Open image in new window Fig. 11 Power of controllable devices for Case 2. By considering the equivalence of real power to reactive power in voltage regulation, a new partition method is proposed for hybrid AC/DC medium voltage distribution networks.
In Case 1 the equivalence of real power to reactive power is considered in partition results, and in Case 2 only the capability of reactive power is considered.
Case studies were conducted to demonstrate the superiority of proposed priority-based coordinated control strategy based on multi-objective partition considering the equivalence of real power to reactive power.
However, the regulation efficiency in Case 1 is better than that in Case 2, because some nodes, e.g. node 6, belong to the nearest partition after considering the equivalence of real power to reactive power.
It is defined using the following equivalence of the power supplied by external loads to the power dissipated due to slip: begin{array}{*{20}l} boldsymbol{P} cdot dot{boldsymbol{F}} = sum_{alpha} tau^{alpha} v^{alpha}.
Periodic boundary conditions were used and the stress resultants were evaluated accounting for the equivalence of mechanical power between scales (Hill-Mandel principle).
We establish the equivalence of the Hermite and power moments in the construction of dispersion approximations.
The equivalence of real and reactive power adjustment on voltage control is considered in control area partition optimization, in which regulation efficiency and capability are taken as objectives.
18 The trial was designed as an equivalence trial, which was powered for equivalence of Diuretics to No-diuretics group on the primary end point.
For the secondary immunogenicity endpoints, anti-CS titres, a sample size of 75 evaluable subjects per group would have 90% power to demonstrate equivalence of the two vaccine regimens under comparison (i.e. x versus y, 95% CI of the GMT ratio x/y is within the range 0.33 to 3.0) at any time point assuming a log standard deviation of 0.9 in both groups, alpha = 0.025.
