Study on economic dispatch of thermal generation considering the presence of wind and solar generation

Abstract

This Scientific Initiation work aims to promote a study on thermal generation dispatch, considering the presence of wind and solar energy sources, and consequently to present a mathematical model that contemplates the economic dispatch of both types of power generation. The mathematical model will aim to minimize an economic power generation function considering thermal, wind and solar generation. In this way, it is intended to optimize thermal generation with the presence of wind and solar generation, to meet a specific load demand. In the mathematical model, the technical and operational restrictions of networks and thermal, wind and solar generation systems will be considered. The models of wind and solar generation should consider the uncertainties of wind speed and the dependence on solar radiation, respectively. For the development of the work, studies on thermal, solar and wind generation systems will be made, considering mathematical models of these systems, available in the literature. The present work is only about studies and presentation of mathematical models, and does not consider the study of solution techniques to solve the problem or even implementations. However, this work will be a starting point for the study and use of advanced solution techniques that considers the resolution of problems with uncertainties (wind and solar generation), as well as the implementation of these methods. In addition, this model may, in a future work, consider the issue of environmental dispatch, assessing the CO2 emission with reduced energy generation from thermal plants. (AU)
