Simplification of water distribution networks using non-linear Thevenin theorem and its application for maximum power transfer

Journal of Hydroinformatics, 2022
The boundaries of existing cities are expanding rapidly due to the exponential growth in urban population. Therefore, the existing water distribution networks (WDNs) need to be expanded up to the newly developed areas to meet the additional water demand.

Wireless Power Transfer: Types of Reflected Impedances and Maximum Power Transfer Theorem

IEEE Antennas and Wireless Propagation Letters, 2020
In this letter, different types of resonant reflected impedances (real, imaginary, and negative) and conditions for their existence are introduced using power flow paths. The condition necessary to achieve maxima of power delivery at a high (>0.5) system efficiency is derived while maintaining a power factor of 0.85 or above.

Quantum analog of the maximum power transfer theorem

Optics Express, 2022
We discover the quantum analog of the well-known classical maximum power transfer theorem. Our theoretical framework considers the continuous steady-state problem of coherent energy transfer through an N-node bosonic network coupled to an external dissipative load. We present an exact solution for optimal power transfer in the form of the maximum power

Case teaching of maximum power transfer theorem in PV power system

Advances in Social Science, Education and Humanities Research, 2014
The maximum power transfer theorem is discussed from the viewpoint of the case teaching method in this paper. Based on the output characteristic of PV cell, the principle of maximum power transfer in PV cell is analysed in detail. And simulation was carried out to verify maximum power transfer.
