Inverters with distributed storage(DS) play a very important role in a microgrid. A new kind of inverter called virtual synchronous generator(VSG) is proposed in this paper to emulate the behavior of synchronous generator(SG) in the utility. The core algorithm of VSG is to employ an electromechanical transient mathematic model of round SG. There are two important operation modes in microgrid: active...
The resonator simulator provides a new method for researching the resonant sensor closed-loop circuit. In this paper, the mathematic model of silicon pressure resonator is established to design the circuit with resonator characteristic. Firstly the relation between pressure and the amplitude-frequency characteristic of the resonant beam is deduced. Secondly, combined with the in-out of excitation...
