'power combination' is correct and usable in written English
You can use it to refer to two or more items, characteristics, or actions that can create a strong or influential result when used together. For example, "The unique power combination of his intelligence, ambition and charisma made him an unstoppable force in the business world."
That include a power combination of Entertainment chief Robbie Bach, Office Business czar Stephen Elop, and Online Services Group head Qi Lu.
Now, when CU reuses with D2D pair, the optimal power combination ( left({p}_i^{ast },{p}_j^{ast}right) ) satisfied with constraints (5a)–(5d) can be achieved.
Next, we seek the optimal transmit power combination for the CU and D2D pair in the admissible area and it is demonstrated that the optimal value can be selected from several points on the border of the admissible area.
In the simulations, the constant impedance model or the constant impedance + constant power combination model are applied, so the load change is caused by the change of the node voltage when the system frequency drops.
DESS can regulates voltage by a variety of ways, such as absorption or generation of active power, absorption or generation of reactive power, combination of active power and reactive power [15 17].
Seek the optimal power combination ( left({p}_i^{ast },{p}_j^{ast}right) ) to make ( Rleft({p}_i^{ast },{p}_j^{ast}right)=max Rleft({p}_i,{p}_jright) ).
The matrix form of this game is composed of 390,625 joint strategies, and there may exist different power combinations (joint strategies) which achieve the same Shannon channel capacities.
We will later compare this approximation with the optimal solution obtained through an exhaustive search over all possible transmit power combinations.
In Section 6, we then compare our approximation with the global optimum that is found by an exhaustive search over all possible power combinations.
It is demonstrated in this paper that only several power combinations need to be computed and compared, and thus the optimal solution can be achieved, which avoids the complex optimization algorithms.
In the case of DIV and DRCP, we include the optimal solution obtained with an exhaustive search over all the possible power combinations, named respectively "DIV optimal" and "DRCP optimal".
