Modular Mesh Generation with Embedded Streamline Potential Grids
SPE Reservoir Simulation Symposium, 1999Abstract Reservoir grid generation can be simplified by decomposing the domain into a set of subdomains such that modular grid generation can be performed within each subdomain. The question of how to decompose the domain is addressed. Streamline-potential coordinates form an integral part of our domain decomposition strategy.

Grid disturbance analysis with Modular Load Flow
2016 IEEE 6th International Conference on Power Systems (ICPS), 2016Iterative load flow (ILF) is ill-suited for analyzing conditions immediately preceding blackouts since reactive power capacities of most generators are most likely exhausted. This makes choice of PV buses and specifying their voltages difficult. Improper voltage specifications at PV buses may result in non-convergence of ILF. We propose a non-iterative

Control of modular microgrids by varying grid frequency
2017 IEEE Manchester PowerTech, 2017The increasing number of distributed energy resources, energy storage systems and controllable loads, summarized as decentralized actors (DAs), causes new challenges for grid operation and planning. At the same time, it leads to new capabilities of forming microgrids (MGs) with controllable generation, consumption and storage functionalities in public ...

A modular shadow-gridded high power switch tube
1987 International Electron Devices Meeting, 1987This paper describes the design and performance of a novel magnetless high power switch tube. The basic device has an operational microperveance of over 280 in the on-mode (for a low switch voltage drop at high levels of transmitted current). Further, it can hold off voltages up to and beyond 25 kv in the off-mode.

Modeling of modular multilevel converter for grid application
2017 4th International Conference on Power, Control & Embedded Systems (ICPCES), 2017Modular Multilevel Converter is a widely accepted technology for HVDC applications. It consists of several sub-modules or cells connected in cascade. These are bidirectional chopper cells and each one of them has a floating capacitor. This paper discusses the modulation and voltage balancing strategies which are essential for the converter to work as ...
