![]() Demand-side management in DC microgridsĮngineers (TU/HTO) in electrical engineering or physics who are interested in direct current microgrids.Energy Management Systems for DC microgrids.Operation and Control of Power Electronic Converters in DC Microgrids.Challenges introduced by Distributed Generation.Furthermore, attention will be given to the design of energy management systems for DC microgrids including concepts as Demand Side Management. Several alternatives for the provision of ancillary services by means of DC microgrids will be presented. Design and layout of AC and DC micro-grids will be defined including sizing of different components. This course focuses on the modelling and control of DC micro-grids.

When there is a surplus power in the micro-grid, surplus power is returned to the system power.Īt 8h, electricity load No. When there is a power shortage in the micro- grid, the system power supplies insufficient power. SOC (State Of Charge) of the storage battery is fixed to a constant and does not change since charge or discharge of the storageīattery are not performed by the battery controller. The storage battery supplies the insufficient current when the power of the micro-grid is insufficient and absorbs surplus current from the micro-grid when its power is surpasses the electric load.įrom 12h to 18h, battery control is not performed. Then, the active power of secondary side of the pole mounted transformer is always around zero. The battery control performs tracking control of the current so that active power which flows into system power from the secondary side of the pole transformer is set to 0. ![]() It reaches the peak amount (5 kW) from 14h to 15h.Īs a typical load change in ordinary houses, the amount of electric power load reaches peak consumption at 9h (6,500 W), 19h, and 22h (7,500 W).įrom 0h to 12h and from 18h to 24h, battery control is performed by battery controller. Simulationįrom 20h to 4h, the solar power generation is 0 W. ![]() The control strategy assumes that the microarray does not depend entirely on the power supplied by the power grid, and the power supplied by the solar power generation and storage are sufficient at all times. The solar power generation and storage battery are DC power sources that are converted to single-phase AC. The micro-array is connected to the power network via a transformer mounted on a post which lowers the voltage of 6.6 kV to 200 V. Three ordinary houses consume energy (maximum of 2.5 kW) as electric charges. It absorbs surplus power when there is excess energy in the micro-network, and provides additional power if there is a power shortage in the micro-network. The storage battery is controlled by a battery controller. Energy sources are an electricity network, a solar power generation system and a storage battery. The micro-grid is a single-phase AC network. ![]()
