Ray Tracing Technique For The Optimal Design Of An Air Heater Concentrating Collector, Fernando Guerreiro
Ray Tracing Technique For The Optimal Design Of An Air Heater Concentrating Collector, Fernando Guerreiro
Student Journal of Energy Research
There is a wide range of micro and macro renewable and sustainable energy methods available for reducing the inefficient use of fossil fuels, minimising carbon emissions and maximising energy use in a clean and environment-friendly process. Solar energy plays an important role due to its abundance and ubiquity. Solar air heaters convert solar energy into hot air to be used for heating and drying of various products. The objective of this paper is to define and optimise the geometry of an inverted absorber compound parabolic concentrating (IACPC) collector for air heating. This optimisation was developed based on an optical analysis …
Short Term Demand Forecasting For The Integrated Electricity Market, Katie Kavanagh
Short Term Demand Forecasting For The Integrated Electricity Market, Katie Kavanagh
Student Journal of Energy Research
This paper presents a means for the short term load forecasting (STLF) of electricity. The forthcoming Integrated-Single Electricity Market (I-SEM) diverges from the current market structure (the Single Electricity Market or SEM), with significant impacts on Irish supply companies, creating a need for these companies to be able to accurately forecast their customers’ load in the Day Ahead. Using a Double Seasonal Exponential Smoothing variation of the Holt-Winters method that factors in an error correction, data from the Irish market was trained and used to forecast a supply company’s demand resulting in an average daily MAPE (Mean Absolute Percentage Error) …
