1. Increasing Energy Efficiency in Electric Trains Operation : Driver Advisory Systems and Energy Storage
Abstract : Electric traction is the most efficient traction system in the railway transportation. However, due to the expensive infrastructure and high power demand from the grid, the share of electric trains in the railway transportation is still lower than other trains. READ MORE

2. Energy Savings Using a Direct Current Distribution Network in a PV and Battery Equipped Residential Building
Abstract : Energy from solar photovoltaic (PV) are generated as direct current (DC) and almost all of today’s electrical loads in residential buildings, household appliances and HVAC system (Heating Ventilation and Air-conditioning) are operated on DC. For a conventional alternating current (AC) distribution system this requires the need for multiple conversion steps before the final user-stage. READ MORE

3. Optimal Energy Scheduling of Grid-connected Microgrids with Battery Energy Storage
Abstract : The coupling of small-scale renewable-based energy sources, such as photovoltaic systems, with residential battery energy storages forms clusters of local energy resources and customers, which can be represented as controllable entities to the main distribution grid. The operation of these clusters is similar to that of grid-connected microgrids. READ MORE

4. Energy Harvesting and Energy Storage for Wireless and Less-Wired Sensors in Harsh Environments
Abstract : Engineering requires sensors to control and understand the environment. This is particularly important in harsh environments. The drawbacks, especially in gas turbines is the complexity of installing a wired sensor and the weight of the wires. This makes wireless sensors attractive. READ MORE
