This master dissertation presents a power management tool of a power system operating in a Smart Grid that contains Electric Vehicles inserted as loads and Wind Power Generation. The optimization technique used was Simulated Annealing, in order to minimize the total energy cost of the network being studied. Three charging strategies were adopted: Peak Charging, Off-peak Charging and Smart Charging besides Demand Side Management techniques. In addition to the charging process will also be studied the Discharging of the battery electric vehicles, preferably at the peak of the load curve, as well as the possibility of supplying grid power through the wind farm to supply both loads in the topology of the system as for the loads of electric vehicles inserted through the creation of a charging/ discharging station. The system used is the IEEE - 39 bus New England power system. The results proved the effectiveness of the proposed method and the importance of considering besides distribution as well as generation and transmission in studies of planning, expansion, and operation of Smart Grids that contain Electric Vehicles and Wind Power Generation.

The evolution of turning traditional grid into smart grid has contributed the enhancement of penetration of distributed generation in electric systems. Furthermore, the greater integration of Information and Communication Technology (ICT) and Power Electric Systems (PES) has provided the commitment among costumers and demand side management (DSM), which has become increasingly more interested in the last years. Nevertheless, being such a debated topic since 1980, it only has been more defunded throughout the smart grid. Hence this point of view, the costumer must understand some strategies of demand side management in order to take some advantage of this program. Therefore, this master’s dissertation aims developing a Home Energy Management System (HEM), in order to assist the costumer in making up his decision of the load shifting, providing scheduling proposals for home energy consumption, in Demand Response (DR) in order to reduce consumer spending on the purchase of energy provided by the concessionaire and optimize the use of photovoltaic generation.
