrated using five classic test power systems. The solutions obtained are compared with the results of the original algorithm and several methods of optimization proposed in the previous literature. The high performance of the CMFA algorithm is demonstrated by its ability to achieve search solution quality and reliability, which reflected in minimum total cost, convergence speed, and consistency

Modeling and Optimal Operation of Hydraulic, Wind and Photovoltaic Power Generation Systems

The transition to 100% renewable energy in the future is one of the most important ways of achieving "carbon peaking and carbon neutrality" and of reducing the adverse effects of climate change. In this process, the safe, stable and economical operation of renewable energy generation systems, represented by hydro-, wind and solar power, is particularly important, and has naturally become a key concern for researchers and engineers. Therefore, this book focuses on the fundamental and applied research on the modeling, control, monitoring and diagnosis of renewable energy generation systems, especially hydropower energy systems, and aims to provide some theoretical reference for researchers, power generation departments or government agencies

Can we break the addiction to fossil energy? : Proceedings of the 7th Biennial International Workshop Advances in Energy Studies

Sponsored by Obra Social "la Caixa", Norwegian Ministry of Petroleum and Energy, Universitat Autònoma de Barcelona and LIPHE4 Scientific Association, Generalitat de Catalunya.From 1998 onwards, every other two years, the Biennial International Workshop "Advances in Energy Studies" (BIWAES) gathers experts in what can be called energy analysis to present and discuss advances, innovations and visions in energy and energy-related environmental and socioeconomic issues and models. Renowned energy experts and ecologists, such as H.T. Odum, James Kay, Charles Hall, Tim Allen, Vaclav Smil, Robert Herendeen, Jan Szargut, Joseph Tainter and Robert Ulanowicz among others, have discussed at the BIWAES the importance of energy in our society and ecosystems and the ways to better analyze and model their complex relationships. Previous editions of BIWAES have focused on energy flows in ecology and economy; analysis of the supply side; the ecological consequences of energy sources exploitation; and the role of renewable energy sources and new energy carriers. The present Book of Proceedings refers to the seventh Edition, which took place in the month of October 2010 in Barcelona and addressed society's addiction to fossil energy
