In the future, it is expected that the electrical energy production area and the belonging network grid structure will change. It is expected that an increased amount of dispersed renewable generation units, such as photovoltaic (PV) systems, biomass systems and small wind turbines will be connected to the network grid at the distribution level. At the same time connection of large offshore wind farms at the transmission level will also be in focus. This may offer potential economic, environmental and technical benefits, but it also presents a great number of challenges and uncertainties. The introduction of dispersed generation and wind farms will affect the network technically in a number of ways concerning load flow pattern, power quality problems, voltage control, frequency control and reactive power control. Dispersed generation units and wind farms could alter the fault level and the fault current in the distribution and transmission system. However, this may require adjustments or replacements of the protection system. Also attention should be paid to the availability and security. You will study topics like Electric Power Systems and High Voltage Engineering (Energy Engineering), Aalborg University Should the entire high voltage network be laid in cables? How should this be done? How would the future distribution network be, including decentralised supply units? What control strategy would be required? Should the customer pay time-dependent prices to encourage adjustment of consumption patterns? Should the distribution network be able to run independently in the future (disconnected from the transmission network)? How do we control the balance between production and consumption in a future network supplied by sustainable energy sources with fluctuating production and consumption?
