The vertical water-exit process of object involves the problem of the two-phase flow and fluid-structure coupling which is one of the key problems that need to be solved urgently in dynamic modeling and controller design of the water-exit stage of the object. Nowadays, added-mass is relatively mature and convenient method of decoupling. Because of the time-variant characteristic of the object's added-mass...
Now more and more distributed generations will be connected to distributed power system. It's found that different distributed generation has its own operation characteristic such as fluctuation and uncertainty. When micro-grid is to be island the voltage and frequency will change, so different control modes have been used on different distributed generation. Different kinds of distributed generation...
When we consider risk as a type of financial asset, and accordingly transform the measurement of risk into the pricing of asset (i.e. risk), a series of assets pricing methods in financial economics can be applied. Furthermore, Equilibrium Pricing Principle has proved the rationality and feasibility of this consideration, and points out that traditional risk measurement method, VaR (Value at Risk)...
Recently inverters are all-pervading used as the connective instrument of distributed generations and distributed power system. When inverter interfaced distributed generations are connected to the distribution system, it may bring some new problems on load flow and fault characteristic and protection. The analysis on steady characters of PQ control mode and VF control mode inverter interfaced distributed...
