In order to optimize the efficiency of renewable energy sources they are connected in a form of AC and DC Microgrids. Furthermore the increased number of DC loads has shifted the view to DC Microgrids. This paper presents the stability and maximum time delay calculation for a DC Microgrid implementing master-slave control strategy. The communication between the master and the slave is achieved through...
Load frequency control systems used to rely on dedicated communication links. The deregulation of the electricity market and the emergence of the Microgrids and Smartgrids made the open communication infrastructure an exigent need for future power system. In this case the load frequency control signals will be exchanged through communication network. The communication network is characterized by variable...
The rapid development in communication networks made them very attractive to replace conventional wiring in distributed power electronic systems. Parallel DC/DC converters are one of the important distributed power electronic systems. Conventionally, the controllers exchange the control signals through wires. This reduces the reliability and increases the system cost and complexity. Replacing them...
The rapid development and the low cost of the communication networks made them a viable alternative to conventional wiring in distributed energy systems. Closing the feedback through a communication network forms a networked control system which is characterized by time delay and packet loss. However, exchanging the control signals over communication networks reduces the complexity in the wiring and...
Microgrids and Hybrid Electric Vehicles rely on parallel DC/DC converters for power generation. DC/DC converters are connected in parallel to share the same load. The control signals are distributed through wires. The wiring increases the complexity and reduces the reliability. The recent advances in shared wireless networks made them viable and cheap alternative to direct wiring. Distributing the...
The key feature of Networked Control Systems (NCSs) is that the information is exchanged through a network among control system components. So the network induced time delay is inevitable in NCSs. The time delay, either constant (up to jitter) or random, may degrade the performance of control systems and even destabilize the systems if the systems are designed without considering the effects of the...
