Microgrids operation and control
... • Sources with a dc output or an ac output with a frequency different from that of the microgrid main bus need to use an inverter to be integrated into an ac microgrid. When implementing droop control, the P-ω and Q-E droop regulators are used to emulate the inertia of an ac machine. • Issues when i ...

Noise-Shaping Techniques Applied to Switched
... filter out, as their frequencies vary with load and input voltage. As a result, circuits that use the regulated voltage are susceptible to tones in the frequency region of operation. Furthermore, these tones can mix with unwanted signals outside the band of interest and modulate into the desired sig ...

Distributed control system
A distributed control system (DCS) is a control system for a process or plant, wherein control elements are distributed throughout the system. This is in contrast to non-distributed systems, which use a single controller at a central location. In a DCS, a hierarchy of controllers is connected by communications networks for command and monitoring.Example scenarios where a DCS might be used include: Chemical plants Petrochemical (oil) and refineries Boiler controls and power plant systems Nuclear power plants Environmental control systems Water management systems Metallurgical process plants Pharmaceutical manufacturing Sugar refining plants Dry cargo and bulk oil carrier ships Formation control of multi-agent systems
