Mathematical Programming Approach For The Design Of Satellite Power Systems, Allen Flath Iii
Theses and Dissertations--Electrical and Computer Engineering
Satellite power systems can be understood as islanded dc microgrids supplied by specialized and coordinated solar cell arrays augmented by electrochemical battery systems to handle high-power loads and periods of eclipse. The periodic availability of power, the limited capacity of batteries, and the dependence of all mission service on power consumption create a unique situation in which temporal power and energy scarcity exist. A multi-period model of an orbital satellite power system’s performance over a mission’s duration can be constructed. A modular power system architecture is used to characterize the system’s constraints. Using mathematical programming, an optimization problem can be …
Power Control Of Single-Stage Pv Inverter For Distribution System Volt-Var Optimization, Xiao Liu
Power Control Of Single-Stage Pv Inverter For Distribution System Volt-Var Optimization, Xiao Liu
Theses and Dissertations--Electrical and Computer Engineering
The output power variability of intermittent renewable sources can cause significant fluctuations in distribution system voltages. A local linear controller that exploits the capability of a photovoltaic inverter to provide both real and reactive power is described. This controller substitutes reactive power for real power when fluctuations in the output of the photovoltaic source are experienced. In this way, the inverter can help mitigate distribution system voltage fluctuations. In order to provide real and reactive to the grid, a three-phase grid-connected single-stage photovoltaic system with maximum power point tracking and power control is described. A method of reducing the current …
