With the rapid development of electrical power systems in recent years, microgrids (MGs) have become increasingly prevalent. MGs improve network efficiency and reduce operating costs and emissions because of the integration of distributed renewable energ
The synchronous machine, exciter, power system stabilizer (PSS), transmission lines, and the power electronic-based devices—flexible alternating current transmission system (FACTS)—are major power system components that play a large role in the generation, transmission, and distribution of power. ...
In both cases, a controllable three-phase rectifier supplies the excitation winding on the rotor of the synchronous machine. As it is well-known, the cycloconverter is a frequency converter which converts power directly from a fixed frequency to a lower frequency. Each of the motor phases is ...
This research contributes to the current knowledge in several ways. The study assesses the proposed hybrid renewable energy system (HRES) and how it may be included into the distribution network of Debre Markos University. The study utilizes backward/forward sweep load flow analysis and metaheuristic ...
other hand, the electrical machines have pros and cons, as using these machines requires the use of an inverter to supply them and control the resulting energy. In the case of synchronous machines, an inverter is used that is connected to the stator of the machine. But in the case of asy...

using ESS is not yet established for industrial applications. Besides, the active frequency damping control concept using BESS was proposed recently. The control inputs such as off-nominal frequency, power angle of inverter interfaced renewable generator, and rotor angle of the synchronous generator ...
A complete power electrical control unit consists of functions for pulse width modulation (PWM) control, data conversion, and communications; filtering and protection; a three-phase permanent magnet synchronous motor (PMSM) drive; a control module; and a monitoring module...
When the output from renewable energy generation sources exceeds the current load demand, and no additional energy supplementation is needed, any surplus energy is redirected to operate the motor pump set. This set-up is responsible for raising water from the lower reservoir to the upper reservoir...
