Abstract	This thesis presents a mathematical model for the Energy Management (EM) problem of a Microgrid (MG) by means of a Mixed Integer Linear Programming (MILP) approach. In the EM problem, the objective is to determine a generation and a controllable load demand schedule that minimizes, over a planning horizon, the operation cost subject to economical and technical constraints. It is proposed a detail modelling for Microturbines (MTs) and Fuel Cells (FCs), where the constraints associated with such factors as the ramps, minimum up and downtime, generation limits, and various peculiarities that have not been adequately considered in literature. Other important contribution of this thesis is the modelling of a specific energy storage system to the MG EM problem, the lithium-ion battery, comparing various approaches. The proposed model also considers a detailed representation of critical, reschedulable and curtailable loads, along with a new concept of diffuse loads, which could be important elements in the MG concept. To analyses the proposed modelling, a MG is used along with a MT, a FC, a battery, wind and photovoltaic generators, with the critical and controllable load demands, connected or island to the main grid. The study cases are divided into three big groups to verify the peculiarities of the MG EM, each Distributed Energy Resource (DER) and controllable load demand modelling. The results indicate that the model is adequate for the MG EM.
