Application of suitable 4 F 3[1] summation theorems leads to a number of formulae expressing certain double power series with equal variables as single power series. These formulae yield as particular cases reduction formulae expressing Kampé de Fériet functions F q:1:1 p:2:2[ X, X] ...

In respect to wind turbine systems, ANNs can be applied for active pitch control to control the pitch angle, when the wind speed is high [106, 108]. Sindareh‐Esfahani and Pieper [109] developed a discrete‐time piecewise affine (PWA) model for advanced control on a wind turbine system...
The equality constraints for the balanced load flow equations are as follows: $${P}_{Gi}-{P}_{Di}=\left|{V}_{i}\right|\sum_{j=1}^{NB}\left|{V}_{j}\right|({G}_{ij}\mathrm{cos}{\delta }_{ij}+{B}_{ij}sin{\delta }_{ij})$$ (45) $${Q}_{Gi}-{Q}_{Di}=\...

As highlighted in this analysis, the study's power grid is a hybrid system that contains a significant proportion of RESs, with a focus on wind generating facilities. The following formulae can be used to calculate wind output power3,4. ...
- This Act shall provide a framework for the restructuring of the electric power industry, including the privatization of the assets of NPC, the transition to the desired competitive structure, and the definition of the responsibilities of the various government agencies and private entities....
Although this construction is primarily intended to give a method for computing formal power series solutions, we will use it for proving theq-analog of some results concerning the nature of power series solutions of non linear differential equations. Namely, we show properties about the growth of...
The observed signal is often a pure tone, for which narrow-band filtering will produce a considerable improvement in signal-to-noise (S/N) ratio. If the noise is “white,” that is, has a uniform spectral power density, then a reduction in bandwidth from BW to BN improves the S/N ...
The well-known formula for this arrangement (51) is (3.32)Ce=2πεlln[2ld4s+l4s+3l] And for s ≪ 1: (3.33)Ce≈2πεlln1.15ld Since even more accurate approximations will not contribute much to the result as shown by Zaengl (51) and Luehrmann,(52) one may evaluate eqn...
