Emission of greenhouse gases and their effects on climate change have become a matter of serious concern all over the world. In addition, electricity demand is expected to increase in the upcoming years. This growth comprises the construction of new power plants, resulting in additional costs on the price of electricity. Due to what is been exposed before, a new way to manage and generate electricity is needed. Recent researches have provided the tools for modernizing the traditional electricity grid into a smart one, which main objective is to coordinate an ever-growing number of intelligent de- vices, each with their own objectives and value perspectives, into a resilient, secure, and ef- ficient system. Here is were the flexibility concept plays an important role in the upcoming energy transition, understanding flexibility as the ability to change certain previously defined parameters in order to fit new requirements. This Master Thesis focuses on the prosumer flexi- bility concept, quantifying his flexibility potential. This flexibility is used to minimize the total expected costs of each prosumer individually, thus reducing their electricity bills. The method- ology developed consists in a Home Energy Management System (HEMS) that will manage automatically that flexibility in order to benefit the end user by minimizing its electrical bill, where the comfort is also taken into account. The results show that it is possible to reduce the electricity invoice by managing optimally the flexibility from loads, batteries, photovoltaic generation and electric vehicles charging points. |
