Power Flow Control by Unified Power Flow Controller
Mehran University Research Journal of Engineering and Technology, 2020 The demand of energy usage is increasing rapidly and to meet the energy requirements, best possible transmission systems should be adopted to avoid energy losses in our transmission systems. In Pakistan’s WAPDA (Water & Power Development Authority) system, the rapid increase in load and less generation capacity has increased load shedding thought ...

Optimal Power Flow Using Graph Neural Networks [PDF]
IEEE International Conference on Acoustics, Speech, and Signal Processing, 2019 Optimal power flow (OPF) is one of the most important optimization problems in the energy industry. In its simplest form, OPF attempts to find the optimal power that the generators within the grid have to produce to satisfy a given demand.
